Nimbus
Remote
About Nimbus
Nimbus is a research team that focuses on developing an Ethereum client and library. We believe that the largest deployment of Ethereum will potentially be on embedded systems and Nimbus is designed to perform well on embedded, mobile and generally resource-restricted devices.
Building the stack from the ground up, we’re translating the latest Ethereum research into practical, performant and reusable libraries to provide a fertile exploration ground for further R&D.
About Nomos
Nomos is a new blockchain designed from the ground up with the original cypherpunk ethos: decentralisation, censorship resistance, permissionless-ness and privacy. It will serve as the trustless agreements layer of the Logos stack. The forthcoming Nomos network will provide a common infrastructure layer upon which communities and aspiring network states can build social, governance, and financial services that uphold their community members’ fundamental rights and values.
The role & responsibilities:
You will join the Nimbus team but work closely with Nomos to consume and provide feedback on specifications, ensuring a deep understanding of both projects. As a founding member of the Nimbus-Nomos team, you will also contribute to early architectural design and foundational decision-making.
You will:
- Develop a deep understanding of Nimbus and Nomos, including their architectures and designs.
- Consume specifications from Nomos and provide feedback where necessary.
- Collaborate with the Nimbus team to address complex, non-incremental challenges in the specifications, rather than relying on scoping smaller tasks to learn the codebase.
- Participate in shaping the initial architecture and design principles of Nimbus-Nomos, aligning them with decentralisation, privacy, and censorship-resistance goals.
Requirements:
- Strong understanding of blockchain technology and its underlying principles.
- Senior-level experience in the blockchain industry (several years), with a proven background in technical systems analysis and design.
- Technical background (Software Engineer or similar) and expertise in documentation, specification review, and architectural prototyping.
- You are proactive and communicative - making things happen comes easily to you.
- Commitment to privacy-focused, decentralised protocols and applications.
- Ability to work in early-stage, undefined environments where foundational contributions are critical.
Note: This role may evolve to involve architectural input beyond specification review. While the current focus is on analysing specs, your involvement in early design decisions will be an expected and integral part of the position, not a surprise or additional responsibility.
Bonus points:
- Experience working in an open-source organisation.
- You’ve used Nimbus Client or have worked in a privacy-focused project/organisation.
Hiring process:
- Intro call with our People Ops team
- Interview with Nimbus Team Lead
- Interview with Logos Program Lead
[The steps may change along the way if we see it makes sense to adapt the interview stages, so please consider the above as a guideline.]
Compensation:
The expected compensation for this role is 100k USD. We are happy to pay in any mix of fiat/crypto.
What You'll Do:
- Build backend systems in a modern monorepo. Work hands-on in a TypeScript + Node.js codebase, designing and developing backend services that power APIs, job schedulers, and index calculation engines. You'll write clean, testable code that supports both real-time and batch processing.
- Redesign and scale our job orchestration framework. Help the greenfield overhaul of our Node-based jobs infrastructure to create a fault-tolerant system supporting cron-like scheduling, DAG-based dependencies, and cross-language compatibility. Your work will enable scalable execution pipelines that are critical to our business operations.
- Maintain and evolve our data pipeline. Own key pieces of our modern data stack—including Fivetran for ELT processes, DBT for transformations, and Snowflake for warehousing—ensuring data integrity and quality for critical analytics purposes. You'll be responsible for the correctness and reliability of our data workflows.
- Collaborate directly with leadership. Work closely with the CTO and business leaders in our tight-knit team to scope, prioritize, and ship improvements to internal tooling and backend systems. You'll help manage timelines and expectations while balancing long-term vision with immediate business needs.
- Drive reliability and operational excellence. Join the on-call rotation, monitor system performance, and contribute to observability practices that keep our systems highly available and performant. You'll play a key role in incident response and infrastructure reliability.
- Contribute to engineering culture. Participate in code reviews, design discussions, and sprint planning. You'll help set quality standards and mentor others through collaboration and example.
What We're Looking For:
- +5 years of real world software engineering experience
- Proficiency in at least one modern backend language (e.g., TypeScript, Python, C++, Go, Java)
- Experience with data pipelines, databases, and cloud platforms (e.g., Mongo, Snowflake, AWS, Heroku)
- Familiarity with monitoring tools like Datadog and Sentry along with best CI/CD practices
- (Plus) Experience designing and implementing fault-tolerant distributed systems
- (Plus) Knowledge of job orchestration frameworks and DAG-based workflow systems
- (Plus) Experience with modern ETL/ELT processes and data transformation tools
- (Plus) Bachelor’s degree in Computer Science or equivalent

- Eligible for equity
- Health, dental, vision insurance
- 401K plan (company funded, no match required)
- Unlimited PTO plus 10 paid holidays
- Meals/snacks in office

Sherlock

About Sherlock
Sherlock believes that a sound currency and functioning financial system should be basic human rights. Sherlock’s mission is to help create an open, uncensorable financial system that is secure enough for billions of people to trust with their life savings.
Traditional blockchain security reviews are a good start, but it’s not enough. That's why Sherlock provides protocols with state-of-the-art, incentive-aligned audit contests, bug bounties and smart contract coverage.
Sherlock is the only security provider that includes a warranty after each audit. Sherlock customers get up to $500k of bug bounty and exploit coverage for the first month of launch after every audit.
Sherlock is also the only security provider to serve a customer’s full security needs, including collaborative audits, audit contests, bug bounties, and coverage.
Sherlock’s audit contests combine the best of traditional auditing with a competitive twist that results in hundreds of eyes looking at the codebase and some of the best security experts in the world surfacing issues that traditional audits miss.
Sherlock is the leader in auditing, running more public audits than any other provider last year. The Ethereum Foundation, Aave, Optimism, Cosmos, MakerDAO (now Sky) and the biggest crypto teams in the world choose Sherlock for their security needs.
Join Sherlock’s elite team on the ground floor, backed by some of the best Web3 and Silicon Valley VC firms such as Alliance, Archetype, IDEO, CoinFund, Lattice, Spartan, A Capital, and many others.Sherlock's Culture
Sherlock's culture is fast-moving, intense, and not right for everyone. Here are some common attributes among historically successful team members at Sherlock:
Mission-focus
Anyone in this for reasons other than creating the best financial coordination mechanism in history will either get too demotivated to last through multi-year bear markets or get too distracted during the frothy bull markets.
Willingness to work long, hard and smart
If Sherlock has any advantage, it is the willingness to work harder and think with more discipline than anyone else. This includes thinking from first principles about all important decisions and always thinking in tradeoffs and bets.
Owner mentality
Team members get ownership in Sherlock after a short time in this role, and each is expected to act like an owner of a Michelin-star restaurant where no detail is too small.
Builder mentality
Everyone at Sherlock is deep in the arena getting their hands dirty and this is a vulnerable position. There are no pure "idea people" or pure managers at Sherlock; everyone is in execution mode first and foremost.
Customer focus
It is too easy to sit behind a computer and build in an echo chamber. We must go out of our way to experience the customer's viewpoint as often as possible.
Professional athlete mentality
Professional athletes opt in to a high-performance, meritocratic culture. This creates an environment that brings out the best in people and rewards each for their respective performance. But it's also an environment where being in the 70th percentile in your role means you will have a short tenure on the team.
Comfort with directness and transparency
You must be comfortable giving direct feedback to others and receiving direct feedback yourself. "Not ruffling feathers" comes at the expense of moving in a suboptimal direction for too long. Sherlock is extremely transparent internally (and with customers) which means you can get involved in decisions made in any part of Sherlock.
The Role
Sherlock is already one of the leaders in blockchain security. But we’re looking to push the space forward further. Your role will be to contribute to the development of an exciting new initiative inside Sherlock.
This initiative will be spearheaded by the CTO of Sherlock directly, and other team members are some of the best in the world at what they do. It will be a small team of elite members working on a very interesting area of blockchain security. If you succeed, you’ll take on much of the new feature development for this initiative, with support from the CTO, Sherlock’s existing engineers and designers.
We are looking for someone who gets excited about the impact they can make in a role. The pace will be fast and the responsibilities will be high. Experience with Sherlock’s existing frontend and backend tech stack is a requirement. As is a strong base of Solidity knowledge. If you're serious about applying for this job and you've read this far, please email jack at sherlock dot xyz with 4-sentence answers to each of these three questions: What is the biggest individual contribution you’ve ever made to a software project? What gets you out of bed and excites you? Why should Sherlock select you over hundreds of other applicants?
Your role is to take on the highest impact position in a new initiative at Sherlock alongside a small team of elite players. In terms of the skills required in your role, a strong understanding of Python, Typescript and Solidity is a must. You’ll be responsible for full-stack development of features using Python in the backend, Typescript in the frontend, React and NextJS frameworks. You’ll be building an application related to Solidity smart contract security, so a strong understanding of Solidity is also required.
Any understanding of Solidity security vulnerabilities is a plus, but not a requirement for the role.The day-to-day responsibilities of this role include:
- Building features in an enterprise-grade application using Python (backend), Typescript (frontend), React and NextJS (10x weight)
- Understanding the user requirements of a Solidity developer and building based on their feedback (7x weight)
- Taking product direction from the CTO and working alongside designers (7x weight)
- Being extremely hungry/driven and ready to wear a different hat on any given day to help Sherlock succeed (5x weight)
Requirements
- Past experience building full-stack applications using Python (backend), Typescript (frontend), React and NextJS
- A strong understanding of Solidity smart contract development
- A strong interest in Solidity smart contract vulnerabilities
- A strong interest in AI applications and agentic workflows
Nice to Haves
- Past experience with Solidity smart contract development
- Past experience with Solidity smart contract vulnerability research
- Past experience with AI, LLMs, and/or building agentic workflows
What's in it for you
- Attractive base (payable in fiat or crypto) + material tokens/equity + benefits
- Flexible time-off policy
- Great healthcare
- Multiple offsites each year in places like France, Argentina, Thailand, etc.
- Be a huge contributor on a small elite team focused on an exciting area of blockchain security
- Root access to the decision-making process/criteria in all areas of Sherlock and the ability to work directly with the founders
- Move quickly and get stuff done on a small, elite team that has already made a big impact in the crypto space
- Play a huge role in defining the future of Sherlock and accomplishing the goal of making crypto/DeFi accessible to everyone
