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.

At Hiro, we build developer tools that bring Web3 to Bitcoin. Our suite of tools unlocks the full potential of Bitcoin through smart contracts, digital assets, and decentralized applications. With Hiro tools, developers can test and deploy smart contracts, spin up nodes and other server-side resources for scaling, and more. Building on Bitcoin is hard. Hiro's developer tools make it easier. We’re very proud to say that Hiro has consistently been recognized on Built In’s Best Places to Work list, including 2025’s Best Remote Startups to Work For, Best Startups to Work For in New York City, 50 Best U.S. Startup Companies to Work For, and 100 Best Remote Places to Work. Hiro is funded and backed by more than $75 million from Union Square Ventures, Y Combinator, Lux Capital, Winklevoss Capital, Naval Ravikant, and others. About the Opportunity Hiro is seeking a skilled and enthusiastic Senior Software Engineer to join our API team! If you’re passionate about building and scaling backend systems and APIs that empower developers, this role is for you. Our team thrives on collaboration, innovation, and a shared commitment to our mission. We care deeply about each other, the company, and the Stacks ecosystem, fostering a supportive and inclusive culture. As an API Software Engineer at Hiro, you’ll focus on designing, building, and optimizing the APIs that power our developer platform. In this remote-first role you will collaborate with a talented, distributed team and have broad ownership to implement services that serve our developer community. You’ll tackle challenges in scalability, performance, and security to ensure our APIs are robust and developer-friendly.

Join us at a rapidly growing startup where you can innovate freely and help bring the next generation of Web3 applications to Bitcoin. What You’ll Do:

Design, build, and maintain scalable backend services and APIs that drive Hiro’s developer platform (e.g. blockchain data, token metadata, ordinals) on Bitcoin and Stacks. Ensure high performance and reliability of our APIs – you’ll optimize endpoints, databases, and caching to handle increasing load with low latency and high uptime. Collaborate cross-functionally with product managers, frontend engineers, and DevOps to plan and implement new features end-to-end, delivering seamless experiences for developers. Write and automate thorough tests (unit, integration, performance) for your code – we use tools like k6 for load testing and Playwright for end-to-end testing – to ensure every release is of top quality. Participate in code reviews and architecture discussions, contributing to design decisions and championing engineering best practices to continuously improve code quality. Monitor and troubleshoot production systems as needed, debug issues across services and the stack, and implement fixes to maintain the stability and security of our platform. Work across the stack when necessary – primarily on backend APIs, but occasionally diving into frontend code or internal tools – to deliver complete solutions and improve our overall developer experience.

What We’re Looking For:

5+ years of software development experience building and shipping production applications, with a focus on backend systems or API-driven services. Strong proficiency in TypeScript/Node.js and/or Rust. (Our core services are built with these languages.) You can quickly pick up new languages and technologies as needed. Demonstrated experience designing, building, and scaling web APIs or microservices – you have tackled challenges in system design, performance tuning, and reliability for high-traffic services. Hands-on experience with relational databases, especially PostgreSQL – from data modeling and querying to performance optimization. Familiarity with modern cloud and container infrastructure. You’ve worked with containers/orchestration (Docker, Kubernetes) and deployed services on cloud platforms (we use GCP). Passion for code quality and automation. You write clean, maintainable code and have experience with automated testing and CI/CD pipelines (GitHub Actions or similar) to ensure smooth deployments. Excellent communication and collaboration skills. Comfortable working in a remote, distributed team and coordinating across time zones. Self-driven and ownership-minded. You take initiative, have a bias for action, and can manage projects end-to-end in a fast-paced environment.

We’d Also Like to See:

Blockchain/Web3 experience or interest. Familiarity with decentralized networks, or a keen interest in learning blockchain tech. Experience building developer-focused products. For example, working on developer tools, SDKs, or API platforms – understanding what makes a great developer experience. Exposure to performance tuning and observability. Knowledge of caching (Redis), profiling and optimizing high-traffic systems, and using monitoring/logging tools (Grafana, Prometheus, Loki) to ensure reliability. Infrastructure and DevOps know-how. Familiarity with infrastructure-as-code (Terraform), CI/CD tooling (ArgoCD), and global cloud networking (CDN/DNS/WAF like Cloudflare) is a plus. Open-source contributions or community involvement. Experience contributing to open-source projects or engaging with developer communities.

We’d love to hear from you even if you don’t have experience or interest in every bullet. What We’ll Offer:

Salary Range (regardless of location, benchmarked annually) $150,000 - $200,000. Company equity and Stacks (STX) tokens--STX is the native cryptocurrency of the Stacks network $500/mo co-working space reimbursement $1,200/yr stipend for learning and development $1,000/yr of charity donation matching to an organization of your choosing Daily Lunch Reimbursement (even if you’re remote!)
