  • Create tools and systems that make it easy to access, query, and visualize data (using tools like Redash, Metabase, or Looker)
  • Keep an eye on the evolving blockchain data ecosystem—experiment with new tools and techniques to stay ahead
  • Own your work end-to-end: from initial idea to deployment and maintenance

Who you are

  • Solid experience designing and maintaining scalable data architectures (data lakes, warehouses, pipelines)
  • Strong coding skills in Python and SQL
  • Comfortable working with blockchain data providers and APIs (e.g. Dune, Etherscan, CoinGecko)
  • Familiar with decoding Ethereum transactions and simulation tools (e.g. Tenderly, Phalcon)
  • Experience with modern data orchestration frameworks (Dagster, Airflow, or Prefect)
  • You write clean, tested, and well-reviewed code and follow best practices for deployment and monitoring
  • You’re a self-starter, collaborative, and not afraid to take ownership

Nice to Have

  • Familiarity with cloud platforms (AWS, GCP, etc.)
  • Previous experience in a startup or high-growth environment
  • Experience contributing to or using open-source data/analytics tools in the Web3 space

## What We Can Offer You

  • Flexible work environment: Join our hub in Lisbon whenever you want or work remotely
  • Token plan: Have a stake in our mission and shape the future of CoW DAO
  • Periodic gatherings: Meet your teammates in person during regular team retreats
  • Conference allocation: Stay up to date with the latest in Web3 using our conference budget
  • Learning budget: Support for personal and professional development

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. You’ll work across a modern, open-source tech stack (TypeScript/Node.js, Rust, PostgreSQL, GCP, Kubernetes, etc.), leveraging CI/CD and automation (and even AI-assisted tools) to ship high-quality code efficiently. 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!) Open Vacation Policy, take the days you need Family-Friendly Health Benefits Free Life and Disability Insurance Health and dependent care (FSA) Up to 16 weeks of paid parental leave Pre-tax commuter benefits 401k with 3% match

Please note that benefits vary by country, the ones shown above are for our full time U.S. based employees. Benefit information for non-US based positions will be provided to individuals who interview for those roles. Due to legal and logistical constraints, we are currently only able to hire candidates residing in the United States, Canada, and select countries in the EU. Hiro is proud to be an equal opportunity employer and deeply cares about building a diverse team. Hiro is committed to building an inclusive environment for people of all backgrounds.

ABOUT DOUBLEZERO

DoubleZero is a decentralized, permissionless protocol that revolutionizes network performance for distributed systems like blockchain. The mission is simple: increase bandwidth and reduce latency.

DoubleZero increases bandwidth by filtering junk data that currently plagues validators and other network operators. DoubleZero reduces latency by connecting these filters with underutilized private fiber links in the form of a mesh network. By combining these improvements and routing the right data through optimized, low-latency paths, the DoubleZero protocol empowers blockchains and other systems to reach performance levels that are currently impossible.

In short, DoubleZero is a new Internet for distributed systems. It is supported by two organizations: DoubleZero Foundation, which drives the adoption, decentralization, security, and advancement of the protocol; and Malbec Labs, which develops the technical components of the protocol itself. We look forward to hearing from you.
