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. 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!)
