Senior Backend Engineer

Join Blockworks as a Senior Backend Engineer, where you'll design, build, and maintain the systems that power our products. You'll have a direct impact on our research platform and media site, and your work will involve architecting and optimizing backend systems, implementing APIs, and collaborating with various teams. Enjoy benefits such as health insurance, parental leave, a 401(k) plan, and a flexible working space.

• Architect, build, and ship backend systems that can scale to millions of requests/day, and design, implement, and optimize APIs that power our research and media products.
• Own database design, optimization, and reliability (MySQL/Postgres), and implement caching and performance strategies with Redis or similar tools.
• Lead backend feature development from planning to production release, and diagnose and resolve scalability, performance, and reliability issues under real-world load.
• You have a results-oriented attitude and a passion for delivering flawless releases and developing digital product pipelines (CI/CD pipelines)
• You're excited at the possibility of being on the ground floor of the design and development of backend strategies.
• You have a keen focus on backend and API development and Software engineering is your passion
• You have a proven track record facilitating engineering teams to increase productivity and quality
• We value backend engineers who think holistically about systems, anticipate edge cases, and bring a balance of speed and rigor to shipping code
• You love moving quickly in a fast-paced start-up, but you also bring intentionality, sustainability and scalability to your approach as an engineer
• You are a player-coach and a natural leader who understands the technical and human elements that go into great software design
• You bring a passion for designing and maintaining scalable API services that handle large amounts of data elegantly
• You’ve built fast, reliable API endpoints capable of handling over 1M requests per day, and you bring a mature approach to automated testing, monitoring, and observability
• You have a Bachelor’s degree in Computer Science, Engineering, or a related field (or equivalent work experience), and at least 5 years of professional experience as a Backend Engineer with a strong focus on backend development and architecture using TypeScript and Node.js
• You’re highly proficient in designing and optimizing relational databases such as MySQL and PostgreSQL, including data modeling and query optimization, and you know how to enhance performance and scalability through caching mechanisms like Redis
• Above all, you have strong attention to detail and pride yourself on writing clean, maintainable, and reusable code
• You’re skilled at troubleshooting and problem-solving in fast-paced environments, familiar with DevOps practices, CI/CD pipelines, and deployment tools, and you collaborate effectively across teams
• It’d be great if you’ve worked with frameworks like NestJS and database access layers such as TypeORM, and have experience supporting legacy migrations in PHP. Familiarity with AWS cloud infrastructure, exposure to ML/AI models, and hands-on experience in the crypto space are all strong pluses
• We know that diversity makes for the best problem-solving and creative thinking. We are dedicated to adding new perspectives to the team and encourage everyone to apply if your experience is close to what we are looking for
