Blockworks - Senior Backend Engineer

• As a Senior Backend Engineer at Blockworks, you’ll design, build, and maintain the systems that power our products end-to-end. From high-performance APIs to database architecture, you’ll own the backend layer that makes everything else possible. • You won’t just be handed requirements, you’ll help define them, scope projects, and make the architectural decisions that shape our technical foundation. Your work will directly impact our research platform (blockworksresearch.com) and our media site (blockworks.co; 1M+ monthly active users). • Every day will look a little different, but in general, you will do things like: • Architect, build, and ship backend systems that can scale to millions of requests/day • Design, implement, and optimize APIs that power our research and media products • Build pipelines to parse and model blockchain transactions and financial data • Own database design, optimization, and reliability (MySQL/Postgres) • Implement caching and performance strategies with Redis or similar tools • Lead backend feature development from planning to production release • Diagnose and resolve scalability, performance, and reliability issues under real-world load • Raise the bar on testing, monitoring, and observability across the stack • Collaborate with frontend, product, and data teams to ensure seamless integrations • Experimentation is frequent at Blockworks. Comfortability with being uncomfortable is a must. • What You’ve Done Before: • We value backend engineers who think holistically about systems, anticipate edge cases, and bring a balance of speed and rigor to shipping code. • 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’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’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. 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. Above all, you have strong attention to detail and pride yourself on writing clean, maintainable, and reusable code. • It’d Be Great If You’ve Done This: • 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.
