About the role
Backend-focused member of staff role at Radical Numerics, building and operating backend services, APIs, and platform capabilities to power research and external workflows in AI-driven biology. Position involves end-to-end ownership, collaboration with researchers and product engineers, and emphasis on scalability, observability, and developer-friendly interfaces.
Responsibilities
- Build backend services for APIs and platform products. Design and implement backend systems that expose model capabilities, data services, and internal platform functionality through clean, reliable APIs.
- Own services end-to-end. Take backend systems from design docs through implementation, testing, deployment, monitoring, and iteration based on real usage patterns and operational feedback.
- Design for scalability and reliability. Build services that can handle growing traffic, large datasets, and demanding internal workloads while maintaining correctness, low latency, and operational robustness.
- Develop developer-friendly APIs and abstractions. Create clear, well-documented interfaces that make it easy for internal teams and external users to build on top of our systems.
- Improve backend architecture and platform foundations. Analyze existing systems, identify bottlenecks, and improve the maintainability, fault tolerance, and self-serve usability of our backend stack.
- Work closely with research and product teams. Partner with model researchers, infrastructure engineers, and application teams to understand requirements and translate them into backend systems that support real workflows.
- Build observability and operational tooling. Develop logging, monitoring, tracing, and alerting systems that help us understand service behavior in production and respond quickly when things go wrong.
Qualifications
- Strong track record building production backend systems, distributed systems, APIs, or data services.
- Proficiency in at least one backend language such as Python, Go, Java, or Rust, with strong software design fundamentals.
- Experience designing and operating production APIs, including interface design, authentication, versioning, reliability, and monitoring.
- Ability to own services end-to-end: architecture, implementation, testing, deployment, and operational support.
- Strong understanding of scalable systems design, including data modeling, concurrency, failure modes, and performance tradeoffs.
- Excellent written and verbal communication skills, especially collaboration across engineering, research, and scientific teams.
