• 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.

What We’re Looking For

• 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, along 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 the ability to collaborate across engineering, research, and scientific teams.

Nice to Have

• Experience with event-driven systems, streaming infrastructure, or workflow orchestration.
• Experience with SQL, OLTP/OLAP systems, or data platforms that support analytics or model-facing applications.
