Backend Engineer — Production-Grade AI Infrastructure

Drive Capital; København; On-site; DKK 700,000 - 1,100,000; Full time

Job summary

Normal Computing in Copenhagen is building production software for semiconductor engineers: a local CLI, a web product, and backend services that coordinate long-running work. The role focuses on backend engineering rather than ML, emphasizing clear, reliable systems.

You will design APIs, evolve data models, and improve reliability, observability, and performance across distributed services. Collaboration across repositories and languages is expected to deliver durable, maintainable software.

Qualifications

• 4+ years of software engineering experience and a track record of shipping backend systems that other people depend on.
• Experience designing APIs and data models, and reasoning clearly about concurrency and state.
• Experience operating production services where reliability, observability, maintainability, and performance matter.
• Comfort reasoning about distributed failure modes such as retries, partial completion, duplicate work, cancellation, and recovery.
• The ability to debug across boundaries—from a client or CLI through services, databases, and deployment infrastructure.
• Pragmatic judgment about when to invest in a durable abstraction and when to ship the straightforward version.
• Range: you have gone deep in at least one area and can become productive in an unfamiliar codebase or technical domain.
• A product mindset: you care whether the system is understandable and dependable for the people using it, not only whether the code is correct.

Responsibilities

• Design stable, well-typed interfaces across CLI, web, and backend services.
• Evolve Postgres schemas, migrations, event histories, and other durable state.
• Build lifecycle, queueing, retry, cancellation, idempotency, and recovery behavior for long-running work.
• Improve software that runs across developer machines and containerized environments.
• Make failures easier to diagnose through metrics, traces, structured logs, health checks, and operator tooling.
• Improve how changes are tested, packaged, migrated, deployed, and recovered.
• Find and remove performance bottlenecks in APIs, database access, event processing, and execution paths.
• Deliver product changes that cross repositories, languages, and service boundaries.
