Software Engineer, Backend

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.

Job description

Normal Computing | Build with Us

Normal is an applied AI company solving the hardest problems in AI and silicon. We build foundational hardware and software for the semiconductor industry, critical AI infrastructure, and the broader systems that power our world, in partnership with the world's most advanced institutions. We work as one team across New York City, Silicon Valley (Mountain View), London, Copenhagen, and Seoul.

The Role

Normal is building software for semiconductor engineers: a local CLI that works inside real chip design environments, a web product for managing projects and reviewing results, and backend services that coordinate long-running work across both. Making those pieces feel like one dependable product is a backend engineering problem.

This role spans the backend surface behind that product. Depending on the project, you might design an API shared by several services, evolve a database model without breaking existing sessions, make a state transition idempotent, improve a local agent loop, or remove a deployment or performance bottleneck. The common thread is production software with real state, real failure modes, and users with complex workflows.

We use AI in the product, but this is not an ML role and prior experience with agents is not required. We are looking for backend engineers who enjoy making complex systems clear, reliable, and easy to operate.

What You Will Own

Your scope will depend on your experience, interests, and the team’s priorities. You would likely go deep in a few of these areas rather than own all of them:

• 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.

What Makes You a Great Fit

• 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.

Bonus Points

Experience with any of the following is helpful, but not required:

• Postgres, Redis or Valkey, event-driven architectures, or high-volume stateful services

• Kubernetes, containers, cloud infrastructure, or deploying software in resource-constrained, on-premises customer environments

• Developer tools, CLIs, workflow engines, job schedulers, or distributed execution systems

• Semiconductors, EDA, or hardware engineering workflows
