Job description

Job Description

the company is seeking a Sr. Backend Engineer to join the company's Disease Management team based in Denmark and the United States. In this role, you own a service or domain end-to-end — design, implementation, tests, and the controls that prove it works — making sound design calls within the platform architecture. You’re a go-to for hard backend problems, you mentor less-senior engineers, and you have a strong drive to ship working software. The Sr. Backend Engineer's responsibilities include but are not limited to:

• Design and build backend services in our Python stack: APIs, data models, migrations, async/eventing, and the integrations that feed the platform.
• Own a domain end-to-end — from design through tested, observable, production-ready code, with the quality controls that back it up.
• Build and harden third-party integrations (wearables, clinical data): OAuth, webhooks, retries, idempotency, token refresh.
• Own your domain’s reliability: instrument it (metrics, traces, logs), define and defend its SLOs, write actionable alarms, and take a turn on-call. Contribute to the infrastructure that runs it (Terraform / AWS).
• Raise the quality bar: meaningful tests, good reviews, and safety/privacy treated as design inputs (encryption, least-privilege, PHI handling).
• Mentor mid-level engineers and lift the team’s standards.
• Use AI coding agents to move fast — and verify and own what they produce.

Qualifications

• Strong backend experience (Python / FastAPI / SQLAlchemy / Postgres or equivalent) and a record of owning features/services end-to-end.
• Solid grasp of API design, data modeling, testing, and integration patterns.
• Experience running services in production — observability (metrics/logs/ traces), SLOs, and enough infra/IaC familiarity to operate what you build (Terraform / AWS a plus).
• A bias to ship and a sense of ownership beyond your own commits.
• Comfort using AI coding agents day-to-day, with the judgment to check them.
• Clear communication — code, reviews, and writing others can follow.
• Health / regulated software (SaMD, IEC 62304, HIPAA) or other safety-critical domains.
• Healthcare data / interoperability (FHIR, wearables: Withings / Polar / Whoop / Fitbit, Apple Health / Health Connect).
• AWS / Terraform, Snowflake / dbt, or Flutter exposure.
