Senior Software Engineer - Data Integration Focus (m/f/d)

At praxipal, we are building an AI-powered healthcare admin workforce to address the global shortage of medical staff.

Medical assistants are too valuable to spend their days chasing callbacks, cleaning up schedules, sending repetitive messages, or wrestling with invoicing and documentation workflows. Staff should spend time on patients. That's why we build Luna.

Our AI receptionist, Luna, answers and automates phone calls and she's loved by more than 100 medical practices. Right now, we're expanding her from calls to end-to-end patient communication across any channel. Over the next years, we'll grow her into an AI worker that automates all administrative processes in medical practices, embedded directly into the systems teams already use.

We're backed by one of Europe's leading investors and are one of the fastest growing healthtech startups in Germany. Our team has previously worked and studied at Palantir, Amazon, SAP, the University of Cambridge, and Hasso Plattner Institute.

We're hiring a Senior Software Engineer to build the integration foundation that enables Luna to automate practice workflows across hundreds of thousands of medical practices.

The role

Integration is the bottleneck and the unlock: Luna can only automate workflows when she can reliably read and write the source of truth inside a practice: schedules, patient context, messages, statuses, and workflow metadata. That data lives in practice management systems (PMS) and related tools.

This is a deeply technical, hands-on engineering role. You'll ship production integrations and make them safe to operate at scale: dependable writes, predictable retries, and failures that are diagnosable instead of mysterious. You'll harden integrations against real-world failure modes, and debug the issues that only show up in production. You'll also build internal tooling and patterns so integrations ship faster and break less.

This role is on-site in Berlin and requires fluent German.

What you'll do

Build integrations that unlock Luna's next capabilities

• Design and implement read/write integrations into third-party practice management systems

• Design infrastructure that scales to hundreds of thousands of individual practice servers

• Engineer reliability into the system: data consistency, idempotency, retries, error handling, observability

• Triage integration failures in production, communicate impact clearly, and harden the system so the same class of failure doesn't repeat

Raise the technical quality and velocity of integration work

• Build internal tooling that reduces integration effort (eg, integration test harnesses, replay tools, rollout safeguards)

• Build reusable patterns that let us support new vendors faster without creating a fragile maintenance burden

• Improve debuggability and incident response through better logs, metrics, tracing, and diagnostics

What we're looking for

Must-have

• Strong hands-on programming experience in TypeScript or Rust

• Proven experience building and running complex data integrations in production

• Strong understanding of integration patterns, distributed systems, and failure modes

• Comfort operating in messy environments (inconsistent behavior, missing docs, etc.)

• Clear communication under pressure (during incidents, vendor issues, competing priorities)

• Fluent German (spoken and written)

• Several years of experience in startups or scale-ups

• Excited to work on-site in Berlin in a fast-moving build-mode environment

Nice-to-have

• Prioritize work on healthcare software or practice management systems

• Familiarity with healthcare workflows, terminology, or data standards (eg FHIR)

• Experience improving reliability in production systems (observability, incident response, rollout strategies)

How we work

• We optimize for impact in production: automation practices trust daily.

• We're hands-on and pragmatic: upstream systems are imperfect; we build what holds up.

• We're direct and collaborative: strong opinions, low ego.

Location & compensation

• Location: Berlin (100% on-site)

• Competitive compensation: €100,000–€140,000 total compensation (cash + equity)

• Office perks : A beautiful workspace in Berlin Mitte, complete with a ping pong table, PlayStation, and VR setup.

• Team bonding : Regular get-togethers and happy hours.

• Health and productivity : Free dinners, subsidized lunches and sponsored gym subscription.
