About the role:
Platform is the integration layer every Nextlane product connects through: the APIs, gateways and integration services that link dealers' management systems (DMS) with car makers (OEMs), partners and our cloud products.
As a Senior or Staff Software Engineer in Platform, you will design, build and run that layer - and help rebuild hundreds of OEM integrations on it, with AI doing much of the work under human review.
Your mission:
Make the platform something every team builds on, not around: stable and secure, one way in, and a new integration in weeks instead of months.This is a senior software engineering role first, with AI on top. You will write, review and ship code, own it in production, and make AI tools work on real, long-lived codebases - not demos.You will work with Platform Product, our architects, Developer Experience, QA, Security and the product teams that use the platform, across several European countries.
Your Responsibilities
As a key member of the team, you will be responsible for:
The integration layer
• Design, build and run the platform's APIs and integration services, behind one front door: our API gateway.
• Build OEM and partner integrations on our new integration platform - each one a reviewed recipe, not a project of its own - and move existing ones onto
it, domain by domain.
• Own what you build in production: monitoring, on-call, fixing what breaks.
Contracts and access
• Design versioned contracts for the core entities - customer and vehicle first, then workshop and parts - one shape, whatever the DMS.
• Apply one API policy - versioning, deprecation, error codes - so partners keep working when things change.
• Help build one sign-in and permission model: who may call what, for which dealer.
Stable and safe
• Add SLOs, alerts and contract tests to the top APIs; release in stages, with rollback.
• Build security in: no secrets in code, scans in every pipeline, vulnerabilities fixed on time.
• Lead incidents when needed; write the post-mortem and see its actions through.
AI in how we build
• Make AI coding assistants and agents (Claude Code or similar) work on our codebases: repository instructions, conventions, architecture maps, tools.
• Grow our AI assembly line for integrations - design, build and test, deploy -with a person approving the contract and the release.
• Bring AI code review and AI-built tests into the pipeline, with our Developer Experience team.
• Work inside a product team when it needs it, pairing on its code, so the AI tools keep working after you move on.
• Keep AI governed and measured: what data goes where, human review of every change; adoption, lead time and change failure rate, reported honestly.
Shared knowledge and the bar
• Keep designs, runbooks and post-mortems open and AI-readable, so anyone can ask what broke last time and what fixed it.
• Review code and designs, coach engineers, write short guides.
• At Staff level: set technical direction beyond the team, with our architects; lead migrations other teams depend on; help design how AI agents use the
platform safely - identities, limits, audit.
What We're Looking For:
Experience
• 8+ years in software engineering, at Senior or Staff level.
• Built and run production APIs and integrations that other teams or partners depend on.
• Modernised long-lived software while keeping it running.
• Used AI coding assistants and agents on large, long-lived codebases, beyond demos.
Languages
• Fluent English (mandatory; interviews in English).
• French is a plus.
Technical Skills
• Strong in C#/.NET or Java.
• API and contract design - REST, versioning, backward compatibility, API gateways, OAuth2.
• Integration patterns and frameworks (Apache Camel or similar), messaging and events.
• Azure and AWS; containers and Kubernetes.
• CI/CD (GitHub Actions or similar), automated and contract testing, observability (OpenTelemetry or similar).
• LLM tooling - context engineering, agents, MCP, evaluation - and AI security: data leakage, prompt injection, secrets.
Interpersonal Skills
• Earns trust fast in a team they don't belong to.
• Humble about what AI can't do yet.
• At Staff level, sets direction others follow.
Communication
• Shows rather than tells.
• Clear in writing - designs, pull requests, short guides.
Nice to have
• Automotive, DMS or CRM software.
• Software installed at customer sites.
• Built developer tools or AI workflows other teams use.
• Retrieval over code and documents.
• Open-source contributions.
