At Nextlane , we don’t just develop software solutions – we create the future of the automotive industry. We are a company that combines advanced technology with a clear vision: simplifying and digitizing every step of the automotive customer journey, empowering manufacturers and dealerships to thrive in a constantly evolving market. So… What does it mean to be a #Nextlaner? Be committed to provide an environment where you can learn, grow, and collaborate on projects that make a general impact. Our success is measured not just by results, but also by the growth and satisfaction of those who are part of our company. 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. 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.
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. Add SLOs, alerts and contract tests to the top APIs; release in stages, with rollback.
• Make AI coding assistants and agents (Claude Code or similar)

• Bring AI code review and AI-built tests into the pipeline, with our Developer Experience team.

• 8+ years in software engineering, at Senior or Staff level.
• Modernised long-lived software while keeping it running.
• Used AI coding assistants and agents on large, long-lived codebases, beyond demos. Fluent English (mandatory; interviews in English).
