Senior Software Engineer (Remote, France)

A 30-person SaaS startup backed by a startup studio is moving into its second product: a next-generation ERP for higher education institutions. The company already has a live product with paying customers and is now building a more ambitious platform with plans to expand beyond France. This is a hands-on senior role with no direct reports, where your influence comes through code, architecture decisions and raising the skill level of the team.

What you'll do

• Own features end-to-end, from design and development through releases and production monitoring, mainly on the ERP under construction
• Take part in architecture decisions with the CTO and help build a system that can scale
• Review pull requests, challenging code, data modelling, edge cases and maintainability
• Build robust APIs and resilient integrations for workflows with strong business constraints
• Design for reliability and observability so problems are caught before users see them
• Mentor developers on the team and share engineering practices

What you need

• 6+ years of experience, including products in production used by real users
• Have built and operated a backend over the long term and understand the trade-offs of architectures that must last
• Able to cover the full cycle: product understanding, system design, development, deployment and operations
• Strong instinct for edge cases and failure modes, especially when handling legal documents and critical customer data
• Prior experience as a Tech Lead, owning a system and guiding other developers
• Comfortable making decisions with incomplete information, and using AI tools daily
• Stack: TypeScript, Next.js, NestJS, MongoDB, Redis, AWS, Turborepo monorepo; observability with Sentry, BetterStack and OpenTelemetry

Applicants must be based in: France.
