Senior Software Engineer

About The Role Rippletide is building the decision infrastructure that makes AI agents production-ready for enterprises — and we need Senior Software Engineers who can design and ship systems that matter. You will work on the core of our platform: the Decision Context Graph engine, our SDKs, our APIs, and the internal tooling that powers everything from real-time enforcement to auditability dashboards. This is a high-trust, high-ownership role on a small, exceptional team.

What You'll Do

• Design, implement, and maintain performance-critical backend services powering Rippletide's Decision Context Graph and enforcement layer.
• Build robust, well-documented APIs and SDKs that developers at enterprise companies use to integrate Rippletide into their AI agent workflows.
• Own reliability, observability, and performance of your systems end-to-end — from profiling to on-call to post-mortems.
• Collaborate closely with the Research team to translate neuro-symbolic breakthroughs into shippable, testable production components.
• Contribute to architecture decisions, code review standards, and engineering best practices as a senior voice on the team.
• Engage with enterprise customers during integration phases, diagnosing issues and building solutions in tight collaboration with Solutions Engineering.

What We're Looking For

• 5+ years of professional software engineering experience with deep expertise in Python, Go, Rust, or C++.
• Proven ability to design and ship complex distributed systems in production — you have the scars and the learnings.
• Strong foundation in data structures and algorithms, with particular affinity for graph-theoretic problems.
• Experience building APIs and SDKs used by external developers; you care about ergonomics and documentation.
• Comfortable working in a small, fast-moving team with high ambiguity and broad ownership.
• Based in or willing to relocate to Paris.
• Entrepreneur mindset — you treat problems as opportunities, take ownership instinctively, and move with urgency.

Nice to Have

• Experience with graph databases (Neo4j, TigerGraph, Dgraph) or knowledge graph systems.
• Familiarity with LLM integration, agent orchestration frameworks, or ML infrastructure.
• Open-source contributions or a public technical portfolio.
• Previous experience as a founder or co-founder.

What We Offer

• Competitive salary and meaningful early-employee equity (BSPCEs).
• Ownership of critical systems in a company shaping the future of enterprise AI.
• Paris HQ at Station F with a culture of intellectual rigor and creative freedom.
• Learning budget for conferences, open-source work, and publications.
• Comprehensive health coverage and transport reimbursement.
