Software Engineer (AI-Native Platform & Integrations)

What we’re looking for

• Strong, practical software engineering skills; you can ship end-to-end and unblock yourself.
• Experience building SaaS products with APIs, data models, and production constraints.
• Deep comfort with integrations (OAuth2, webhooks, API pagination, rate limiting, sync semantics).
• “Vibe coding” mindset: you use AI tools effectively (Copilot/ChatGPT/etc.) to move fast without sacrificing correctness—good taste around tests, interfaces, and guardrails.
• Familiarity with MCP-style tool interfaces and/or building tool servers.
• Clear communicator who can explain tradeoffs and keep stakeholders aligned.
