light-inc - AI Platform Engineer

• Architect the Engine: Design and build a production-grade Agent Runtime that handles tool registration, permissions, timeouts, and retry semantics for autonomous agents. • Define the Standard: Evolve our internal GenAI Client and SDKs to create a "paved road" for product engineers, standardizing how every team at Light interacts with LLMs. • Solve for Trust: Build the "CI/CD for AI", implementing reliability frameworks, golden datasets, and regression testing pipelines that allow us to deploy prompts and agents with confidence. • Expand the Ecosystem: Lead the integration of Light with external platforms via the Model Context Protocol (MCP) and automation tools like n8n. • Governance & Scale: Design the guardrails, rate limits, and caching strategies that ensure our AI infrastructure scales predictably and cost-effectively. • Strong Systems Engineering Background: You have significant experience building scalable backend systems or internal developer platforms. You care deeply about latency, observability, and clean APIs. • AI Native Mindset: You live on the bleeding edge of the AI landscape. You understand the difference between an Agent and a Chain, you have experimented with MCP, and you keep up with the latest releases from OpenAI, Anthropic, and DeepSeek. • Polyglot Capabilities: You are proficient in Kotlin (our core backend language) or have a strong willingness to learn it. • Focus on Determinism: You hate flaky software. You understand that trust is the biggest bottleneck to AI adoption, and you know how to build the evaluations and logging necessary to generate that trust. • Force Multiplier Attitude: You get more satisfaction from unblocking 10 other engineers with a great tool than from shipping a single feature yourself. • In addition to being part of a great team and working in a really fun and innovative environment, we offer: • 💸 Competitive salary + potential stock options • 🏝 25 days of annual leave + public holidays (in your country) • 🥳 Regular socials and company off-sites. • 🚀 A huge opportunity to shape a market-defining product and engineering culture • The famous last words • At Light, we’re building the most trusted financial platform in the world — and trust starts with security. As our Security Lead, you’ll help us earn that trust every day.
