About the Role
You've shipped real software. You've sat in a room with stakeholders and pushed back on a bad idea. You've built something with LLMs that ran in production and learned, the hard way, what doesn't make it past the demo. Now you want to do more of that, faster, with bigger problems and better tools.




As a mid-level FDE at Firstsource, you'll be embedded with a named client, own a problem end-to-end, and partner with junior FDEs and our internal AI platform team to build solutions that operate — not just impress. You'll be expected to think about extensibility on day one and ship working prototypes by day five.
What You'll Own
End-to-end delivery of Gen AI solutions inside a client engagement — from discovery to production
Architecture decisions on document pipelines, agent systems, RAG infrastructure, copilots, and operational AI
Hardening LLM features: evals, prompt versioning, cost & latency optimisation, observability, guardrails
Stakeholder management — translating client problems into technical scope, and technical realities back into business language
Mentoring 0–2 year FDEs on the engagement, reviewing their code, and accelerating their ramp
Contributing patterns and platform components back to Firs
