realfast is India's first post-AI IT services company, built from scratch around one metric: how quickly a signed contract becomes working software a client is paying for. Founded by the team that scaled Gojek and backed by Peak XV Partners (formerly Sequoia India & SEA) and RTP Global.
Our platform, Exo, powers the entire delivery operation. It ingests client documentation, codebases, and requirements within hours, compressing weeks of traditional discovery into days, then works alongside our teams to deliver production-ready solutions. We've delivered production-ready solutions in days that traditionally take months. The methodology behind this is Real Agile, built specifically for how IT services works in the AI era.
We hire for judgment, because everything that doesn't require it is already automated. What's left is the job.
As a Lead - Forward Deployed Engineer at realfast.ai with 7–10 years of software engineering experience, you will lead the end-to-end lifecycle of high-complexity projects. A battle-tested engineer who can code like hell, understands what makes businesses tick, and can elevate an entire team while doing it.
You'll lead a team of Forward Deployed Engineers on client projects, working hand-in-hand with AI Transformation Leads to deliver software and products that help clients achieve their business goals. You'll own high-complexity projects end-to-end — driving product and technical design, navigating trade-offs, and ensuring timely delivery that upholds our standards of innovation and excellence.
This is a natural career progression from the FDE role. Like FDEs, you'll be deeply embedded in client work — but you'll also bring back learnings, patterns, and insights that have a significant impact on the platform we're building.
