Senior AI Engineer

Small team, big scope. You'll be one of the first AI hires at TCS, shaping architecture, hiring bar, and the roadmap. Equity is meaningful.

As a Senior AI Engineer at TCS, you'll join a small, senior team building AI-native healthtech products from the ground up. You'll work daily with Replit, ChatGPT, Lovable to design, ship, and scale features that customers use every day. This is a high-ownership role — you'll have direct input on what we build and how we build it.

• Own the full lifecycle of features — from spec, prototype, A/B test, to rollout
• Lead architectural reviews for new HealthTech initiatives
• Instrument observability — eval pipelines, prompt versioning, cost dashboards
• Write clean, well-tested code in Python / TypeScript and review PRs from peers
• Design, build, and ship production-grade AI features using Replit, ChatGPT, Lovable
• Mentor junior builders and contribute to engineering standards

• Experience with prompt engineering, evals, and prompt-versioning workflows
• Solid understanding of REST APIs, webhooks, queues, and event-driven design
• Bachelor's degree in CS, Engineering, or equivalent hands-on portfolio
• Comfort working with vector databases (pgvector, Pinecone, Weaviate)
• Have shipped LLM-powered products to real users (not just prototypes)
• 2–4 years of experience as a Senior AI Engineer or in a closely related role
• Strong written communication — you can document decisions clearly

• Familiarity with Cloudflare Workers / serverless edge runtimes
• Have written publicly (blog posts, talks, OSS) about AI engineering
• Built and operated agentic systems in production
• Open source contributions to AI / dev-tools projects

• Work on problems that genuinely move the needle in HealthTech
• Direct ownership — your code reaches real users within days, not quarters
• Learn from a team that has shipped at scale and built with Replit, ChatGPT, Lovable from day one
• Tiny team, big surface area — wear multiple hats and grow fast
