AI Engineer

We are hiring a remote AI Engineer with 2 or more years of software experience to build LLM features, agent workflows and the evaluations that show they work, in client projects and our own products.

What you will do

• Build LLM features into products: drafting, summarising, pulling structured data out of messy text, and assistants that call tools.
• Build agent workflows with clear limits: which tools they can use, what they may spend, and human review before anything public or irreversible.
• Write evaluations: test sets built from real cases, regression checks before a prompt or model change ships, and numbers for accuracy, speed and cost.
• Pick the right model for each job, route requests across providers with fallbacks, and keep costs predictable.
• Use retrieval (RAG) where it helps, and say so when plain search or a simple rule would do better.
• Fine-tune and run small open models when privacy or speed means the data should stay on the device.

What we look for

• 2 or more years as a software engineer, in Python or TypeScript (ideally both).
• At least one LLM feature you shipped to real users, and an answer to “how did you know it worked?”
• Evaluations as a habit: you measure before and after a change.
• A clear view of the failure modes, such as made-up answers, prompt injection and data leaks, and designs that work around them.
• Care with personal data: it goes only where it should.
• Clear written English.

Good to have

• Fine-tuning (for example LoRA)
• On-device inference (llama.cpp, GGUF, MLX)
• Model Context Protocol (MCP)
• PostgreSQL with pgvector

How we work

• Written scope first. Every piece of work starts with a short written scope: what ships and when.
• Weekly demos. We show progress on a live link every week, to each other and to clients.
• A direct line. You talk to clients and to our founder directly. There is no account layer in between.
• Remote and written. We work remotely and write things down: decisions, handovers and runbooks. Expect a few hours a week of overlap with India time (UTC+5:30) for demos and reviews.

How to apply

Email careers@roundrobin.in with "AI Engineer" in the subject line, and send:

• A link to an LLM project you built (repository, demo or write-up), and how you evaluated it.

• A short note on a failure you found in an LLM system and how you fixed it.

• Your CV or LinkedIn profile, your time zone, and when you could start.

• We read and reply. We read every application and reply to each one, including when the answer is no.

• A conversation. If there is a fit, a call of about 30 minutes about work you have done.

• A clear answer. We decide and tell you either way. We never charge applicants anything.
