AI Engineer — Vertexcover Labs
Who We Are
Vertexcover Labs is an employee-focused, engineer-run software studio. We partner with fast-growing, funded startups around the world—Rephrase.ai, Dhiwise, Dunzo, Dubdub, Xapo, Arintra etc.—to crack their toughest engineering problems. Everyone is an individual contributor; no management layers. Engineers choose the projects they work on, see each project's P&L, and share directly in the profits.
Whether it's building multi-agent systems for production, scaling ML pipelines across GPU clusters, or shipping RAG-powered products that end-users rely on—we solve hard AI problems for real companies.
A Few Problems We Are Currently Working On
- AI Agents Test-authoring agents that convert natural language into e2e tests.
- Ad-performance agents that learn what works for your brand and generate winning creatives automatically.
- Scale + MLOps Optimise ML pipelines and fix autoscaling by applying queuing theory while juggling CPU / GPU memory contention.
- RAG & Knowledge Systems Design and deploy retrieval-augmented generation pipelines—chunking strategies, embedding models, reranking, and evaluation loops.

- Strong in at least one other language (Python, Go, Rust, TypeScript, Java …); happy to learn more.
- First principle understanding of how LLMs, embeddings, vector databases and AI Agents work
- Evidence of shipping real AI-powered software—OSS, side projects, or production features.
- Comfortable navigating the fast-moving AI landscape—papers, new model releases, evolving APIs.
