Titles matter less than the work you've done, but you'll need to bring: * Experience shipping customer-facing AI or LLM products into production * Strong Python engineering experience, alongside the ability to work across a wider product stack * A clear, structured approach to solving unfamiliar technical problems * Genuine curiosity around agent frameworks, models and new approaches within applied AI * The judgement to balance fast iteration with reliability, quality and maintainable systems * Strong communication and the confidence to challenge ideas constructively, As our Senior AI Engineer, you will own and evolve our agent architecture. This role goes beyond model-tuning; you'll work across our full stack, including Python backend services and React/TypeScript interfaces, to ship features that are reliable, useful, and responsive. We need a builder who is comfortable owning the full customer experience, not just the model layer, to transform how enterprise teams work., * You have strong commercial software engineering experience, likely gained over at least four years. * You have shipped customer-facing AI, LLM or agentic products into production. * You are a strong Python engineer and can build reliable production services, not just prototypes or notebooks. * You are comfortable contributing to React and TypeScript applications when the product requires it. * You have worked with areas such as agents, tool use, RAG, retrieval, context engineering, memory or AI evaluation. It would also be useful if you have: * Experience as a founding or early-stage engineer * Built an AI product or technical project from scratch * Worked with LangChain, Deep Agents, OpenAI or Anthropic models * Shipped AI systems used by a meaningful number of customers * Personal AI or engineering projects that show genuine technical curiosity ## Description Our AI agent is the core of MyTender, powering how our customers write, analyze, and manage complex enterprise bids. We aren't just connecting APIs; we are building a high-impact intelligence layer that is central to every customer workflow., * 0-30 days: You are up to speed on our product workflows, shipping initial improvements, and identifying key technical opportunities. * 30-60 days: You are owning core features of the agent, improving performance metrics, and shipping impactful updates to production. * 6 months: You have significantly advanced the quality and reliability of our AI, setting the technical direction for applied AI at MyTender., Own and Advance the AI Agent * Take technical ownership of our agentic AI architecture and its continued development. * Build new tools, skills and workflows that give the agent broader and more useful capabilities. * Improve the agent harness, orchestration and decision-making across complex bid workflows. Improve AI Quality and Performance * Build practical evaluation and measurement into the development process. * Develop ways to understand where the agent performs well, where it fails and how changes affect quality. * Improve context engineering, retrieval, bid-level memory and organisation-level memory. Ship Across the Product * Build and maintain production Python services supporting AI and product workflows. * Contribute to polished React and TypeScript product experiences where required. * Develop streaming interfaces and context-aware AI features that feel responsive and straightforward to use. Work Closely With Customers and Founders * Work directly with our founders, product lead and founding engineer. * Use customer feedback to understand the underlying problem before deciding what to build. * Break complex problems down from first principles rather than jumping immediately to a familiar solution. * Release in small, useful iterations where possible, with larger architectural work delivered deliberately. Help Raise the Engineering Bar * Contribute to architecture decisions as the product and customer base grow. * Write clear, maintainable and well-tested code. * Give thoughtful PR feedback and take part in technical discussions across the team. ## Related Videos - [On a Secret Mission: Developing AI Agents](https://www.wearedevelopers.com/videos/1510-on-a-secret-mission-developing-ai-agents) - [Do TypeScript without TypeScript](https://www.wearedevelopers.com/videos/327-do-typescript-without-typescript) - [Watch Tests Go Brrrr! : Getting Started with Cypress in ReactJS](https://www.wearedevelopers.com/videos/282-watch-tests-go-brrrr-getting-started-with-cypress-in-reactjs) - [Developing the Backend with Stefan Lingler, CTO at Shpock](https://www.wearedevelopers.com/videos/100360-developing-the-backend-with-stefan-lingler-cto-at-shpock) - [Nest.js - TypeScript in the backend can also be clean](https://www.wearedevelopers.com/videos/1033-nest-js-typescript-in-the-backend-can-also-be-clean) - [Meet Your New BFF: Backend to Frontend without the Duct Tape](https://www.wearedevelopers.com/videos/682-meet-your-new-bff-backend-to-frontend-without-the-duct-tape) ## Related Articles - [How to Become an AI Engineer](https://www.wearedevelopers.com/magazine/331-how-to-become-an-ai-engineer) - [Navigating the AI Shift](https://www.wearedevelopers.com/magazine/629-navigating-the-ai-shift) - [What is Agentic Programming and Why Should Developers Care?](https://www.wearedevelopers.com/magazine/625-what-is-agentic-programming-and-why-should-developers-care) - [From Prototype to Production: Build AI Agents with This Free 4-Course Learning Path](https://www.wearedevelopers.com/magazine/655-from-prototype-to-production-build-ai-agents-with-this-free-4-course-learning-path) - [What is Software Engineering in the Age of AI?](https://www.wearedevelopers.com/magazine/640-what-is-software-engineering-in-the-age-of-ai) - [Graph and AI Trends 2026: Why Is AI Running but Not Yet Delivering?](https://www.wearedevelopers.com/magazine/680-graph-and-ai-trends-2026-why-is-ai-running-but-not-yet-delivering)
