Company mission
The leading composable commerce platform that arms you with the essential tools to evolve, build, and scale at your own pace
Role
Who you are
- You're a creative problem-solver who is wired to find solutions. You confidently dive into complex challenges and have a talent for making them simple for others. Your curiosity drives you to constantly grow and contribute to an environment of trust and teamwork. Great ideas come from many paths, and your unique perspective matters more than checking every box. What matters most is the mindset you bring to the work
- Shipped full-stack apps to production and owned them end-to-end: frontend through backend to deploy and operate, not handed off at a layer boundary
- 5+ years shipping production software, 2+ building with LLMs in production (real users, not demos)
- Hands-on experience with UI protocols (A2UI, AG-UI, MCP-UI, or similar). You've built against a generative/agent-driven UI protocol, not just consumed a REST API
- The AI spine: prompt/context engineering, agents, tool use, structured outputs, evals, MCP Python and TypeScript/Node + React; comfortable with async, streaming, and observability
- Working fluency with retrieval/embeddings and SQL
Desirable
- Fine-tuning/distillation, e-commerce or marketplace systems, and a track record in 0→1
What the job involves
- You own AI capabilities end-to-end: from the data and context that feed a model, through agent orchestration, to the generative UI a user sees and trusts
- You've personally shipped and operated full-stack apps in production, so backend, frontend, data, and ML aren't four teams you coordinate with, they're four things you do. You're not a research scientist; you wield models and engineer ruthlessly around their uncertainty
- Build agent loops and orchestration: tool use, structured outputs, business-rule enforcement, graceful failure
- Build the integration layer (via MCP) that lets agents securely call backend systems and business APIs
- Render model output into live, streamed, accessible UI via generative-UI protocols
- Ground models in real data: retrieval, embeddings, and feedback loops that actually close
- Treat evals as a first-class system - provable improvement, not vibes
- Take a capability from prompt-in-a-notebook to a measured, guard-railed production feature
Salary benchmarks
Our take
eCommerce software simplifies complex processes and helps companies effectively manage their inventory, calculate taxes and perform other business-related functions. While companies like Shopify have addressed the needs of smaller retailers, commercetools has built its business around catering to enterprises' specific needs and large investment budgets.
The company provides APIs that can be used to build customised payment, check-out, social commerce, marketplace and other services. It powers billions of sales annually for its customers, which have included Audi, AT&T, Danone, Tiffany & Co., and John Lewis.
In 2021, commercetools acquired the frontend platform, Frontastic, to build a broader portfolio of commerce technology services. In 2023, commercetools scaled the availability of its tools in mainland China, marking the first cloud-native commerce solution to ever expand into the country, a significant expansion, seeing as the nation is the largest single eCommerce market worldwide. Though it now faces more competition in the form of Shopify and other growing competitors - as well as the threats of international tariffs, commercetools continues to innovate in the headless commerce space.
