• Collaborate with product, engineering, and other cross‑functional colleagues to turn requirements into practical technical solutions.
• Stay current with AI and software engineering developments, applying relevant approaches to improve products and ways of working.

WHAT YOU’LL BRING

• 4+ years of hands‑on software engineering experience, with strong Python and backend/API development skills.
• Practical exposure to LLMs and GenAI, such as RAG, agentic workflows, or LLM integrations.
• Experience building cloud‑native solutions, ideally using AWS, CI/CD, and modern DevOps practices.
• Strong software design skills, with experience building reliable, maintainable, and scalable systems.
• Ability to solve complex technical problems and make sound trade‑offs across performance, security, and scalability.
• Experience working in Agile, product‑oriented environments and collaborating effectively across engineering and product teams.
• Curiosity about emerging AI technologies and enthusiasm for applying new approaches to practical engineering challenges.
