At least 10 years' software engineering experience, with a track record of providing technical solutions to complex problems at scale.
Experience developing an AI / ML product is highly desirable — familiarity with the realities of shipping AI features, agents or model-backed products.
Solid backend Java and experience with Spring framework; ideally full-stack (≈***** backend/frontend) with TypeScript and React front end.
Backend essential, frontend nice-to-have.
Python exposure valuable given our model-backed components; comfort working alongside data scientists and ML workflows.
Experience across on-prem and SaaS/cloud delivery (Docker, Kubernetes, Helm, AWS) is desirable.
Experience building or integrating AI/LLM-backed features, agents or agentic workflows is highly desirable.
Familiarity with NLP,



document intelligence or data-enrichment technologies (or adjacent) is a strong plus.
Hands-on and strategic, a strong communicator and consensus builder, comfortable operating across multiple teams and tech stacks and driving clarity in ambiguity.
