Full Job Description

**About the team:** You’ll run a small group inside our R&D function whose mission is to validate new product bets quickly. We move from “is this worth building?” to a working prototype in weeks, not quarters. You set the research direction, decide what to build and how, and lead the team to get it in front of users and stakeholders fast. This is a builder-leader role: roughly hands-on coding alongside the team, with the rest spent on strategy, planning, and unblocking people. **What you’ll do:** * Own the technical vision and execution for a portfolio of PoCs, from initial research through working prototype. * Lead a small engineering team — set direction, review work, grow people, and keep the group focused and motivated. * Run lightweight research: scope a problem, survey the landscape, form a hypothesis, and define what a successful prototype must prove. * Translate fuzzy ideas into concrete plans with clear milestones, then execute against them. * Build fullstack — backend services, frontends, data pipelines, and the glue between them. * Work AI-first: use AI tooling to accelerate development, and build products that embed LLMs, agents, retrieval, and related techniques where they create real value. * Make pragmatic build-vs-buy and “good enough for a PoC” calls, balancing speed against the parts that need to be solid. * Partner with product, design, and leadership to decide which bets graduate from prototype to product. **What we’re looking for:** * Proven technical leadership — has led a team or owned a major workstream, set technical direction, made the call on what to build, and shipped through others. You can run lightweight research, turn a fuzzy idea into a plan with clear milestones, and keep a small group focused and motivated. (Formal management title not required; the instinct and track record are.) * Strong fullstack engineering with real AI-building depth — production experience across backend and frontend in at least two of C#, Python, and JavaScr
