• Lead the design, evaluation, and deployment of our production photogrammetry pipeline — feature detection and matching, structure from motion, multi-view stereo, monocular depth estimation, mesh reconstruction, and the supporting infrastructure that makes them work at scale. • Drive integration and evaluation of newer 3D reconstruction approaches — gaussian splats, foundation 3D models (MASt3R / DUSt3R-class and successors), and what comes next — where they earn their place in the pipeline. • Optimize 3D systems for speed, accuracy, and robustness at production scale. • Use the right tool for the problem — classical 3D computer vision when it wins, learned approaches when they win. • Own the hardest technical investigations end-to-end — initial triage through production rollout and long-tail support. • Set the technical bar for photogrammetry on the team — review designs, raise the quality of experiments, codify what "great" looks like. • Own the production observability standard for photogrammetry — KPIs, instrumentation (metrics, logs, dashboards, alerts), and the processes that catch data-quality issues early and sustain performance at scale. • Mentor engineers on the team, then take on 1–2 direct reports in your first year and grow your scope over time as the sub-team expands. • Drive execution of the photogrammetry core roadmap in tight partnership with CV leadership. Translate strategic direction into shipped work, sequence it well, and call out when something isn't going to land in time to course-correct. • Codify debugging and investigation playbooks into reusable skills to empower the team and support the organization, minimizing escalations. • Reshape how the team uses AI across the SDLC — driving adoption of AI-first and prototype-first workflows and pushing the bar on what these tools should do for us. • Author reusable tooling that scales the team — agent skills, prompts, debugging playbooks, custom tooling — so other engineers (and our support org) can stand on your shoulders rather than escalate. • Run rigorous evaluations of AI tools — where they help, where they hurt, and how to tell. • Drive the adoption of prototype-first and AI-first development workflows. • Review agent-generated code with the same rigor as human-written code, and establish standards for trust and reliability. • Treat the AI tooling landscape as a moving target: actively track what's new, run it against current problems, and champion effective new tools across the team.
