Overview:
We're looking for a Senior Software Engineer to own the layer that determines whether Pathfinder scales: multi-agent execution orchestration and cross-platform execution caching. This is the kind of person who treats an LLM rate limit not as a blocker to escalate but as a system design problem to solve — someone fluent in building with AI, not just building AI features, who can reason about agentic execution patterns, cost/performance tradeoffs, and orchestration architecture with no existing playbook to reference. You'll be hands-on 80-90% of the time, architecting and shipping the infrastructure that lets autonomous agents run reliably at scale, while setting technical direction for a small team solving problems nobody has solved before.
This role suits a builder — someone who prototypes quick, is comfortable being wrong in week one and right by week three, and treats ambiguity as the engaging part of the job rather than a reason to wait for more clarity.
- Responsibilities
- Design and build the multi-agent execution orchestration and cross-platform execution-caching infrastructure that Pathfinder's scale and LLM cost efficiency depend on
- Drive significant technical initiatives end-to-end, from functional requirements through technical specification, test planning, and production rollout
- Generate technical documentation that communicates architectural and design tradeoffs clearly to both engineering teams and business stakeholders
- Resolve defects across QA, pre-production, production, and post-release patches for a system running 1M+ E2E test executions
- Work cross-functionally with product management, QA/QE, and partner teams (18+ teams currently building on Pathfinder) to unblock their adoption and surface platform gaps early
- Operate in Agile/Scrum cadences while retaining the independent judgment to make calls the backlog hasn't anticipated yet
- Qualifications
- Bachelor's degree in Computer Science, Engineering, or equivalent practical
