This unique value is leading to unparalleled growth; in 2025, we tripled our ARR at scale. Why join Handshake now: Shape how every career evolves in the AI economy, at global scale, with impact your friends, family and peers can see and feel Work hand-in-hand with world-class AI labs, Fortune 500 partners and the world's top educational institutions Join a team with leadership from Scale AI, Meta, xAI, Notion, Coinbase, and Palantir, among others Build a massive, fast-growing business with billions in revenue About the Role As a Senior Software Engineer on Operating Tooling, you'll build internal products and automation that help Handshake's operators run the business at high quality and speed. This team functions like an embedded/consulting engineering group: you'll partner directly with operators, learn their workflows deeply, and deliver pragmatic solutions that remove friction, improve quality, and enable new operational capabilities. This role is highly collaborative and communication-heavy. Success requires strong technical fundamentals plus high EQ-someone who can translate ambiguous operational needs into reliable systems, and iteratively ship improvements that stick. In this role, you will: Embed with operators to understand processes, pain points, and success metrics; translate them into clear technical requirements and deliverables. Architect and build internal tools, automations, and workflows that improve operational throughput, accuracy, and visibility. Lead projects end-to-end: discovery, scoping, technical design, implementation, rollout, and iteration. Balance speed and quality by making thoughtful tradeoffs, ensuring maintainability, and building with operational reliability in mind. Collaborate closely with cross-functional partners (operators, engineering, product) to drive adoption and measurable impact. Mentor other engineers and help establish strong engineering practices for an internal-tools environment. Desired Capabilities 5+ years of software engineering experience, with comfort owning systems end-to-end (from requirements through production support). Strong communication skills and stakeholder management; able to partner deeply with non-engineering teams and operate with high empathy/EQ. Experience building internal tools, workflow systems, or automation for operations-heavy teams (or analogous customer-embedded roles like FDE / solutions engineering). Strong engineering judgment: can design scalable systems, pick the right level of abstraction, and avoid over-building. Track record of delivering iterative, high-leverage improvements in ambiguous environments. Extra Credit Experience with workflow/backlog systems, intake processes, and operational analytics (instrumentation, dashboards, QA). Comfort operating in a "player-coach" environment (mix of hands-on building plus lightweight coordination/mentorship as the team grows). Background building tooling for knowledge-work operations (e.g., case management, review/approval flows, data quality tooling).
