Handshake AI supports all of the frontier AI labs, working on their most complex data at the largest scale.
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 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).

Vertical Order Traversal Perform a vertical order traversal of a binary tree. Input: root = [1,2,3,4,5,6,7] Output: [[4],[2],[1,5,6],[3],[7]] Explanation: Traverses the tree maintaining column indices, seamlessly grouping nodes that share the exact same vertical alignment.
codingmedium - 3
Diameter of a Binary Tree Find the diameter of a binary tree. Input: root = [1,2] Output: 1 Explanation: The longest path is simply the single edge connecting the root node to its only child.
codingmedium - 4
Clone an Undirected Graph Clone an undirected graph. Input: adjList = [[]] Output: [[]] Explanation: Creates a new, deeply cloned graph containing only one single node with zero connected neighbors.
codingmedium - 5
Valid Word Abbreviation Determine if a string matches a valid word abbreviation. Input: word = "apple", abbr = "a2e" Output: FALSE Explanation: The abbreviation claims exactly 2 characters are skipped between 'a' and 'e', but "ppl" is actually 3 characters long.
