The OpportunityWe're looking for an Engineering Manager to lead the Formula Engine team within Superhuman Docs. This is an opportunity to own the computational backbone that powers millions of distinct user-built applications — the formula system that glues data together across every building block in the platform.Superhuman Docs is where teams build living documents that replace scattered spreadsheets, project trackers, and internal tools with a single, flexible surface. At the heart of this experience is the formula engine — the system that lets users wire together tables, buttons, automations, and views into applications uniquely tailored to how they work. Every time a user writes a formula, they're programming their doc, and this team ensures that the program runs correctly, quickly, and at scale.The Formula Engine team owns the full vertical: the formula language and its grammar, the AST parser, the execution planner that determines what to compute and when, execution optimization that keeps millions of concurrent user applications responsive, the formula framework that other teams build on, and the performance infrastructure that makes it all work under real-world load. You'll lead a team of 5+ engineers solving problems that sit at the intersection of programming language design, query optimization, and distributed systems — all in service of an end-user experience that feels instant and intuitive.As an Engineering Manager on the Formula Engine team, you will:Lead and grow a team of 5+ engineers, providing mentorship, career development, and fostering a high-performance engineering culture.Own the technical direction for the formula engine — from language design and parsing through execution planning, optimization, and runtime performance.Drive improvements to formula execution that keep millions of user-built applications responsive as document complexity and platform usage scale.Build and refine evaluation and benchmarking frameworks to measure formula performance, correctness, and reliability across real-world workloads.Shape the formula language itself — evolving its expressiveness and usability so users can build increasingly powerful applications without hitting walls.Collaborate cross-functionally with product, design, and platform teams to ensure the formula engine enables new Superhuman Docs building blocks and features.Balance foundational investments in the execution engine with pragmatic delivery — shipping incremental performance wins and language improvements while building toward a best-in-class computational platform.Define strategy for how the formula engine evolves as Superhuman Docs grows — anticipating the demands of new use cases, larger documents, and tighter integration across the Superhuman ecosystem.QualificationsHas 3+ years of engineering management experience leading teams of 5+ engineers, with a track record of hiring, developing, and retaining strong talent.Brings deep technical experience in at least one of: programming language implementation, query planning/optimization, compiler design, or high-performance runtime systems.Has shipped and operated systems at scale where correctness and performance are non-negotiable — computation engines, database internals, or developer platforms.Demonstrates strong instincts for performance engineering — profiling, benchmarking, and systematically eliminating bottlenecks in complex systems.Shows a track record of managing ambiguity — defining strategy, making tradeoffs, and shipping in fast-moving product areas where user needs evolve quickly.Communicates clearly and influences effectively across engineering, product, design, and leadership.Is energized by the challenge of building the invisible engine that makes a product feel magical — where success means users never think about performance because everything just works.We invite you to share your knowledge, experience, and goals with us to help us find the best team match for you.
