Senior Product Engineer

Job description

About Shortcut Our mission is to ensure software development teams can do their best work. Shortcut is the project management platform that teams actually want to use: fast, intuitive, and lightweight enough to stay out of the way while keeping everything moving. We’re deliberately focused on what software teams actually need. Where other tools accumulate configuration sprawl, admin overhead, and features built to check enterprise boxes, we keep Shortcut simple, opinionated, and fast. That focus is a product decision we make every day, and engineers here are expected to defend it. We bring issue tracking, sprints, and roadmaps together in one place, built for the way modern engineering teams actually operate. With Korey, our agentic AI layer, we're going further, automatically surfacing context, structuring work across tools, and keeping teams in the loop on what matters, whether the work is done by people or agents. We believe the future of software development is people and agents working together, and we’re building Shortcut and Korey to be the place where that work happens: one platform where humans and agents plan, track, and ship side-by-side. We’re a remote-first company with a lean, experienced team. We move fast, trust people to make good calls, and communicate openly. We care about the craft of what we build, and we think software that’s genuinely enjoyable to use is worth the effort it takes to get there. The Role We're a product development team where everyone ships. You should be excited to work as a full-stack Product Engineer, not just a software developer. An engineer is the Directly Responsible Individual for every project we ship, with support from fellow engineers and the Product and Design teams. This role sits at the center of how we build agentic, LLM-powered features. You’ve built, deployed, maintained, and improved agentic products with LLMs at the core. You geek out in the weeds analyzing user interactions, implementing fixes at the appropriate layer and measuring the outcomes, continuously improving your eval harness, and incorporating human and LLM-based judgments. You’ve designed scalable architectures for these systems: retrieval, agents and their lifecycles, models, tool calls, and state management across contexts. How We Work We’re building the project management platform for software teams and their agents, and we work that way ourselves. Agentic tools are part of everyday engineering at Shortcut: we expect you to use them alongside your expertise and experience as an engineer to plan, build and ship. This part of our industry is evolving fast, and we support engineers with dedicated funds and time to learn, experiment, and share best practices as a team. The craft here is moving up the stack: less mechanical execution, more architecture, product thinking, and judgment about what to build. What You’ll Do Full-stack web application development using TypeScript/JavaScript on top of Zero Architect and implement customer-facing, LLM-based application layers Design APIs for human and agent consumption Evaluate and iterate on models, prompts, and eval pipelines to balance quality, latency, and cost Take turns as the on-call engineer What We Build With TypeScript / JavaScript and Node Postgres AWS Zero (Rocicorp’s sync engine) Anthropic and OpenAI models powering Korey What You Bring 5+ years of professional experience building SaaS web applications, with hands-on experience incorporating agents and LLMs into production over the last 2+ years Professional experience building with TypeScript/JavaScript, Node, Postgres (or similar RDBMS), and AWS (or similar cloud platform) LLMs in production: You’ve built evals, observability, or safety guardrails for LLM systems Agent leverage: You use agentic coding tools daily, you know how to structure work so agents execute it well, and you rigorously verify what they produce Product taste: You dig into user problems, cut through ambiguity, and define clear outcomes before implementation begins Speed, in both senses: you’d rather ship and adjust course than wait for the perfect plan, and you keep pace with rapidly changing tools. You’ve built evals, observability, or safety guardrails for LLM systems Extra Credit Production experience with Zero or a comparable state-synchronization framework You enjoy writing or speaking publicly about what you learn; we’ll give you the platform if that’s your thing Benefits & Perks Compensation 150k-195k Equity, giving you real ownership in what we're building Time Off Flexible, open vacation policy — take the time you need Company holidays, plus paid safe & sick days and volunteer PTO days Generous parental leave Learning & Development Annual learning stipend to spend on courses, books, or conferences Remote & Equipment Fully remote — we ship you the equipment you need to do your best work Generous home-office stipend to set up a workspace that works for you This role is remote within the United States, and the salary range listed reflects Shortcut's good-faith compensation expectations for this position. Final offers may vary based on experience, skills, and location. Candidates must be authorized to work in the United States. Shortcut does not currently sponsor employment visas for this role. This role requires a background check as a condition of employment, conducted in compliance with applicable federal, state, and local law. Shortcut is proud to be an Equal Opportunity Employer. We value diverse backgrounds and perspectives and provide accommodations upon request.
