ABOUT BASETEN Baseten powers mission-critical inference for the world's most dynamic AI companies, like Cursor, Notion, OpenEvidence, Abridge, Clay, Gamma, and Writer. By uniting applied AI research, flexible infrastructure, and seamless developer tooling, we enable companies operating at the frontier of AI to bring cutting-edge models into production. We're growing quickly and recently raised our $1.5B Series F https://www.baseten.co/blog/announcing-our-series-f/, led by Altimeter Capital, Conviction Partners, and Spark Capital. Join us and help build the platform engineers turn to ship AI products. THE ROLE As a Software Engineer on the Internal Tooling team, you will own the internal operating system that sits at the heart of how Baseten operates. Capacity helps unlock revenue by carefully balancing supply and demand. The operating system manages all aspects of the customer lifecycle: from onboarding to managing complex customer SLA requirements. This role is for engineers who want to own a product end to end, not just implement tickets. You will work directly with the Capacity, Sales, and Engineering teams to understand requirements, define solutions, and ship software that removes friction from some of the most high-stakes workflows in the company. If something is slow, manual, or error-prone in the capacity fulfillment lifecycle, you will be the one to fix it. You are a strong fit if you have strong product intuition, move fast without sacrificing quality, and take satisfaction in building tools that make the people around you measurably more effective. RESPONSIBILITIES - Own the Capacity product end to end: scoping, design, implementation, and iteration based on feedback from internal stakeholders - Translate complex operational requirements from Capacity, Sales, and SRE teams into clean, ergonomic product experiences - Build and maintain full-stack features across the Capacity toolchain, including UI surfaces, APIs, and backend services - Identify workflow bottlenecks and manual processes across the capacity lifecycle and drive their elimination through tooling - Instrument your work with observability and monitoring so issues surface before they become incidents - Partner with SRE and Infra teams to ensure Capacity reflects the operational reality of the fleet, not just the desired state REQUIREMENTS - Bachelor's degree or higher in Computer Science or a related field - 5+ years of software engineering experience, with meaningful time spent owning a product or internal platform end to end - Strong full-stack proficiency; experience with NextJS, JavaScript, Postgres / Drizzle, Tailwind and AWS. Experience with SST.dev http://SST.dev is a plus but not a requirement - Demonstrated ability to work directly with non-engineering stakeholders to understand requirements and translate them into product decisions - Experience building internal tooling, operational platforms, or developer infrastructure — particularly in high-growth or infra-heavy environments - High ownership mindset: you notice what is broken, you fix it, and you follow through - Interest in AI/ML infrastructure; familiarity with GPU infrastructure, or capacity planning is a meaningful plus BENEFITS - Competitive compensation, including meaningful equity - (U.S. only) 100% coverage of medical, dental, and vision insurance for employee and dependents - Flexible PTO policy including company wide Winter Break (our offices are closed from Christmas Eve to New Year's Day!) - Paid parental leave - Fertility and family-building stipend through Carrot - (U.S. only) Company-facilitated 401(k) - Exposure to a variety of ML startups, offering unparalleled learning and networking opportunities.
