The team is headquartered in New York and brings deep expertise in finance and AI.About the RoleTabs is looking for a Senior Software Engineer to join our Platform team, reporting to the engineering leader who owns platform and infrastructure. Your customers are the engineers around you. The work is measured by a single question: can the rest of engineering ship faster because of what you built?Platform at Tabs is deliberately understated. We are the first and last line of defense — the layer that makes deploys boring, failures legible, and the path from commit to production short. What you'll experience is real leverage: every improvement you make compounds across every team.You'll own the foundation every other engineer builds on: build systems, CI/CD, infrastructure, developer tooling, dev containers, and the API infrastructure and standards teams build against. A lot of this work lives outside any product roadmap. It's ours to define, and we set the bar for the rest of engineering. You'll also help shape what's next, like the internal platform-as-a-service we're planning to build. All of it supports a product that runs the contract-to-cash lifecycle for high-growth companies, where reliability is measured in real money. We move on two-week cycles, and the platform keeps up.How We OperateWe work hard. Two-week sprints, weekly ship goals, short feedback cycles. Built around intra-month product releases.We work smart. Get in front of the other engineering teams, use both data and customer feedback to drive decisions, while keeping the bigger picture in mind.We work together. In-office culture with people you want to work with. Lots of whiteboard space. Expense coffee, lunch, and dinner when in the office.What You'll DoOwn platform and infrastructure work that shortens the path from an engineer's commit to productionBuild and evolve the build systems, CI/CD, and developer tooling the whole engineering team relies on every dayImprove observability and operational tooling so problems surface early and are cheap to diagnoseMake hard tradeoffs on behalf of the wider engineering org, and explain the reasoning behind themPartner with product engineering teams to find out what's actually slowing them down, then go fix itWrite production-quality code and automation across the stack, not just at the infrastructure layerWho You AreYou get genuine satisfaction from solving other engineers' problemsYou'd rather build the thing nobody notices than the thing everyone seesYou dive deep instead of handing off, and you finish what you pick upYou make pragmatic calls under constraint and can defend themYou have no ego about it — this team operates as a teamExperience5+ years of professional software engineering experienceStartup experience is a must — you've owned broad surface area at a company moving through a growth stage, not one narrow specialty on a large, heavily staffed teamStrong hands-on experience with cloud infrastructure, CI/CD, and build toolingFluency in TypeScript, Python, or a similar modern language, with the judgment to write code others will maintainExperience operating production systems and reasoning about failure modesStrong foundation in computer science and codingPerks and Benefits (Full-time Employees)Competitive compensation and equityUnlimited PTOUp to 100% employer covered monthly healthcare premium (medical, dental, vision)Lunch provided via Sharebite, plus dinner for any later in office days.Parental leave up to 12 weeksTax free commuter and parking benefitsVoluntary insurances (Life, Hospital, Critical Illness, Accident)Employee Assistance Program (Rightway)Free One Medical Membership401kTabs is an equal opportunity employer.
