Senior Software Engineer, Platform

Tabs is the AI Operating System for Revenue, built for modern finance and accounting teams. It combines deep revenue and accounting expertise with the agents and applications needed to run revenue work end to end. Tabs understands customer and contract context, applies accounting logic, and executes critical workflows with built in controls, auditability, and human oversight. With Tabs, finance teams can move from manually managing revenue workflows to directing outcomes while the system executes the work.

About the Role

Tabs 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 Operate

• We 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 Do

• Own platform and infrastructure work that shortens the path from an engineer's commit to production
• Build and evolve the build systems, CI/CD, and developer tooling the whole engineering team relies on every day
• Improve observability and operational tooling so problems surface early and are cheap to diagnose
• Make hard tradeoffs on behalf of the wider engineering org, and explain the reasoning behind them
• Partner with product engineering teams to find out what's actually slowing them down, then go fix it
• Write production-quality code and automation across the stack, not just at the infrastructure layer

Who You Are

• You get genuine satisfaction from solving other engineers' problems
• You'd rather build the thing nobody notices than the thing everyone sees
• You dive deep instead of handing off, and you finish what you pick up
• You make pragmatic calls under constraint and can defend them
• You have no ego about it — this team operates as a team

Experience

• 5+ years of professional software engineering experience
• Startup 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 team
• Strong hands-on experience with cloud infrastructure, CI/CD, and build tooling
• Fluency in TypeScript, Python, or a similar modern language, with the judgment to write code others will maintain
• Experience operating production systems and reasoning about failure modes
• Strong foundation in computer science and coding

Perks and Benefits (Full-time Employees)

• Competitive compensation and equity
• Unlimited PTO
• Up 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 weeks
• Tax free commuter and parking benefits
• Voluntary insurances (Life, Hospital, Critical Illness, Accident)
• Employee Assistance Program (Rightway)
• Free One Medical Membership
• 401k
