Infrastructure Engineer

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.

We're looking for a Staff Infrastructure Engineer to own the foundation Tabs runs on: our AWS environment, how we ship software, and how we know when something is wrong. You'll set infrastructure direction for the company as a hands-on individual contributor, partnering with our platform team, our product engineers, and the product teams who build on what you build.

Tabs is building, not maintaining. We're at the point where infrastructure is becoming a real investment area, and the decisions made in this seat will shape how the whole engineering org ships for years. Payments, billing, and revenue for high-growth companies come with real compliance requirements. The goal is to build it correctly, keep it easy to maintain, and evolve it as we grow.

This is not a corner seat. You'll be expected to shape engineering and product decisions, and you'll have engineering leadership that understands infrastructure work and will pressure-test your calls. You won't be working alone: you'll own the outcomes, with high-caliber engineers around you.

• AWS infrastructure direction and platform evolution, including the migration from ECS/Fargate toward a more modern, scalable platform

• Infrastructure as code and container foundations, with Terraform and Docker at the core

• CI/CD systems with a strong emphasis on developer experience, safety, and automation (Git Hub Actions today; maturing CD tomorrow)

• Ephemeral environments and preview deploys to speed iteration and increase confidence in changes

• Observability standards across metrics, logs, and tracing, including alert hygiene, dashboards, and SLO development

• Incident response, on-call, postmortems, and the reliability culture that surrounds them

• Define and evolve reliability standards, SLIs, SLOs, and error budgets

• Improve observability, alerting, and incident processes across services

• Lead high-severity incidents hands-on and drive clear, actionable follow-ups

• Partner with engineering teams to design resilient, scalable systems

• Write production-quality code and automation to reduce toil and lower operational risk, so repeated problems get solved once

• Mentor engineers and influence best practices across teams

• You're a software engineer first, and your infrastructure expertise is built on that foundation

• You've run production systems on AWS and can lead platform-level change

• You think in systems: risk, rollback strategy, blast radius, and feedback loops

• You treat CI/CD and environments as products that should be fast, reliable, and self-serve

• You dig into logs and data yourself when something breaks, especially under pressure

• You influence through trust and clarity rather than control

• You balance pragmatism with long-term system health

• You value learning from failure and improving processes over assigning blame

• You communicate clearly and work well across teams

• 8+ years in software engineering, infrastructure, or SRE roles

• Experience in one or more modern languages such as Type Script, Python, or Rust with a track record of writing production-quality scripts, tools, and services, and still hands-on today

• Deep hands-on experience running production workloads on AWS, including container platforms such as…
