Staff Site Reliability Engineer

Job Overview

Application Tabs is the leading AI-native revenue platform for modern finance and accounting teams. Tabs agents automates the entire contract-to-cash lifecycle, including billing, collections, revenue recognition, and reporting, to help teams eliminate manual work and accelerate cash flow. High-growth companies like Cursor and Statsig rely on Tabs to generate invoices directly from contracts, reconcile payments in real time, and automate ASC 606 compliance.

About the Role

We’re looking for a Staff Site Reliability Engineer to lead the evolution of Tabs’ platform as we scale. In this role, you’ll operate as a senior individual contributor, partnering closely with engineering and product teams to design, build, and operate systems that are reliable, observable, and easy to develop on. You’ll own our infrastructure direction, shape how we ship software, and set the standard for operational excellence across the company. This is a high-impact role for someone who enjoys solving complex systems problems, influencing architecture, and raising the reliability bar without becoming a gatekeeper.

Key Responsibilities

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


• CI/CD systems with a strong emphasis on developer experience, safety, and automation (GitHub 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, postmortems, and the reliability culture that surrounds them

What You’ll Do

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


• Improve observability, alerting, and incident processes across services


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


• Partner with engineering teams to design resilient, scalable systems


• Build automation to reduce toil and lower operational risk


• Mentor engineers and influence best practices across teams

Required Qualifications

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 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
