Job description

At OnSite, we’re building the intelligent work chat platform for field teams.

The people building and maintaining the physical world still coordinate much of their work through group chats and paper files. Important updates get buried, schedules fall behind, records get lost, and admins spend countless hours performing manual data entry.

We’re building a better way for field teams to work. OnSite brings humans and AI together in the same conversations, turning everyday chats into project tracking, reporting, and planning. We’re building agents that understand what’s happening across the team, keep everything on track, and handle the busywork so teams can focus on what matters.

We’re backed by Tin Men Capital, Alter Global, Hustle Fund, and Gondor Capital.

About the Role

We’re looking for a junior-to-mid-level QA engineer with strong testing fundamentals, coding ability, and an interest in building better ways to test software.

You’ll help keep our mobile and web apps reliable through hands‑on testing, automated checks, and AI-assisted QA. Alongside investigating bugs and verifying releases, you’ll build testing tools and workflows that help the team catch problems earlier and reduce repetitive manual work.

You should be methodical, curious about how software works, and comfortable digging into code and logs to understand what went wrong.

What You’ll Be Doing

• Test mobile and web. Apply QA best practices to plan coverage, explore edge cases, and run regression checks before releases.


• Build testing automation. Develop reliable automated tests and reusable tools, and integrate them into CI/CD with engineers.


• Use AI in QA. Build AI‑assisted testing workflows and help evaluate our agents’ responses, actions, and permissions.


• Investigate bugs. Use logs and monitoring tools to diagnose issues, write clear bug reports, and verify fixes.


• Improve release quality. Communicate risks, maintain test coverage, and turn recurring failures into repeatable checks.

What We’re Looking For

• Strong QA fundamentals. You understand test design, exploratory testing, regression testing, and the bug lifecycle. You can decide what needs testing and when to use manual checks or automation.


• Practical interest in AI-assisted QA. You’ve experimented with AI tools for coding or testing and can explain how you checked their output. You’re keen to build useful automation into your everyday workflow.


• Attention to detail and clear communication. You can isolate issues, explain them precisely, work independently on defined tasks, and flag uncertainty or blockers early.

Nice to Have

• Experience testing mobile apps on both iOS and Android.


• Experience integrating automated tests into CI/CD pipelines.


• Experience with automation tools like Playwright, Cypress, Maestro, Appium, or Detox


• Familiarity with Sentry, AWS CloudWatch, Datadog, Grafana, or New Relic.


• Experience testing chat apps, real‑time systems, or AI agents.


• Experience building testing utilities, test data generators, or AI‑driven testing workflows.


• Firsthand experience in field operations, or testing software for deskless teams.

How We Work

We’re a small team that works hard, ships fast, and cares deeply about what we’re building. Everyone is expected to take ownership of problems and see them through.

You’ll work closely with the rest of the engineering team to improve both the product and how we test it. We value thoughtful questions, clear evidence, and people who turn problems into better tools and processes.

Why Join

You’ll help make software dependable for people whose jobs happen away from a desk. From a missed notification to a failed upload, the details you catch can make a real difference to someone’s working day.

As an early hire, you’ll gain hands‑on experience across mobile, web, automation, and AI testing, with room to take on more responsibility as you grow. We offer competitive salary and meaningful equity.
