Why Join Us

The mortgage industry runs on legacy systems, slow processes, and information nobody can see. We are changing that by building better technology. nesto is a place for builders, problem-solvers, and curious minds – people who move fast, embrace innovation, and believe we're stronger together. This is the place for you if you trust your skills and want to build technology that reshapes an entire industry. An entrepreneurial culture built on trust, speed, uncomfortable ambition, being stronger together, and a relentless obsession with our clients. We also do not think building with AI belongs to engineers. Every function here is expected to automate its own repetitive work, and you will have support to do it.

Work Location and Time Zone

This is a remote-first role open to candidates anywhere in Canada. We strongly prefer candidates who can work Eastern Time hours. If you are based elsewhere in Canada and have worked Eastern hours before, we still want to hear from you.

Why This Role Exists

We're delivering major platform programs for our large enterprise partners. This role is focused on building automation coverage for these initiatives, shaping end-to-end quality as the programs scale.

We already have a strong automation suite and deep in-house expertise at the staff level. This is not a rebuild from zero. It's about taking what works, adapting it to a platform being reshaped for these programs, and wiring it into CI/CD so quality keeps pace with delivery speed. We move fast and iterate, but we don't ship manual workarounds – we invest in repeatable, scalable structure.

You'd be the automation specialist within our delivery team, working closely with our staff automation developers as expert sounding boards, setting the approach and advising us on how this should be done. You can expect roughly a 80/20 split between hands-on coding and collaboration, depending on the project stage.

What Success Looks Like

- Within 90 days, a working test automation framework is running, with 60–80% of critical test scenarios automated, running, and actively relied on by the team.

- Within six months, automation runs in the CI/CD pipeline on pull requests, mirroring what exists for our core platform.

- You've adapted and extended the existing automation framework rather than rebuilding from scratch – leveraging the suite and expertise already in place.

- You make sure quality is understood beyond sprint-by-sprint testing, with a focus on ensuring all the pieces work together end to end.

What You Will Be Doing

- Architect, build, and maintain scalable automated test suites in Playwright, using design patterns that keep them maintainable over time.

- Partner with architects, developers, product managers, and our Staff QA Automation Developers across the SDLC – to clarify requirements and define clear acceptance criteria early, and to raise QA practices across the organization.

- Drive quality across UI and API t
