About The Position

We are hiring a Senior Software Developer to join the One45 team. One45 is a core product at Acuity Insights, utilized by medical schools across North America for managing complex aspects of health professions education, including clinical placements, rotation scheduling, evaluations, curriculum management, learner records, and accreditation reporting. The product has a long history, supporting tens of thousands of users annually and is deeply integrated into institutional operations. This role involves both maintaining and improving the existing product while contributing to a significant modernization effort. The team is evolving APIs, enhancing data access and integrations, rethinking workflows, and incorporating AI-assisted tooling. This is a unique opportunity to join at a pivotal moment, influencing the product's evolution and the team's practices.

Requirements

Comfortable stepping into code you didn’t write, building context, and improving things without assuming they need to be rebuilt from scratch.
Ability to think in trade-offs, balancing technical quality, business needs, and the realities of a system serving real users.
Comfortable working across the stack, with a particular interest in understanding what happens beneath the surface (data movement, service interactions, production issues).
See testing and quality as part of the work itself.
AI is already part of how you work, using tools like Claude, Copilot, and Codex to learn faster, explore ideas, write code, and improve work.
Develop the judgment to know when to trust AI output and when to challenge it.
Take ownership, ask questions, surface concerns, contribute ideas, and don't wait for perfect clarity before taking the next step.
Care about outcomes, not just implementation.
Comfortable occasionally stepping in when the situation requires it for production system ownership.
Canadian residency and valid work authorization.
