[Hiring] Senior Back End Software Developer @CoLab Software

Role Description

We’re hiring a Senior Back End Developer to join our Build Viewing team—focused on a new product offering with a heavy data component at its core. You’ll be the sole back end developer on this team. That’s intentional. You won’t be handed neatly scoped tickets or wait on someone else to define the architecture—you’ll own it.

This role is about building the systems that make complex engineering data usable, fast, and reliable. You’ll design and implement services in Python, model and optimize data in Postgres, and work closely with frontend engineers to bring entirely new workflows to life.

A typical week might include:

• Designing a data model to support large-scale design datasets
• Debugging a performance bottleneck that only appears under real customer load
• Pushing back on a proposed approach because you see a simpler, more scalable path

This is not a maintenance role. You’re building something new, where the right technical decisions early will matter a lot later.

Qualifications

• 7+ years of backend development experience in a production environment
• Strong experience with Python and relational databases (Postgres preferred)
• Proven ability to design data models and optimize query performance
• Experience building and maintaining APIs for data-heavy applications
• Comfortable owning systems end-to-end, from design through production
• Experience with writing robust unit tests

Requirements

• You like being the person others rely on for backend decisions—and you take that responsibility seriously
• You’re comfortable working with ambiguity
• You care about data—how it’s structured, queried, and scaled
• You’ve felt the pain of bad schemas or slow queries, and you know how to avoid them
• You won’t thrive here if you need tightly defined specs, heavy oversight, or a large backend team to lean on day-to-day
• This role requires autonomy and strong technical judgment
• If the idea of owning a critical part of a new product—without a safety net—sounds energizing, you’ll likely do well here

Benefits

• Full-time, permanent position with competitive compensation and stock options
• Extended health benefits, unlimited paid vacation, and RRSP matching
• Remote-first, with flexibility to work from anywhere in Canada

Equity Note
