Company mission
To empower engineering teams to build the future faster.
Role
Who you are
- You like being the person others rely on for backend decisions—and you take that responsibility seriously
- You’re comfortable working with ambiguity. There won’t always be a clear “right answer,” and you’re expected to move things forward anyway
- 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
- 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
- Frequently cited statistics show that people who identify with historically marginalized groups are likely to apply to jobs only if they meet 100% of the qualifications. We encourage you to help us break that statistic and apply even if you don’t meet every single qualification—your potential is what matters most to us
What the job involves
- 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, or 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
- Own the backend architecture for a new data-heavy product offering
- Design and implement services in Python that are reliable, scalable, and maintainable
- Model, query, and optimize complex datasets in Postgres
- Identify and resolve performance bottlenecks in data-intensive workflows
- Collaborate closely with frontend developers to shape APIs and user-facing functionality
- Make pragmatic tradeoffs between speed of delivery and long-term scalability
- Establish patterns and standards that future backend developers can build on
Our take
The mechanical design process requires lots of back-and-forth between engineers, designers and business stakeholders who are giving and acting on feedback. Getting everybody on the same page is time-consuming, and comes with lots of admin and flitting between different platforms, whilst important information slips between the cracks.
This is why CoLab has built a cloud-based platform for collaborative mechanical design and reviewing. It integrates into the existing stack of design and engineering teams to bring together all the teams involved in early-stage design. Basically, the platform pools data, feedback, tracking issues, emails, spreadsheets and notebooks into one collaborative space.
Ultimately, CoLab is a simple way to collaborate on concepts and projects at the planning stage, thus nipping in the bud any problems that could arise down the line. With an impressive series of investments behind it, the company plans to scale up its market push, explore the possibilities of AI and expand its team.
