About the client
The client is building a suite of SaaS products for websites—products with clear product-market fit, strong customer pull, and the potential to become $100M+ businesses.
As they grow, they need engineers who go beyond feature delivery. They are looking for backend developers who want to build enduring systems, make practical decisions, and help us ship great products with high velocity.
What You’ll Do
- Work with product, design, and support teams to turn real customer problems into thoughtful, scalable solutions.
- Design and build robust backend systems, services, and APIs that prioritize long-term maintainability and performance.
- Use AI-assisted tooling (where appropriate) to explore solution trees, accelerate development, and reduce toil.
- Improve velocity across the team by building reusable tools, abstractions, and internal workflows—not just shipping isolated features.
- Dig into problems deeply—whether it's debugging a performance issue, streamlining a process, or questioning a product assumption.
- Document your decisions clearly and communicate trade-offs with both technical and non-technical stakeholders.
What Makes You a Strong Fit
- You’ve built and maintained real-world software systems, ideally at meaningful scale or complexity.
- You think in systems and second-order effects—not just in ticket-by-ticket outputs.
- You prefer well-reasoned defaults over overengineering.
- You take ownership—not just of code, but of the outcomes it enables.
- You work cleanly, write clear code, and make life easier for those who come after you.
- You’re curious about the why, not just the what—and you’re comfortable contributing to product discussions
Bonus if You Have Experience With
- Building tools or workflows that accelerate other developers.
- Working with AI coding tools and integrating them meaningfully into your workflow.
- Building for SaaS products, especially those with large user bases or self-serve motions.
- Working in small, fast-moving product teams with a high bar for ownership.
How’s the team?
- Open and flat hierarchy
- High-agency work with a get-stuff-done attitude
- Teams that focus on creating wins - for the org, the team and yourself - all fuelled by mentorship and empowerment
Our Culture
Some values we’ve lived by over these last 14 years:
We think like inventors.
>Invent the answer you wish existed. If it already exists, ask how it could exist better.<
We build for the love of it. And we build the best.
We don’t just copy and paste. We start from first principles—frame the problem, question the default, ship, improve, repeat—until it’s world-class.
Every version and experiment is a chance to push past our comfort zone and hone our craft. It isn’t easy—it takes patience and persistence—but it ends in work we’re proud of.
Ownership builds a rocket ship.
>It’s not the hours you put in your work that count; it’s the work you put in the hours.<
We’re here to build the business. When we see a problem, we own it end‑to‑end. We pull in the right people, ask for help early, track just enough to finish, and close the loop. We focus on what moves the needle, cut low‑impact work, and push hard when it counts—then recover.
That focus builds subject mastery. It helps get in the flow. It fuels passion and can spark healthy friction—and that’s all part of the game. We make a fuss when it matters, and once a call is made, we commit to it fully—whether we all agree or disagree.
Step up to stand tall.
>Greatness is a moving target.<
Chase excellence in your craft and take on bigger problems. Grow into a full-stack problem-solver and leader—whatever your domain. Improve with intent, work with people who push you, and never get too comfortable. That’s how we level up.
