At the core of our company’s identity is a strong foundation in engineering.

About the Role
We’re looking for an engineer who’s ready to level up—not just in skill, but in impact. This role is built for someone who enjoys solving complex, not-fully-defined problems and wants to play an active part in shaping the product.
You’ll be working on a system that’s evolving in real time, where your ideas and contributions directly influence what gets built and how it performs.
You thrive in collaborative environments where ownership is shared, ideas are challenged, and progress happens as a team. You’re naturally curious, comfortable with ambiguity, and motivated by building something meaningful—not just maintaining it.
If you enjoy turning complexity into clarity and want to grow alongside a team tackling hard problems together, you’ll feel right at home here.
