About the role
Salary range: $80k – $165k USD*
We are looking for smart engineers who love to code, seek challenging problems and appreciate recognition for excellent work. As part of the Core UX team, you will focus on refining existing product functionality to deliver an exceptional user experience. Your work will center on ensuring consistency across the product, maintaining a cohesive look and feel, and implementing performance improvements that directly impact end users. You’ll be paying close attention to the layout, interactions, responsiveness, and visual polish, that collectively give the product a premium, well-crafted feel. This role is ideal for someone who enjoys iterative improvement, cares deeply about quality, and wants to shape the everyday experience of our users.
You'll collaborate with a global team of full-stack, data, ML, and DevOps engineers to build scalable backend solutions as we continue to grow. We're a small team where individual contributions have an outsized impact on both our technology and our business.
What you would do
- Have 5+ years of software engineering experience, ideally with a track record of improving and polishing functionalities to bring premium user experience.
- Embody hustle and grit, you're excellent at your craft and relentless in pursuing it.
- Take full ownership of your work and drive projects to completion with minimal oversight.
- Communicate proactively, surfacing blockers, asking the right questions, keeping stakeholders in the loop.
- Thrive on experimentation: you're comfortable testing ideas, measuring results, and iterating quickly on problems no one has solved before.
- Have strong fundamentals in system design, debugging, and problem-solving.
- You have experience in a modern FE framework, preferably React.
- Know Javascript, Typescript, or Python, though we're open to strong candidates from other OO backgrounds.
- Have experience with serverless technologies (Lambda, EC2), asynchronous workflows, and cloud environments.
- Are comfortable with relational databases, ideally PostgreSQL.
- Bonus: experience with LLMs/generative AI, distributed systems.
