Our Applied Science group builds the intelligence behind the marketplace. We turn large volumes of unstructured data into structured understanding, and use it to connect the right people with the right work. We are a small team with an unusually large surface. We own the full path from raw data to production AI systems, and we are actively expanding what that platform can do. In this role, you will design, build and operate AI systems that run continuously in production: large volumes of unstructured data in, models and pipelines in the middle, structured signal that teams across us build on back out. The scope runs from data pipelines and retrieval infrastructure through to model quality, evaluation and cost. This is a hands on senior role, and you will help define how these systems get built here rather than inherit someone else's answer.
What am I going to do?
* Build and evolve our production LLM pipelines, turning unstructured text into structured data that the product consumes.
* Design and operate large scale batch and near real time data processing, including correctness, freshness and cost.
* Build the retrieval and serving layers that make our data usable in real time.
* Decide what runs on which LLM model, and prove the choice with numbers rather than intuition.
* Keep cost and latency predictable as volume grows: throughput, failure handling and monitoring.
* Build agentic workflows that makes the whole team faster, and help set the standards others work to.
Equal opportunities:
We prioritize diversity. We celebrate difference and embed it into every aspect of our workplace and product, as well as our community. We are proud and committed to providing equal opportunity employment to all individuals regardless of race, color, religion, sex, sexual orientation, citizenship, national origin, disability, Veteran status, or any other characteristic protected by law. In addition, we will provide accommodation to individuals with disabilities or a special need.

Collaborate with engineers and product managers to deliver robust solutions in short development iterations.
Develop maintainable and clean code with heavy reliance on developer testing
Make thoughtful trade-offs based on business priorities, user needs, and a sustainable technical foundation.

We are establishing a new backend group that will take full ownership of a core application area.
We are looking for a Senior Backend Developer who will lead the backend effort end-to-end - from initial architecture and technology choices, through implementation and scaling, and into long-term ownership and evolution.
This is a hands-on technical leadership role. You will design, build, and own production systems, work closely with multiple teams, influence product direction, and set the technical bar for the group.
We embrace an agile mindset - you should be comfortable with context switching, handling multiple priorities, and adapting quickly to changing requirements.

Mentor and technically guide other backend engineers as the group grows.

We're looking for a designer who sees the system before the screen one component change and you already know what breaks three flows away. Someone who moves fast without getting sloppy: you can produce five directions before lunch and still catch the 2px misalignment in the one you ship. You question the brief if the ask doesn't solve the real problem, you say so, with a better idea in hand. You obsess over the details nobody asked for, from the easing curve to the microcopy to the loading state that makes waiting feel intentional. You think in principles, not preferences, and can defend a decision with reasoning rather than taste. And you leave ego at the door: you're as excited giving feedback as receiving it, and the best idea in the room wins regardless of whose it was.
On Your Day-to-Day:
Own full platform areas end-to-end problem framing through shipped, polished product
Push the design system forward, not just apply it
Partner with product and engineering as an equal
Collaborate closely with the rest of the design team critique each other's work, borrow each other's ideas, and make each other better
Report to a manager who's also a designer at heart someone who'll dig into the details with you, not just review the deck
Use research and data to sharpen instinct, not replace it
Raise the bar for craft across the whole team your standards become the standard
