Senior Fullstack Engineer

Role Description

We are looking for a Senior Fullstack Engineer who thinks like a Product Owner. You will work closely with our Product and Business teams to understand our customers’ pain points, design solutions, and actually write and ship code to directly solve problems. Your key responsibilities will be:

• Software Engineering: Deliver a best-in-class product. Do this in a way that makes everyone on the engineering team more efficient by directly building the systems, tools, and frameworks needed to allow high-velocity iteration.
• Product Ownership: Work with the product team, business team, and directly with our customers to come up with new features and improvements that impact our product development roadmap.
• Technical Leadership: Lead by example to help develop our engineering team’s practices, particularly when it comes to testing and scaling a product whose core functionality involves large-scale, complex, sensitive data processing.

Qualifications

• Hands-on expertise: You may have managed or led at points in your career, but you still code regularly and are interested in continuing to do so. You’ve been in charge of larger projects or initiatives and know how to work well with others.
• Strong written communication skills: You are used to writing about, speaking about, and generally communicating complex technical subject matter both to other engineers and to non-engineers.
• Early-stage mentality: You understand that success at a startup involves grit and determination. You have good taste when it comes to trading off speed vs. perfection. You know when to cut corners but aren’t afraid to advocate for rigor when you believe it’s necessary.
• True fullstack experience: While you may be stronger on the backend or on the frontend, you are strong in either domain and have a track record of delivering projects involving both.
• AI forward: You are actively experimenting with or using AI as part of your software engineering practice. You don’t send vibe-coded slop to your teammates to review, but you use AI appropriately to achieve great results.
• High ownership: You care a lot about your work and when you ship a product, you make sure it continues to solve problems for the customer. You care a lot about the customer, the overall business, and are constantly trying to help achieve success — with or without code.

Requirements

• Adtech experience: You’ve worked in adtech, particularly mobile adtech, and have a good understanding of the broader ecosystem and market.
• AI product experience: You’ve built products or side projects that involve AI. You have a decent idea about what’s possible with current models and APIs, as well as a sense for what might be possible in the near future. You’ve spent time actually integrating with large foundation model APIs.
• Stack experience: Our backend is written in Golang, we put application state in Postgres, we store a lot of event data in Clickhouse, we use Datadog for observability. Our frontend is Typescript, React, Vite, Tailwind, Biome, ESlint. We deploy on Vercel. Familiarity with any or all of these, particularly Golang and React, is a strong positive.

Benefits

• The annual US base salary range for this role, and other engineering roles, is $150,000 – $300,000. This salary range is broad in order to accommodate a wide range of candidates; the interview process will narrow it down based on a number of factors, including your experience, qualifications, and location.
• We offer equity compensation and top-tier medical, dental, and vision benefits.
• We also have a generous hardware budget for a computer, monitor, and other core equipment necessary to work effectively on a remote team.
• We care about the quality of your work more than the specific hours you spend getting it done, and try to minimize the number of synchronous meetings in favor of greater flexibility. There is no in-office requirement.
