Senior Fullstack Engineer

About CloudX

About The Team

What you'll do

• 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.

Who you are

• 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.

• 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.
