Role
Who you are
- Are you a full-stack developer who loves building beautiful user experiences and harnessing the power of cutting-edge AI?
- Strong engineering background: You have around 5+ years of experience building software, with significant exposure to front-end development for rich, interactive web applications
- React & TypeScript guru: Deep knowledge of JavaScript/TypeScript and hands-on experience with React (or similar frameworks). You can build dynamic single-page applications and have a good sense for component design, state management, and performance in the browser
- Backend capable: Comfortable writing back-end code in Python and/or Go (or similar languages). You understand how to build APIs, work with databases, and wouldn’t shy away from digging into server-side logic when the situation calls for it
- Database and data savvy: Experience working with databases and data pipelines. For example, you’ve used PostgreSQL or other SQL databases, and maybe even played with analytics or search technologies like ClickHouse or Elasticsearch. You know how to design data models or queries that scale efficiently
- Design and UX mindset: You care about the user. Maybe you’re not a designer, but you have a knack for building UI features that are intuitive and delightful. You think about things from the user’s perspective and want to make complex things feel easy
- Problem solver: Proven ability to break down complex problems and come up with clean, workable solutions. You enjoy the puzzle of turning a hard technical or UX challenge into an elegantly resolved feature
- Collaborative communicator: You work well in a team and communicate clearly. You’ve collaborated with product managers, designers, or data scientists before, and you value everyone’s input. You’re comfortable discussing trade-offs and explaining your ideas to both technical and non-technical stakeholders
- Passionate about AI: You’re excited about the AI/ML space and the idea of working on a product that involves AI. You don’t need to be an AI expert, but you are eager to learn more about it and work alongside AI/ML experts to bring intelligent features to users
What the job involves
- We’re looking for a Fullstack Engineer to join us at Cresta and help take our AI Agent Builder platform to the next level. In this role, you’ll focus primarily on the front-end (while diving into the back-end as needed) to create an intuitive builder that lets users craft their own AI agents with ease and confidence
- You’ll work closely with Product, Design, AI/ML, and Data teams to bring this vision to life
- We’re looking for engineers with a high-agency mindset—people who take initiative, move projects forward without waiting for perfect instructions, and creatively navigate challenges
- You’ll have the autonomy to drive impactful features end-to-end, shape user experiences that make AI accessible, and solve complex technical and UX problems with ownership and persistence
- Imagine working on a platform that gives people superpowers to build AI
- That’s what the AI Agent Builder is all about – an innovative self-serve tool that empowers anyone to design and deploy AI-driven agents through a friendly interface
- It’s cutting-edge AI meets intuitive design
- By joining our team, you’ll be at the forefront of an exciting movement to democratize AI technology, making it accessible and impactful for businesses and users everywhere
- Build amazing user interfaces: Use React and TypeScript to craft responsive, engaging front-end features. Make complex AI workflows feel simple and elegant, so that users of all technical levels can successfully build AI agents
- Work across the stack: When necessary, jump into our Python/Go back-end to create or improve APIs and services that power the Agent Builder. You’ll ensure that the front-end and back-end work together seamlessly to deliver a smooth user experience
- Collaborate & co-create: Partner with product managers to shape feature ideas and requirements. Brainstorm with designers to nail a user experience that is both powerful and easy to use. Work side-by-side with AI/ML engineers to integrate state-of-the-art AI capabilities (like our latest models and algorithms) directly into the product. Team up with data engineers to track how users interact with the platform, using insights from Postgres, ClickHouse, Elasticsearch, etc., to guide improvements
- Emphasize scalability: Contribute to the design of a system that can grow with our user base. Optimize performance whether it’s front-end rendering or back-end data queries, so the platform stays fast and reliable as more users build more agents
- Lead by example in code: Write clean, well-documented, and tested code. Perform code reviews, share best practices, and help elevate the team’s engineering standards. You’ll have the autonomy to own features from concept to deployment, ensuring they meet our quality bar at every step
- Solve tricky problems elegantly: Every day brings new challenges – maybe it’s how to simplify a complex configuration process or how to visualize AI behaviors in the UI. You’ll tackle these challenges with creativity, keeping the solutions user-focused. We love it when hard problems end up with simple, intuitive outcomes for our users!
