Help us raise the average IQ of humanity.

As a Principal Software Engineer, you will lead the design and development of the core technical systems behind Astral's AI-driven learning platform, spanning backend architecture, infrastructure, data systems, model pipelines, evals, and the serving layers that generate and deliver personalized curriculum at scale. You should be highly comfortable working across distributed systems, AI cost optimization, databases, Kubernetes, data-intensive applications, observability, and production infrastructure, while still being able to dive deep into backend product logic when needed. This role is for an engineer who can simplify complexity, make excellent architectural decisions under ambiguity, and raise the technical ceiling of the entire company. We would only like to work with engineers who truly believe they can build just about anything, and who care deeply about reliability, scalability, latency, cost, and craft.

As a Senior Backend Engineer, you will lead the development of the backend systems that drive pipelines and logic for AI-driven teaching workflows, and the creation of freshly minted, AI-generated multimodal learning content. You will be implementing backend business logic with a key attention to detail: build something you would love to use. You should be highly comfortable with systems design, architecture, API logic, data structures, and databases, and with shipping production-ready code. We would only like to work with other engineers who also truly believe they can build just about anything.

As a Senior Frontend Engineer, you will craft intuitive, responsive, and pixel-perfect user experiences across multiple platforms, translating design systems, UX wireframes, prototypes, and product requirements into stellar frontend experiences. You should consider yourself a true craftsperson with React: you understand its inner workings, you're deeply attentive to detail, and you want to write elegant, minimal code. You should have great taste when it comes to frontend interactions, cross-platform usability, performant design patterns, state management, and componentization. Depth with CSS, HTML, and JS is a must if you'd like complete control of the DOM and the browser on all platforms.

As a GTM Engineer, you will own the systems that bring families to Astral: paid acquisition, our referral program, and the growth loops that connect them. You'll launch and scale campaigns across Meta, Google, and whichever channel comes next, and grow the referral program that turns parents who love Astral into our best marketers. This is an engineering role on the growth side. You'll ship landing pages and experiments yourself, wire up attribution and conversion tracking end to end, and read the funnel in SQL rather than waiting on someone else's dashboard. We want someone who treats growth as a system to be built, moves fast, and cares about reaching every family who needs a better way to learn.
