Co–Star Astrology | Haskell Developer | Full-time | NYC or Remote (US) | $152k-$205k + equity + benefits

Every 3 seconds, someone downloads Co–Star. We’ve reached 30% of 18–25 year olds in the US without spending a dime on marketing.

We use astrology to get at something deeper: how people reflect/connect in a chaotic, atomized world. The horoscopes are generated by a custom stack that mixes functional programming and AI with real human poets and astrologers.

You’d be writing Haskell, building ML infra, and scaling data pipelines.

We’re a small team that cares about systems design, poetry, psychoanalysis, and doing things in a principled way. We also care about profitability and efficiency, because they keep us alive.

If you’re into weird problems at the intersection of tech and culture, come help us build some cool shit.

Questions: Email is hidden - I'm Hal, I manage the backend.

AbbVie | AI/Software Engineer | Remote, UK/EU | Full-time

Are you a great coder (Python/Typescript, but great skills are transferrable), who enjoys close collaboration with end-users in solving their hard problems?

Do you have a solid foundation in the AI/LLM-world - or are you a great at the above and willing to learn?

Are you well versed in data engineering concepts, and excited to work with the latest GenAI models and bring these solutions into production? Then I'd love to hear from you!

We are a small team who care deeply about our work as well as each other. We iterate fast, and err on the side of showing a quick prototype of an idea, rather than spending hours in meetings talking about it.

Our vision for this project is extremely ambitious, and you will be a crucial part of making this a reality. We've been expanding the team, and are currently looking to fill a few extra roles in the UK/EU.

Title: Full-Stack Engineer | Contract | Remote (US-based)

Company: Audio-First Test Prep Platform

Duration: ~10–12 weeks for MVP

Compensation: Paid contract – competitive rate (no equity)

Experience Level: Mid to Senior preferred (3 years +)

Funding: Final stages of mobilizing resources to begin the MVP build. The project timeline reflects this progression.

We’re building an adaptive, audio-driven test prep platform designed for nurses, pre-med students, law students, and other high-intensity learners balancing work, family, and study. Think voice-based Duolingo meets real-time spaced repetition.

We’ve already built the front-end and now need a self-directed, back-end/full-stack engineer to help us finish the MVP by late summer, early fall.

Ideal Stack (flexible):

* Node.js / Python / Firebase / Postgres / Supabase

* Open to suggestions if justified and lightweight

You might be a fit if:

* You’ve built and launched real tools or platforms before (not just internal dashboards)

* You like fast execution but also appreciate mission-driven projects

* You value clarity, minimal meetings, and aligned momentum

* You have the capacity for solo execution but are open to scaling

* We’re not offering equity or co-founder status. This is paid contract work with possibility for long-term relationship once MVP proves value.

More info + how to apply: (https://hail-peridot-e09.notion.site/hiring-full-stack-softw...)

*This is a time-sensitive build that requires steady focus. Please only apply if you're able to be fully present during this phase.*
