CAREERS

Who is Eleos Health?

Today, more people than ever are speaking publicly about their mental health. Whether it’s ourselves, our friends and family, or even public figures, taking care of your behavioral health is no longer a taboo — it’s vital, and it’s only human.

Eleos is on a mission to help deliver the world’s most effective behavioral care through data, measurement, and personalization. Or simply put, we want to give clinicians the support they need to do the important work only they can do.

What is this opportunity?

We’re looking for a Full Stack Engineer to join our innovation team — a small, high-autonomy group focused on discovering and building Eleos’s next growth engines.

This is a startup-within-a-startup opportunity: you’ll help take early ideas from 0→1, validate them quickly in the market, and shape what could become the company’s next major product line.

We move fast and operate in ambiguity — but we do it with care. You’ll build lean, production-ready prototypes that can evolve into scalable solutions, balancing speed with technical soundness. Our goal is to move fast without breaking things that matter.

You’ll collaborate closely with Eleos’s R&D, Product, and Data teams, ensuring your experiments align with the company’s architecture, principles, and long-term direction.

Who are you?

You’re a builder at heart — someone who loves turning rough ideas into working products. You’re comfortable switching between backend, frontend, data, DevOps, or QA if that’s what it takes to move forward.

You thrive in uncertainty but know when to pause and build things the right way. You understand how to make pragmatic trade-offs between time to market and maintainability.

You enjoy working independently, but you also value alignment and collaboration with the broader engineering organization to ensure what you build can grow sustainably.

How will you contribute?

• Build and deliver end-to-end prototypes and MVPs across varied tech stacks — from web apps to AI-driven tools.
  
  
• Balance speed and craftsmanship: build for learning, but with an architecture that allows scaling if the experiment succeeds.
  
  
• Collaborate with Product, Data, and R&D peers to validate hypotheses, integrate with existing systems, and share learnings.
  
  
• Take ownership from ideation to delivery — including scoping, development, and feedback loops.
  
  
• Contribute to a culture of experimentation, pragmatism, and technical excellence.
  
  

What qualifications and skills will help you be successful?

• 8+ years of hands-on experience as a full-stack engineer.
  
  
• Proficiency in React (or similar modern frontend frameworks) and Node.js / FastAPI / equivalent on the backend.
  
  
• Solid understanding of data models, REST/GraphQL APIs, and cloud infrastructure.
  
  
• Strong system design instincts, you know how to build for flexibility and speed without leaving chaos behind.
  
  
• Comfort operating autonomously in a fast-changing environment and collaborating across teams.
  
  
• Proficiency with AI-coding tools and rapid prototyping.
  
  
• Bonus: experience with AI integrations and browser extensions.
