Founding Software Engineer

About Noïa Labs
Noïa Labs is an early-stage neurotechnology company building the next generation of human-AI interfaces.
We're tackling one of the most ambitious problems in human-AI interaction: decoding human intent directly from brain signals, in real time and without surgery, to control and collaborate with AI systems.
Our approach combines optimized neural sensors with large-scale AI models trained across many users, a technical challenge that sits at the intersection of neurotechnologies and frontier AI.
Founded by the team behind NextMind (acquired by Snap) and backed by tier-1 investors, Noïa Labs is starting its journey and hiring a team of outstanding engineers and scientists where each person will have a major impact on the product and technology.
Your Mission
You will be creating the software layer of a non-invasive neural interface, by building the applications, services, and real-time pipelines that connect our devices, neural data, and ML models.
This is a hands-on role for someone who moves quickly across the stack, ships end-to-end, and cares about quality.
You'll own the backend APIs, data interfaces, model integration, and internal tooling, working closely with ML engineers, neuroscientists, and product teams.
What you'll do:

• Design and build full-stack applications that connect neural signals, AI models, and user interactions in real time
• Create the interfaces and internal tools that power how our teams collect data, train models, and iterate on product
• Architect the backend layer services, APIs, device integrations, neural decoders, databases
• Build agentic infrastructure from the ground up: tool use, memory, retrieval, context, and state management for AI systems
• Improve system reliability, performance, observability, and user experience
• Work with ML and neuroscience teams to turn prototypes into product features

What we are looking for:

• 5+ years building and shipping software in a full-stack, backend-leaning role
• A track record of owning features end-to-end.
• Strong backend fundamentals: APIs, databases, cloud infrastructure
• Solid grasp of software architecture, with a care for reliability, performance, and security.
• High ownership, good product instincts, autonomy, leadership and decision making skills.

Benefits & Compensation:

• Equity package
• Full health coverage, employer-paid through Alan
• 100% reimbursement of public transport costs (Paris-based)
• Meal vouchers at €11 per working day, 60% company-funded
• New MacBook Pro
• RTT (extra days off)

Even if you don't check every box in our requirements, we encourage you to apply. We value diverse perspectives and backgrounds, and we're more interested in your potential and passion than a perfect match to our checklist.
