Senior Full Stack Engineer Join a High-Growth AI Start-Up
Remote
Competitive Salary + meaningful equity
Omnis Partners is working exclusively with a rapidly scaling AI start-up redefining how enterprises build and deploy AI products. Their platform enables organisations to go from concept to production in a matter of weeks and is already delivering tangible impact for global clients.
With early products live and gaining traction, the business is now entering a critical scaling phase as they build out a platform designed to operationalise AI at enterprise level.
Why this opportunity stands out:
• Proven product-market fit - already adopted by major enterprise customers
• Well-funded & capital efficient – Series A secured in days, already generating revenue
• Huge growth curve – upcoming platform launch expected to significantly accelerate adoption
• Elite, small team – highly technical, low-ego engineers building from first principles
• Clear exit potential – early signals of interest from large tech players and consultancies
• AI-native vision – building a development environment purpose-built for modern AI systems
What you'll be doing:
• Take ownership of full product features, from UI/UX through to backend systems and deployment.
• Drive architectural decisions, balancing speed with scalability and robustness.
• Build and optimise AI-driven workflows (streaming, async processing, state-heavy systems).
• Support and elevate the team through mentorship, collaboration, and thoughtful code reviews.
Tech environment:
• Frontend: TypeScript, React, Next.js.
• Backend: Python (FastAPI or similar), async programming, API design.
• Data: Postgres, schema design, performance tuning.
• Auth: OAuth/OIDC, JWT, RBAC/ABAC.
• AI exposure: LLM integrations, function/tool calling, streaming pipelines, vector DBs, agent-based systems.
This is a high-ownership, fast-moving environment with strong engineering autonomy. You'll have real influence on both the product and company direction at an early stage with flexibility to work remotely, a competitive package, and equity that reflects the scale of the opportunity.
