Founding Engineer (Platform)

Location: Remote first (global, UK timezone)

Compensation: Up to £120,000 + significant equity

Type: Full-time

What is DeepFlow?

DeepFlow is the hyperscaling platform. We launch and scale AI-native businesses.

An operator with 10 years of domain expertise pairs with DeepFlow’s platform and engineering support to build a business that would previously have needed a team of 50. You’re building that platform.

Where we are now

• Platform live with paying customers across law, finance, recruitment, and media
• Launching our founding cohort through DeepFlow Foundry: deploying agents into real revenue-generating businesses
• Preparing for a significant raise to scale from 2–3 companies to 10+ by September, with a roadmap to 100 in 2027
• Research team published at AAAI 2026 (invited oral) and DAI 2025, with work adopted by top global universities and companies

The Role

You own the platform. The orchestration engine, the infrastructure, the client-facing dashboards, the integrations, the APIs - everything that isn’t the AI agents themselves. Your architecture decisions directly determine whether the businesses on our platform succeed at scale.

This is a full-stack, high-ownership founding role. You work directly with the CTO/CPO and CSO to shape product direction. Significant equity reflects the scope and impact of the position.

What You’ll Build

• Orchestration Engine: Event-driven task graph execution - breaking complex business workflows into composable steps, delegating to the right agent or human at the right time, with robust failure handling and retries.
• Core Platform: Auth, API endpoints, integrations (Slack, GSuite, CRMs, accounting tools), and dashboards. Everything that Foundry companies and their clients interact with daily.
• Infrastructure: Docker, EKS on AWS, CI/CD, monitoring, and cost management. You own the full stack from development through to production.
• Frontend: Client-facing dashboards, internal tools, and admin interfaces. This is a genuine full-stack role - you own the frontend, not just unblock yourself on it.
• Product Direction: You work closely with the founding team to translate cohort feedback and client needs into engineering decisions. What to build matters as much as how you build it.

What We’re Looking For

• Strong software engineering - you write clean, production-quality code and you ship fast. You’ve built and deployed real systems, not just prototypes.
• Genuinely full-stack. Backend, infrastructure, and frontend (React/TypeScript). You don’t wait for someone else to build the other half.
• Experience with event-driven or workflow orchestration systems. You understand what breaks when you move beyond simple request-response.
• Comfortable with AWS (EKS, IAM, networking) and modern CI/CD practices.
• Fluent with modern AI tooling - you use Cursor, Claude Code, or similar daily and it makes you faster. AI tooling is not optional here.
• Comfortable with ambiguity and startup pace. Priorities shift weekly based on cohort feedback.
• Right to work in the UK permanently.

We care less about

• Your degree (or lack of one)
• How many years you’ve been working - we care about what you’ve shipped
• Whether you’ve published papers

Tech Stack

• Backend: Python
• Frontend: TypeScript, React, Vite
• Infrastructure: AWS (EKS), Docker, Inngest (event-driven orchestration)
• Tools: Cursor, Claude Code, GitHub

Why Join

• Ownership. Significant equity as a founding engineer. The platform you build is the platform every Foundry company runs on.
• Real traction. Paying customers, founding cohort live, and a significant raise in preparation. What you build in the next 6–12 months directly determines whether we hit 10 companies by September.
• Exceptional team. Co-founder who sold his AI company to WPP for $100M. Product leader who scaled a Meta platform to 400K+ users. Research team published at top AI venues with work adopted by leading universities and Fortune 500 R&D teams. Advisors include a leading NLP researcher and a Google DeepMind team lead.
• Flexibility. Fully remote, UK timezone. Regular offsites. We care about what you ship, not when you’re online.

We’re hiring immediately. The process is fast: we make offers within one week.
