Job Summary

Software Engineer

Location: London (in-person with flexibility)

Type: Full-time

Stage: Pre-seed

Equity: Meaningful early equity

Listo is building the infrastructure layer for AI-native distribution.

We help companies turn their existing APIs products and services into AI-native applications that run inside platforms like ChatGPT and other agentic systems.

We automate the entire lifecycle of AI app integration: MCP server generation AI-native UI hosting deployment monitoring and optimisation for invocation and visibility.

Our ambition is bold:

AI platforms are the next major distribution channel much like the App Store was a decade ago and we want to empower any business to participate.

We are an early-stage company operating at the edge of a fast-moving ecosystem. This is not a maintenance role. Its about designing shipping and operating new infrastructure under real-world constraints with real customers and real stakes.

Were looking for a Software Engineer to join Listo and help build the core platform alongside the founders and CTO. Youll work on production systems integrations and automation pipelines contributing directly to features that ship to customers.

Tasks

What Youll Do

Build and evolve backend systems and third-party integrations
Contribute to automation pipelines and agentic workflows
Ship production features used by real customers
Collaborate closely with founders and the CTO on technical decisions
Take ownership of specific systems or components as the platform grows

Requirements

What Were Looking For

Youll be a great fit if you:

Have solid software engineering fundamentals
Have experience working with APIs backend systems or integrations
Are comfortable writing production-quality code
Take responsibility for the systems you build

Preferred Tech Stack

Experience with some of the following is a plus:

Backend: TypeScript Python
APIs & Integrations: REST OpenAPI GraphQL
Automation / Agentic Systems: LLM-based workflows task orchestration
Infrastructure: Docker CI/CD GCP or AWS (basic Kubernetes knowledge a plus)
Observability: Logging metrics basic monitoring

You Might Be an Excellent Fit If

You have previously built agentic systems MCP servers or AI-native applications.
You enjoy working on platform or infrastructure-adjacent problems
You want to grow into a role with more ownership and responsibility
You want to have a good time with a young and energetic team of founders
