Founding Backend Engineer

Agile Venture-Backed Startup

Up to £100,000 + benefits

The Company

• My client builds the real-time operational brain for critical infrastructure, transportation, and aviation turnaround logistics.

• Replaces static spreadsheets, radio chatter, and paper manifests with stateful, dynamic execution engines.

• Operates a domain-independent platform managing reactive event loops and forward scheduling at scale.

• Backed by top venture capital with dual hubs in London and San Francisco.

Why Join?

• Complete ownership of the core backend platform (Maestro) serving critical real-time operations globally.

• Solve hard distributed system challenges: exactly-once effects, concurrent write resolution, and multi-tenancy.

• Founding-level impact: shape backend engineering standards, observability, staging validation, and technical hiring.

• Direct field exposure: spend time on airport ramps observing how live operations interact with your code.

The Role

A technical, hands-on role where you will:

• Build stateful microservices, event-driven ingestion pipelines, and state machines in Python and PostgreSQL.

• Design multi-tenant architecture enabling seamless onboarding of new sites and customers through configuration.

• Ensure sub-second bounded read latency, fault-tolerant execution, and zero-downtime production deployments.

• Interface third-party operational feeds, legacy channels, and communication streams into a unified data schema.

• Define robust TypeScript API contracts consumed by the frontend and establish testing/on-call standards on AWS.

• Work directly on-site with live operational staff to fold real-world feedback into platform capabilities.

The Essential Requirements

• 3+ years of production backend software engineering experience using Python.

• Strong relational database modeling expertise in PostgreSQL, covering concurrency, locks, and idempotency.

• Hands-on experience with event-driven architectures, state machines, and AWS cloud environments.

• London-based location with full eligibility to work in the United Kingdom.

What Will Make You Stand Out

• Experience architecting multi-tenant B2B SaaS platforms at scale.

• Background building integrations against legacy third-party operational or logistics data feeds.

• Founding engineer mindset with a passion for direct customer contact and field-level operational discovery.
