Back End Developer

You're a backend engineer who joined a B2B software team full of hope for what's next.

A few years in, one of three things has probably happened.

  1. The company scaled and the ownership narrowed. You're technically doing the same job but the feeling of building something that matters has quietly left.
  2. The company hasn't found PMF. You're working hard but the commercial outcomes aren't there, and forcing yourself in on a Monday is rough.
  3. You've had a blast, but you're jealous of your friends building AI-native products.

This role is the structural answer to all three.

I'm hiring two backend engineers for a London AI startup backed by LocalGlobe - the VCs behind Mistral, Figma, Monzo and Wise.

They've built the AI OS behind modern account-based marketing.

What used to take a marketer six hours, the platform does in minutes across thousands of accounts simultaneously - coordinating LinkedIn Ads, Microsites, Event Invites, and a Sales Plugin while processing millions of engagement events daily.

In under three years they've signed up 100+ enterprise customers including Stripe, Ramp, Canva, Datadog and NinjaOne. Their Head of Growth recently posted they're generating $33K of pipeline for every $1K of ad spend.

So why do those engineers like working there - and why will you?

There's no product managers here - the CTO sets overall direction, then hands off to the engineers, where you'll own everything from there.

Day to day will see you designing architecture via RFC before a line of code is written, owning Kafka event pipelines, BigQuery analytics infrastructure, REST API design for internal and public consumers, and contributing to feature planning decisions that most engineers never get near.

But unlike most product companies, you're not insulated from the people using what you build.

Occasionally you'll be on a call with an enterprise customer - understanding what they need, spotting what's broken. Then you go away and fix it yourself. The feedback loop most engineers never get to close is available here if you want it.

The engineers who thrive here aren't the ones who want to be left alone to code. They're the ones who find the whole problem interesting - the technical challenge and the commercial outcome it's connected to.

The team

CEO: ex-Salesforce Director of Enterprise Sales (AI division), then GTM lead at incident.io - built the product to solve a problem he lived firsthand.

CTO: ex-American Express engineering lead, ex-AI startup co-founder. Still codes.

Engineering team: Thought Machine, PlayStation, DoorDash, Foundry, Medtronic, Kraken.

What they're looking for

Strong backend fundamentals - understands systems at the level of why things fail, not just how to connect them.

Confident in Go, or fast picking it up from a strongly typed background. B2B/startup experience preferred.

Comfortable with ambiguity, context switching, and talking directly to customers. Thinks like a product owner, not a ticket executor.

Stack: Golang, Kafka, Postgres, Redis, BigQuery, AWS, React/Typescript (FE expertise not required)

Package: £80K-£120K + meaningful equity (mid and senior roles open)

25 days holiday. Apple hardware. Enhanced parental leave. Private gym in Shoreditch. Visa sponsorship available. Hybrid or remote working for UK based engineers available.
