Senior Software Engineer

Overview

I’m partnering with a high-growth, VC-backed Series B B2B SaaS company to hire standout Product Engineers!

Our client is reinventing how organisations manage and approve spend, from software requests to supplier onboarding, approvals, renewals, and supplier risk. The current purchasing process is slow, email-heavy, and painful for everyone involved. They are building the platform that fixes it.

They’ve already deployed the product with enterprise customers, are backed by tier-1 investors, and are now entering their next major scaling phase.

• Stage:
  Series B B2B SaaS scale-up
• Funding:
  Backed by top-tier VCs and high-profile operators
• Growth:
  Strong commercial traction with an ambitious plan to scale to 200+ enterprise customers over the next few years
• Leadership:
  Proven founders with experience building and scaling category-leading B2B businesses

They are looking to hire someone who wants more than just a ticket queue. This is a role for an engineer who wants to own problems end-to-end, shape the platform, influence technical strategy, and build product that customers genuinely love.

You’ll join a team with high talent density, strong product thinking, and a culture built around autonomy, pace, and accountability.

This is a modern, cloud-native platform built for speed and scale:

• Type Script
• React (Material UI)
• Node.js
• AWS Serverless (Lambda, Dynamo
  
  DB, Event Bridge)
• Postgres, Hasura
• Observability tooling (Sentry-style monitoring + session replay)

• Lead the design and delivery of high-impact full-stack features from concept to production
• Make architectural decisions to ensure the platform remains fast, reliable, observable and scalable
• Work across the stack - from React UX and styling through to AWS serverless backends and infrastructure
• Own projects end-to-end: product thinking, delivery, deployment, monitoring, and measuring real user impact
• Collaborate closely with Product, Design, and Leadership to define roadmap priorities and technical direction
• Deploy continuously - multiple times per day — through robust CI/CD pipelines
• Mentor other engineers and help build a high-performance, high-trust team

We are looking for, product-minded full-stack engineers who thrive in high-growth environments and want genuine ownership over what they build.

You’ll be a strong fit if you have:

• 8–12+ years of software engineering experience (flexible for exceptional candidates)
• Proven full-stack capability with Type Script, React, and Node.js
• Experience building on AWS, ideally within serverless architectures
• A track record of delivering excellent product experiences at speed, without sacrificing quality
• Strong judgement around system design, scalability, reliability, and observability
• A natural ownership mindset - you don’t wait for instructions, you drive outcomes
• The ability to mentor others and raise the bar across the team
• Helped scale an early-stage product through rapid growth
• Built side projects / contributed to open source because you genuinely enjoy engineering
• Demonstrated excellence outside work (academics, sport, etc.) - the “high performer” mindset

They place a strong value on in-person collaboration at this stage of growth, so this role follows a hybrid model of 3 days onsite in Victoria area.

This is a high-ownership environment where engineers are trusted to make decisions, move fast, and take responsibility for outcomes - with strong support from an experienced team.

• For the right candidates they are offering base salaries between £120,000–£160,000 + Meaningful Equity
• Hybrid working model (3 days in London: Tues–Thurs)
• Work closely with senior leadership as the engineering team scales

And plenty more I’d love to run through with you!
