2 Days Old

Lead Full Stack Engineer | Hybrid - 2 days onsite, London | £100,000 - £120,000 DOE
We're partnering with a high-growth B2B PropTech SaaS business that's transforming how property professionals access and leverage land data across the UK.
In just a few years, the company has built one of the most advanced property data platforms in the market, integrating thousands of data sources and processing terabytes of information with sub-24-hour latency. With strong product-market fit, continued revenue growth, and ambitious scaling plans, they're now hiring a Lead Full Stack Engineer to help shape the next phase of the platform.
This is a hands-on leadership role within an engineering-led, collaborative environment, ideal for someone who enjoys balancing architectural ownership with meaningful day-to-day coding.
The Role
As Lead Full Stack Engineer, you'll combine deep technical expertise with strong leadership and architectural oversight. You'll drive technical excellence across the organisation, mentor engineers, and influence the long-term direction of the platform.
This is not a purely managerial role, you'll contribute to the codebase daily while also shaping standards, systems, and engineering culture.

Provide architectural oversight across frontend, backend, and data infrastructure
Set engineering standards and champion best practices in scalability, reliability, and maintainability
Lead complex system design discussions, balancing speed, scope, and long-term scale

Hands-On Engineering
Develop high-quality front-end features using React (Vite) + Tailwind
Design and ship scalable, type-safe APIs using Node.js, Express, and tRPC
Optimise and maintain PostgreSQL databases and query performance
Collaborate with the data team to evolve Elasticsearch-driven architecture
Own delivery of complex features from discovery through deployment and monitoring
Team Leadership & Cross-Functional Impact
Mentor senior and mid-level engineers through pairing, reviews, and coaching
Foster a high-performance engineering culture built on ownership and continuous improvement
Work closely with product, design, and data stakeholders to ensure technical input shapes roadmap decisions
Translate complex technical challenges into clear, actionable insights for non-technical teams
What We're Looking For
7+ years' experience in software engineering
2-3+ years operating in a Lead, Staff, or Senior+ capacity
Proven experience building and scaling SaaS platforms
Experience leading architectural decisions and system design initiatives
Strong full-stack capability in modern JavaScript/TypeScript environments
Tech Stack
Frontend: React (Vite), Tailwind
Backend: Node.js, Express, tRPC
Databases: PostgreSQL, Elasticsearch
Strong adjacent experience is also welcomed.
Nice to Have
Experience in PropTech or data-heavy platforms
Familiarity with UK property, planning, or geospatial datasets
Experience helping scale engineering teams in high-growth environments
Why Apply?
Hybrid working (2 days onsite in Central London)
Competitive salary + EMI scheme
25 days holiday + bank holidays + birthday off + Christmas shutdown
Health cash plan (including dental)
£500 annual personal development budget
MacBook + home office contribution
Collaborative, ambitious team culture with regular socials and company trips
Interview Process
Initial video-based screening
Technical task (React + Tailwind + tRPC + PostgreSQL)

Final interview with senior leadership
If you're an experienced engineer who thrives on combining technical depth with leadership impact, and you want to help scale a genuinely high-impact data platform, we'd love to share more.
