I’m partnering with a well-funded, early-stage cybersecurity intelligence company building a next-generation third-party and supply chain risk platform. They’ve closed seed funding, are preparing for Series A, and are scaling both their core engineering team. They’re now hiring a Senior Fullstack Engineer - someone who cares deeply about clean code, strong systems, and growing alongside a high-calibre team.
The Opportunity - You’ll work across the stack (backend-leaning), helping build and evolve a platform that ingests and processes large-scale intelligence data used by security, finance and resilience teams. You’ll:
- Build and maintain backend services (TypeScript / Node.js)
- Develop and extend APIs (Fastify)
- Contribute to high-volume data ingestion and processing workflows
- Ship frontend features in React / TypeScript when needed
- Write clean, well-tested, well-documented code
- Participate actively in code reviews and engineering standards
- Collaborate closely with Product and Engineering leadership
This is a hands-on builder role - not just feature delivery, but meaningful contribution to how the platform evolves.
What They’re Looking For
- 3+ years backend experience (strong Node.js / TypeScript)
- Comfortable working across the stack
- Experience in collaborative engineering teams where quality matters
- Someone who understands good system design - even if you haven’t led architecture yet
- Clear communicator, great team player, high ownership
Bonus if you’ve worked with:
- Python (data processing / automation)
- Data pipelines or high-volume ingestion
- Graph / relationship modelling
- Security, risk or intelligence platforms
- AWS or infrastructure-as-code exposure
Why This Role Is Interesting
- Early high-impact hire - funded, structured, and growing intentionally
- Strong technical leadership to learn from
- Real ownership without being thrown in the deep end
- Meaningful equity at Seed → Series A stage
- Cyber / supply chain risk - a space that’s only becoming more critical
This is ideal for someone who wants to level up technically while still having tangible impact on a product from its early stages. Reach out to me directly or apply to find out more!
