Founding / Early Engineer

Series A Cyber Security Startup | Well-Funded | Elite Team

We’re working with a Series A cyber security startup tackling genuinely hard problems in a critical, fast-growing market. The company has moved beyond idea-stage, has real traction, real customers, and serious momentum — now they’re scaling the engineering team with exceptional builders.

This is a Founding / Early Engineer role where you’ll help take a strong core product from early traction → real scale.

Why this stands out

Elite engineering DNA – team includes engineers from Meta, Tessian, and top-tier security companies
Proven founders – previous successful exit, now building with clarity and pace
Strong Series A backing – significant VC funding, long runway, clear growth plan
Real impact – you’ll influence architecture, hiring, and engineering culture as the team scales
Serious problems – modern cyber security challenges involving scale, reliability, and adversarial systems

The role

Build and scale core backend and platform systems
Contribute to architectural decisions as the product and customer base grow
Work closely with product and leadership on technical strategy
Help establish best practices around quality, security, and scalability
Mentor and raise the bar as the team expands

What they’re looking for

5+ years commercial software engineering experience
Strong fundamentals across system design and software architecture
Experience in high-bar teams or fast-growing startups
Language-agnostic mindset (Python, Go, Rust, Java, C++, TypeScript all welcome)
Comfortable moving from hands-on delivery to higher-level technical ownership

The upside

Competitive salary + meaningful equity
Stability of a Series A business with the influence of an early hire
Learn from exceptional engineers and founders who’ve done this before
Clear progression into Staff / Principal / Tech Lead paths as the company scales

This is ideal for engineers who want ownership without chaos — still early, still impactful, but with real backing and direction.
