Founding Engineer | Cybersecurity

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.
