Security Engineer

Open Application Overview

We’re always excited to connect with exceptional people here at Unit 410 — because we believe in growing a strong team by building relationships before we need to hire.

If you're excited about what we're building, we'd love to get to know you — whether the timing is right today, or months from now.

This is a special team, made up of folks who have worked on some of the world’s most high-impact technologies, at places like NASA, Google, Coinbase, and Twitter.

We're frequently the team powering the “next big thing” in crypto. We support large, early holders on networks and work directly with founders and CTOs. Peers often look to us as industry leaders.

As a member of the Unit 410 team, you will enjoy autonomy and be encouraged to lean into intellectual curiosity. Your work here can make an impact not just on the company, but often across the broader crypto industry.

Tell us what drives you — the hard problems you can’t stop thinking about, the impact you’re hungry to make. If your ambition aligns, we’ll find a way to build together.

Role Overview

As a Security Engineer at Unit 410, you’ll be on the front lines securing the edge of crypto infrastructure and systems. You’ll work across our Engineering teams to lead, review, and implement security improvements across our entire stack — designing cold storage, building airgapped systems across cloud and hardware, and developing high-signal detections for both on- and off-chain threats. It’s high-impact work that touches every layer of the stack — perfect for someone who loves diving deep, thinking like an attacker, and shipping defenses that actually hold up.

What You’ll Be Doing

• Fortify Wallets — Design secure-by-default wallet architectures that interact with emerging crypto protocols. You'll partner closely with other engineers on the team to identify risks, shape the right design for the business, and clearly surface any tradeoffs.

• Lock Down Systems — Work across teams to build and harden systems from the ground up — online, offline, and everywhere in between. Think code signing, secure deployment, access control, and more.

• Detect & Respond — Build high-signal detection across both cloud and on-chain environments. You’ll automate alerts, simulate threats, and drive response plans to stay ahead of real-world compromise.

• Audit What Matters — Assess security from code to cloud. You’ll review internal systems and open source dependencies, fix what you can, and help teams prioritize what’s left — without losing sight of the big picture.

Who You Are

• Hands-on experience working in production environments at any scale, with ideally 5 to 7 years of experience.

• Curiosity to dive deep into emerging crypto protocols (specs, code, and edge cases).

• Strong judgment on what matters most, and a bias for shipping secure systems.

Tech Stack & Tooling

• Languages: Go, Rust, Typescript

• Protocols: Substrate, Tendermint, and many more…

• Security: System hardening (hardware, libs, tooling), physical, and environmental monitoring
