Role
Who you are
- AI-native. Non-negotiable. You leverage AI to operate as a 10x engineer — demonstrable AI proficiency is a hard requirement, not a nice-to-have
- You see what needs to exist and you go build it — you spot the gap, scope it yourself, and start, instead of waiting for someone to hand you a task or a spec
- You lead by taking the hardest, least-defined part of the problem and making it work, and others follow because your judgment and output earn it — not because of a title
- You own the entire arc — design, build, ship, operate — and you treat what happens in production as your responsibility, making sure the system behaves exactly within the parameters it's supposed to, not just that it passed in staging
- When you hit the edge of what you know — a protocol you've never touched, a failure mode you've never seen — curiosity and sheer grit carry you across it faster than most people expect
- "Good enough" makes you uncomfortable; you hold a high bar for yourself and ship work you're genuinely proud to put your name on
- Proven, demonstrable proficiency using AI as a force multiplier — you already operate as a 10x engineer, orchestrating AI tools and agents to design, build, and ship far beyond what you could alone, while keeping the judgment to know what "correct" actually looks like
- 5–7+ years building and operating production services and front ends, with real experience owning something end to end and carrying the weight of it once it's in front of real users
- Hands-on experience with TLS / MITM inspection and the security-sensitive edge cases that come with sitting in the middle of live traffic
- A real track record of taming latency in streaming and distributed systems — you've chased down p99 tail latency and know that "fast on my machine" means nothing until it's fast in production, under load, with observability to back it up
- Strong command of a modern backend language (Go, Rust, or TypeScript/Node) and React/TypeScript on the front end, with a deep working grasp of HTTP, TLS, gRPC/REST, and async/streaming I/O
What the job involves
- We're assembling a small founding team to build something genuinely hard: high-throughput services that inspect live traffic, terminate and analyze TLS in the data path, and hold near-zero latency while doing it. This is real systems engineering — streaming, distributed, latency-obsessed — not another CRUD app behind a form
- You won't be starting cold. You inherit real infrastructure and real users, which means what you build reaches production in weeks, not years. The work is high-leverage from day one, and there's nowhere to hide — in the best way
- You take a capability from a rough idea all the way to production, and then you keep it alive and healthy there — meeting its latency and reliability targets, instrumented well enough to prove it, and hardened to survive real load and real failure
- You own the outcome, not the ticket
- You'll lead a functional area end to end: set its technical direction, make the calls that matter, and pull other engineers along with you
Our take
Cyberattacks are becoming more sophisticated. For example, zero-day cyberattacks leverage vulnerabilities that are unknown even to the users and creators of a system. Tens of billions of dollars are being invested in protection, but OPSWAT delivers security solutions that nip the need for extra cyber defence in the bud.
The company's products focus on threat prevention, enacting a zero-trust mentality to ensure that technology systems are watertight from threats. For example, OPSWAT's MetaDefender platform incorporates advanced malware threat protection to detect vulnerable files and emails, as well as software, before it is even installed.
It’s this philosophy of “Trust No File, Trust No Device” that makes OPSWAT such a robust partner for the likes of AMEX and the United States Department of Justice. In addition to cyber protection products, the company also helps train future cyber defenders through its academy, which has trained 70,000 professionals so far.
