As one of our QA Engineers, you'll be the guardian of product excellence - thinking like a hacker, testing like a detective, and ensuring our complex systems work flawlessly in the wild. You'll go beyond finding bugs to anticipating the unexpected: edge cases, weird component interactions, and those "no user would ever do this... but what if?" scenarios that separate good products from great ones.
What You'll Own:
* Design battle-tested strategies that catch issues before customers do
* Build automated test suites that scale with our ambitions
* Hunt down bugs across complex component interactions and configurations
* Partner with dev teams to ship quality at speed
* Be the voice of risk assessment when it matters most
You Should Have:
* Critical thinking that connects dots others miss
* Deep web tech knowledge (HTTP/HTTPS, DNS, SSL/TLS, CDN)
* Automation chops (Python, JavaScript, Bash)
* Experience with test methodologies and writing bulletproof test cases
* Debugging skills that turn logs into insights
* Communication skills that turn complex issues into clear actions
Why Join?
You'll be testing cybersecurity products that defend critical infrastructure against DDoS attacks – a single bug could mean the difference between stopping an attack in <10 seconds or watching a bank, power grid, or hospital go offline. This isn't just QA – it's cyber defense at the highest level.
If breaking unbreakable systems and ensuring bulletproof security for critical infrastructure sounds like your kind of challenge, come lead, code, and conquer with us: https://www.link11.com/en/jobs/qa-engineer-remote-first-f-m-...

I tried applying via the careers terminal, but it stays in shell mode on my end and doesn’t start the interactive flow (likely a browser or JS init issue), so I’ll also reach out via email.
The work you’re doing around decentralized coordination and sandboxed execution is exactly the kind of systems engineering I’m interested in.
Legion Health is building the AI-native operations layer for mental health care. We run our own psychiatric practice and use AI agents to handle the complex "backend" of healthcare—scheduling, intake, documentation, billing, and risk detection. We have $3M+ ARR, $7M+ raised, and our infrastructure currently supports 2,000+ patients with only one human support lead.
We're hiring a Founding Engineer to own our backend and agent systems end-to-end. This is not a "wrapper" role; you will be architecting the state machines and event streams that turn clinical intent into reliable operations.
The Role:
Build AI Co-workers: Implement agents with tool use, memory, and safety rails that act as trustworthy teammates for clinicians.
Event-Driven Architecture: Design the schemas and workflows (Node.js/TypeScript/Postgres) that encode how psychiatric care operates.
High Impact: Your work lands in real clinical workflows immediately, directly improving patient access and care quality.
Tech Stack: Node.js, TypeScript, Supabase (Postgres), AWS (ECS/Lambda), Next.js 15, OpenAI/Anthropic.
Offer:
Comp: $130k–$190k base + significant early equity (0.2%–0.8%).
Location: San Francisco (In-person).
Process: Intro -> Systems Deep Dive -> Practical Work Trial (No Leetcode) -> Onsite. We move fast (7-10 days).
Email me at yash@legion.health if you have questions or if you're super cracked and I have to know about you.
