Software Engineering Intern @ Corridor

About Corridor

Software development is becoming autonomous. The fastest teams already work this way, and at Corridor, we are leading the way on secure development as the rest of the industry follows.
Security tools were designed for a world where a person wrote the code and a person reviewed it. That's changing quickly. Corridor is securing software factories. We are the security solution for software that builds itself at every level of autonomy. We are preventing vulnerabilities as agents write code, and guiding teams to help decide what's safe to ship.

We're a small, talented team, led by Jack Cable (Former CISA - Secure by Design), Ashwin Ramaswami (Former CISA, Stanford, and Schmidt Futures) and, Alex Stamos (Former CISO of Facebook, Yahoo, SentinelOne).
Corridor is backed by Conviction, with a $25M Series A led by Felicis and our customers include ElevenLabs, Lovable, Mercor, and Langchain.

What You'll Be Doing

• Build products at the forefront of AI security, helping developers ship AI-generated code safely and confidently.

• Own features end-to-end: from idea and architecture through production, customer feedback, and iteration.

• Work closely with customers to understand their workflows and turn complex problems into intuitive products.

• Build AI-powered systems using LLMs and coding agents to solve novel security challenges.

• Collaborate across engineering and product in a small, high-performing team where you'll have real influence on what we build.

• Move quickly, experiment often, and shape both our product and engineering culture as we scale.
  

What We're Looking For

• Proven experience building and shipping production-grade full-stack applications using a range of languages eg. TypeScript, React, Python, Go, with end-to-end ownership from concept to production

• Strong product instincts and a customer-first mindset, turning ambiguous problems into simple, impactful solutions

• Comfortability navigating complex, ambiguous challenges, bringing clarity and making sound technical decisions with minimal direction

• Experience working autonomously in fast-paced startup environments with a strong bias toward action

• Deep full-stack expertise, with the ability to build scalable backend systems and polished, high-performance user experiences

• Experience with modern infrastructure tools including AWS, Terraform, Docker, and ECS/Kubernetes

• Hands-on experience building and productionizing AI systems, including LLMs, coding agents, reasoning models, prompting, fine-tuning, and evaluation frameworks

• Someone excited by cutting-edge AI security challenges and building products that help developers write safer software

• Creative, pragmatic, and comfortable owning features end-to-end-from architecture and implementation through deployment and iteration

• Strong communicator and collaborator with a track record of shipping high-quality products.

Why Corridor?

• Help define one of the fastest-growing categories in software. AI is transforming how code is written, and we're building the security layer that enables it.

• Solve hard, meaningful problems. Work on novel AI, security, and developer experience challenges without an existing playbook.

• Make an outsized impact. As part of a small, ambitious team, you'll have real ownership and see your work directly influence customers and the future of the company.

• Be independent of the foundation labs. We are entirely independent of the foundation labs. Our goal is not to sell you tokens, and certainly not to over-hype or create fears about AI. We're practical! We empower security teams using open and closed models, local and cloud agents.

About Our Leadership

• CEO Jack Cable is a top-ranked bug bounty hunter who previously led Secure by Design at CISA.

• CTO Ashwin Ramaswami is an engineer who has built large-scale systems at Skiff, Caldera, and Nooks, and has published research in AI and foundation models at Stanford.

• CSO Alex Stamos is the former CISO of Facebook, Yahoo, and SentinelOne and a current lecturer at Stanford University.
