We're partnering with an exciting early-stage startup building next-generation networking and security infrastructure for AI agents. The company is developing a cloud-native platform focused on secure communication, distributed systems, and scalable infrastructure.
We're looking for talented Backend Software Engineers to join a growing engineering team and help design, build, and scale the company's core platform.

- Work on backend systems supporting networking, security, and communication between services.
- Troubleshoot performance, reliability, and scalability challenges across distributed environments.
- Collaborate with a small engineering team to build new features and take products from concept to production.
What We're Looking For:
- 3+ years of professional software engineering experience, with a strong backend development focus.
- Golang experience preferred, but open to engineers with strong object-oriented programming backgrounds in Java, Python, C++, or similar languages.
- Hands-on Kubernetes experience, including deploying, managing, or developing containerized applications.
- Strong AWS experience, with an understanding of cloud infrastructure and services.
- Experience designing and developing REST APIs, microservices, or distributed backend applications.
- Solid understanding of software engineering fundamentals, data structures, and system design.
- Experience building and maintaining production software.
- Ability to work independently and thrive in a fast-paced, early-stage environment.
Nice to Have:
- Experience with networking infrastructure, proxies, API gateways, or load balancers.
- Familiarity with Layer 4–7 networking concepts.
- Experience with cloud security, authentication, authorization, or identity management.
- Exposure to Kubernetes networking, service meshes, or infrastructure automation.
- Experience with AI agents, LLM infrastructure, or emerging AI technologies.
- Previous experience working at a startup or on a small engineering team.
