We are seeking an experienced Senior Software Engineer to help develop and evolve a critical ingress proxy service that serves as the primary entry point to a modern browser security platform. In this role, you will contribute to extending security controls beyond human users to include AI agents, helping organizations protect their digital environments as AI adoption accelerates. You will design, build, and optimize highly available, secure, and high-performance networked systems. Working within a small, autonomous engineering team, you will have significant ownership over technical decisions and projects from initial design through production deployment. You will also help modernize existing infrastructure while maintaining reliability and scalability. This is an opportunity to influence the architecture of security-critical systems in a collaborative, low-process engineering environment.

Design, develop, maintain, and operate the ingress proxy service, ensuring its reliability, scalability, security, and performance.

Extend existing proxy capabilities to support secure traffic management and unified security controls for both human users and AI agents.

Build and maintain production-grade systems using modern systems programming languages, particularly Rust or Go.

Optimize network application performance, focusing on latency, throughput, resource efficiency, and scalable concurrency.

Develop and operate asynchronous services capable of handling high-concurrency workloads while managing backpressure, cancellation, and non-blocking I/O challenges.

Contribute to the modernization and gradual rewriting of legacy systems, ensuring safe migration strategies, controlled traffic transitions, and uninterrupted production operations.

Make sound architectural and technical decisions, balancing performance, security, correctness, and long-term maintainability.

Implement robust testing and verification strategies, including fuzzing, property-based testing, and integration testing, to identify potential vulnerabilities and validate system behavior under failure conditions.

Apply security-oriented engineering practices, including threat modeling, vulnerability prevention, and data integrity protection across distributed environments.

Take ownership of the complete software development lifecycle, from technical design and implementation to deployment, monitoring, and ongoing improvements.

Collaborate with engineers and cross-functional teams to understand customer needs, refine requirements, review code, and deliver effective technical solutions.

Share technical knowledge, communicate architectural decisions, and promote engineering best practices across the team.

Leverage AI and LLM-powered tools selectively to improve productivity while critically evaluating generated solutions for accuracy, maintainability, security, and architectural compatibility.
