Responsibilities: 

• Technical Leadership: Lead the design and delivery of large-scale features, driving architecture, implementation, and long-term maintainability.  

• End-to-End Ownership: Own critical components of Consul across the full lifecycle—from RFC and design through implementation, testing, deployment, and ongoing maintenance. Build alignment across stakeholders and drive initiatives to completion.  

• Engineering Excellence: Raise the bar for code quality and system design through in-depth code reviews, architectural guidance, and mentorship.  

• Production Ownership: Act as a technical lead during on-call rotations, driving resolution of complex production incidents. Diagnose and address performance bottlenecks, reliability issues, and security concerns across the stack.  

• Innovation & Strategy: Evaluate and adopt emerging technologies in the cloud-native ecosystem (e.g., eBPF, zero-trust security, next-gen proxy architectures).  

• Mentorship: Mentor and develop junior engineers through pairing, design discussions, and detailed feedback.  

• Cross-functional Collaboration: Partner closely with Product, Solutions, Support, and the open-source community to shape and deliver on the product roadmap.  

• Open Source Contribution: Contribute to both community and enterprise offerings, balancing the needs of a diverse user base.  

• Release & Quality Ownership: Lead release processes, improving automation and reliability. Drive performance benchmarking and scalability testing initiatives. 

• 6+ years of professional software engineering experience, with a heavy focus on building and operating production-grade distributed systems. 

• Expert-level proficiency in Go (Golang), including strong knowledge of concurrency, memory management, and performance optimization. Ability to design clean, scalable APIs and work with complex system state. 

• Proven track record of building and operating highly available, fault-tolerant, and scalable cloud-native services. 

• Strong, fundamental understanding of network protocols (TCP/IP, HTTP, gRPC), operating systems, and cloud infrastructure (AWS, GCP, Azure, OpenShift). 

• Solid understanding of distributed system concepts, including CAP theorem, consistency models, and consensus algorithms (e.g., Raft, Paxos), with practical implementation experience. 

• Deep experience with containerization and orchestration technologies (Docker, Kubernetes). 

• Excellent problem-solving and debugging skills, with the ability to independently navigate complex, ambiguous challenges.  

• Strong communication skills, with the ability to clearly articulate technical concepts to diverse audiences.  

• Experience with automation and testing strategies, including load, performance, and scalability testing.
