Accountabilities - Own a core infrastructure product or subsystem end to end, including design, implementation, deployment, operation, and ongoing improvement. - Define project objectives and measurable success criteria, align technical initiatives with broader business goals, and proactively identify risks. - Translate product requirements and technical specifications into pragmatic designs that address important edge cases without unnecessary complexity. - Build and maintain secure, resilient, high-performing, and cost-efficient infrastructure supporting diverse applications and workloads. - Design, develop, and ship software and developer-facing tooling that improves engineering productivity and reduces operational toil. - Manage infrastructure through code and configuration, primarily using Terraform, while maintaining consistency with broader architectural patterns. - Partner with product engineering teams to design services for scalability, resolve ambiguous technical requirements, and collaborate directly with stakeholders. - Participate in incident response and apply systematic debugging techniques to diagnose issues within your area and across interconnected services. - Improve monitoring and observability while using operational data to identify opportunities for better stability, performance, and reliability. - Apply a security-first mindset to infrastructure and software development, proactively identifying vulnerabilities in your own work and during peer reviews. - Serve as a technical resource for complex infrastructure challenges and mentor engineers through code reviews, pairing, and design discussions. - Facilitate collaboration across engineering and other stakeholder groups on technical architecture, processes, and infrastructure priorities. Requirements - 6–10 years of experience in infrastructure, platform, or backend engineering within primarily cloud-based environments, preferably AWS. - Demonstrated experience owning a significant product, platform component, or subsystem from initial design through production operation and ongoing evolution. - T-shaped technical expertise, with deep specialization in one or two infrastructure domains combined with enough breadth to navigate and contribute across the wider technology stack. - Strong hands-on experience managing infrastructure through code and configuration using Terraform or an equivalent infrastructure-as-code solution. - Deep understanding of cloud infrastructure fundamentals, including networking, load balancing, containerization, Kubernetes/EKS, and distributed systems. - Strong programming skills in Go, Python, or a comparable language, with the ability to build and maintain production-ready software. - Hands-on experience operating Redis or ElastiCache in production, including cluster and shard management, failover behavior, memory eviction policies, and scaling strategies. - Experience with observability technologies such as Prometheus, Grafana, OpenTelemetry, or comparable platforms, together with practical knowledge of performance tuning and incident management. - Strong software engineering fundamentals, including source control, code review, comprehensive testing, edge-case handling, and safe deployment practices. - High level of ownership and autonomy, with demonstrated ability to work effectively when requirements are incomplete or ambiguous. - Strong problem-solving and communication skills, with the ability to explain technical decisions clearly and bring engineers and stakeholders together around solutions. - Strong written and spoken English, including experience producing technical design documents, reviewing pull requests, and communicating project or operational updates. Benefits - Competitive compensation aligned with the hiring location, experience, skills, and market conditions. - Fully remote working environment. - Opportunity to work on infrastructure supporting high-scale, customer-facing technology. - Broad technical ownership across cloud architecture, distributed systems, observability, security, performance, and developer tooling. - Opportunity to collaborate with product engineering, security, and DevOps teams on complex technical challenges. - Strong opportunities for technical leadership, mentoring, and cross-functional collaboration. - Inclusive and collaborative working environment that values diverse experiences, perspectives, and backgrounds. - Candidates must be authorized to work from their home location; visa sponsorship is not provided.
