Principal Core Infrastructure Engineer

Architecture and Delivery

• Lead significant systems and initiatives from problem definition and design through implementation, rollout, adoption, and production validation.
• Translate scalability, security, reliability, and business requirements into clear technical designs and execution plans.
• Make sound tradeoffs involving availability, consistency, latency, throughput, durability, cost, and operational complexity.
• Design for partial failures, retries, duplicate requests, mixed-version deployments, dependency degradation, and regional disruption.
• Write and review secure, maintainable, well-tested Java code.
• Define service contracts, compatibility requirements, migration plans, validation strategies, and rollback criteria.

Scalability and Operational Excellence

• Establish capacity models, performance objectives, scaling strategies, and load-testing plans for high-throughput services.
• Design effective throttling, load shedding, backpressure, caching, concurrency, and failure-recovery mechanisms.
• Define useful service indicators, objectives, metrics, alarms, dashboards, runbooks, and deployment safeguards.
• Lead complex incident investigations and convert recurring failures or manual procedures into automation and preventive engineering improvements.
• Serve as a technical escalation point for problems that cross application, infrastructure, network, or organizational boundaries.

Technical Leadership

• Provide architectural direction in one or more critical areas such as routing, authentication, private connectivity, runtime performance, observability, or deployment infrastructure.
• Decompose broad initiatives so multiple engineers can own meaningful work while maintaining architectural consistency.
• Mentor engineers through design, code review, delivery, and incident response.
• Raise engineering quality through reusable systems, tools, standards, and operational practices.
• Contribute to hiring and help identify architectural investments, platform gaps, and reliability risks for the team roadmap.

Cross-Team Execution

• Align SPLAT and partner teams on technical decisions, responsibilities, dependencies, and rollout plans.
• Communicate complex designs, tradeoffs, risks, and progress clearly to engineers and leaders.
• Make progress under ambiguity by separating facts, assumptions, reversible decisions, and external dependencies.
• Adjust direction when production evidence or new technical information invalidates earlier assumptions.
• Use modern development and AI-assisted tools responsibly to improve engineering quality and productivity.

• Bachelor’s degree in Computer Science, Computer Engineering, or a related field, or equivalent practical experience.
• 8+ years of experience designing, building, and operating production backend or platform services.
• Strong development experience in Java or another modern object-oriented language.
• Strong understanding of distributed systems, concurrency, fault tolerance, and production operations.
• Experience leading substantial technical initiatives across multiple engineers or teams.
• Demonstrated ability to diagnose complex production issues and improve service reliability.
• Strong written and verbal communication skills., * Experience with high-throughput, low-latency services, HTTP, networking, proxies, or API gateways.
• Experience with authentication, authorization, TLS, certificates, private connectivity, or multi-tenant security.
• Experience with throttling, load shedding, caching, and capacity planning.
• Experience with cloud infrastructure, Kubernetes, infrastructure as code, CI/CD, and deployment automation.
• Experience improving a broader engineering organization through mentoring, shared tooling, or technical standards.
