Principal Software Engineer, Core Infrastructure

Leads development and begins architecting components of scalable, elastic distributed systems. Defines and enforces scalability requirements for owned components; optimizes code and data paths for high‑throughput, hyper‑scale workloads; and leverages data plane platforms for large‑scale retrieval, storage, and processing. Designs fault‑tolerant, in‑service‑upgradable systems using redundancy, replication, failover, and policies for partitions, applying load‑shedding, throttling, and rate‑limiting to handle network unreliability while meeting SLOs. Establishes KPIs and telemetry; builds proactive dashboards and alerts; and designs complex validation (fault injection, brownouts), replication, and synchronization for correctness and durability. Proactively diagnoses and resolves production issues, mentors peers, and ensures operational readiness. Implements robust security controls, executes remediation, maintains compliance documentation, and develops IaC and automation that enable safe patching, updates, and rollbacks within change‑management plans.

Responsibilities

System Scalability

• Develops distributed-system components supporting horizontal and vertical scaling through distributed-state-management tools.

• Uses data-plane platform components for large-scale retrieval, storage, and processing.

• Implements performance and load testing; designs, develops, tests, deploys, and maintains production software and cloud services.

   

Reliability, Correctness, and Availability
 

• Builds fault-tolerant components that withstand in-service updates through redundancy, replication, and automatic failover.
• Applies recovery-oriented computing; implements retries, circuit breakers, and timeouts for network unreliability.
• Implements tests, alarm configurations, fault-injection, and brown-out scenarios to detect failures and validate correctness.
• Implements standard data-replication and synchronization techniques to preserve integrity and availability.

• Drafts and executes runbooks and operational procedures; builds dashboards, telemetry, and alerting for component health. 

Operations, Security, and Change Management
 

• Diagnoses, debugs, and resolves component issues; implements strategies to prevent interruptions and avoid customer maintenance windows.
• Designs, implements, and maintains automation scripts, tooling, and IaC for troubleshooting and cloud-infrastructure management.
• Participates in operational-support rotations, incident response, root-cause investigations, and follow-up improvements.
• Applies advanced multi-tenant security measures, including encryption and access controls; implements remediation plans.

• Ensures compliance with relevant industry standards and regulations, maintains current documentation, and follows change-management plans for patching, updates, and rollbacks.

Collaboration and Delivery
 

• Partners with product managers, architects, and engineering teams to translate requirements into technical solutions.
• Creates technical and operational documentation; drives projects forward and mentors junior team members.

Education and/or Experience
 

8 years of software-development experience; or

Bachelor’s degree in Computer Science, Computer Engineering, Software Engineering, Electrical/Electronics Engineering, Computer/Information Systems, Information Technology, Telecommunications, Mathematics, Physics, or related field, plus 4 years of software-development experience; or

Master’s degree in those fields, plus 2 years of software-development experience; or

Doctorate in those fields.

 

Skills and Experience

• Demonstrated ability or knowledge in distributed systems; prototyping; computer-science programming; software engineering; web development; innovation; cross-functional collaboration; information vulnerabilities; operating systems; API development and integration; applied algorithm engineering; and source control.

• Proficiency in Java, Python, Go, C++, C#, or a similar language.

• Strong data structures, algorithms, object-oriented design, software-engineering, problem-solving, communication, and collaboration skills.

• Experience building, testing, and debugging production-quality software; familiarity with REST APIs, databases, cloud applications, and agile methodologies.
