Principal Software Engineer

Job Description

About You

You work backward from users and operational needs. You care about building usable, reliable software that helps engineering and operations teams reason about complex physical infrastructure. You can learn and model domain concepts such as fabrics, devices, racks, ports, pluggables, patch panels, cable paths, data halls, and topology rules, while keeping the focus on clean software abstractions and maintainable systems. You have strong communication skills and can clearly explain complex technical concepts, tradeoffs, and system behavior. You work well across disciplines. You can lead conversations with engineers, product managers, infrastructure specialists, network engineers, and partner teams, and translate ambiguous requirements into practical software designs. You are comfortable with ambiguity. You have a strong sense of ownership and can drive projects from design through implementation, rollout, validation, and production support. You are comfortable working across different layers of the stack, including APIs, services, persistence, validation logic, tooling, and operational workflows.

Responsibilities

Responsibilities

Design, build, and operate highly available services that support OCI Layer 1 network modeling and infrastructure lifecycle management. Drive development of core platform capabilities, including topology modeling, workflow orchestration, validation, reconciliation, API design, and integration with downstream systems. Work with large and complex data models representing infrastructure resources, physical topology, logical connectivity, network devices, ports, racks, rooms, cable paths, configurations, and operational state. Build software that converts network infrastructure intent into reliable, validated system state. Develop validation frameworks and tools that compare intended logical topology against physical cabling, generated connections, cutsheets, or operational records. Develop tools and services that improve correctness, traceability, observability, and operational efficiency for data-center network buildout and handover. Debug complex production issues across service boundaries, data pipelines, APIs, validation logic, asynchronous workflows, and infrastructure data sources. Partner with cross-functional teams to understand requirements, define technical designs, and deliver production-quality solutions. Mentor engineers, review designs and code, and help raise the engineering bar for maintainability, testing, reliability, and operational excellence.

Qualifications

7+ years of software engineering experience. BS or MS degree in Computer Science or equivalent experience. Proficient in Java, C++, C#, or similar object-oriented languages. Strong knowledge of data structures, algorithms, operating systems, and distributed systems fundamentals. Experience designing and building REST APIs and service-oriented systems. Strong troubleshooting, debugging, and performance tuning skills. Experience owning software through the full lifecycle: design, implementation, testing, deployment, and production support. Ability to reason about complex systems, data models, state transitions, validation rules, and service contracts. Experience working with complex domain models, relationship-heavy data, and operational workflows.

Preferred Qualifications

Experience building large-scale cloud infrastructure, control-plane, provisioning, inventory, orchestration, network automation, or infrastructure management systems. Experience with microservices and distributed systems. Experience with durable workflow systems, reconciliation loops, validation frameworks, graph-like data models, topology modeling, or rule-driven systems. Experience building software using Java, Python, Shell scripting, JavaScript, or similar technologies. Strong object-oriented design and programming skills. Experience with containerized applications, Docker, Kubernetes, or similar platforms. Working familiarity with networking, compute, storage, or data-center infrastructure concepts. Familiarity with infrastructure concepts such as devices, ports, racks, fabrics, cabling, optical transceivers, patch panels, physical topology, or data-center build workflows. Experience designing RESTful APIs and production service contracts. Experience delivering and operating large-scale, highly available distributed systems. Experience with observability, incident response, operational tooling, and production debugging. Experience building multi-tenant, virtualized, or cloud-scale infrastructure systems is a strong plus.
