Platform Engineer

Job#: 3025644

Job Description:

Role: Platform Engineer

Duration: Multi-year contract

Location: Hybrid - 4 days/week onsite in SE MI

Job Description:

Platform Engineering builds shared services, APIs, and developer tooling that enable engineering teams to deliver value safely, reliably, and quickly. This role is focused on software development, with an emphasis on building high-quality APIs, automation, and internal platform tools, supported by working knowledge of cloud, DevOps, and SRE practices.

You will design and deliver platform capabilities that are treated as products-secure, reliable, well-documented, and easy for other teams to adopt.

What You'll Do

• Design and build internal and customer-facing APIs and services that are secure, reliable, and well-documented
• Develop developer tools and platform services that improve developer experience (DX), including templates, CLIs, libraries, service scaffolding, and automation
• Apply strong engineering fundamentals, including test-driven development, code reviews, CI, and safe deployment practices
• Engineer for operability by implementing structured logging, metrics and tracing, health endpoints, and actionable alerts
• Collaborate with platform and product teams to standardize cross-cutting patterns such as authentication and authorization, secrets management, configuration, resilience, and API versioning
• Participate in incident response and reliability improvements, helping teams reduce defects and operational risk

Required Qualifications

• Strong software engineering experience delivering production services and APIs, including design, implementation, testing, and operations
• Proficiency in at least one backend language such as Java, Go, C#, Python, or TypeScript
• Experience designing and managing APIs throughout their lifecycle, including versioning, backward compatibility, pagination, and error modeling
• Strong testing discipline (unit, component, and integration testing) with confidence refactoring code safely
• Working knowledge of cloud-native delivery, including containers, CI/CD pipelines, and operating services in a cloud environment
• Ability to debug issues across layers (application, runtime, and platform) using logs, metrics, and traces

Preferred Qualifications

• Experience building and maintaining platform APIs with an internal product mindset (usability, documentation, adoption, and support)
• Experience with event-driven and asynchronous architectures, including queues, pub/sub, idempotency, and reliability patterns
• Security experience, including OAuth/OIDC concepts, least-privilege access, threat modeling, and input validation
• Experience improving reliability using SLOs and reducing operational toil through automation
• Experience working with Kubernetes and infrastructure as code in partnership with platform and SRE teams

How We Work

• Build small, ship often: Incremental changes with clear acceptance criteria and fast feedback
• Quality is non-negotiable: Strong testing, clear design, observability, and secure-by-default patterns
• Operate what we build: Ownership includes production support, documentation, and continuous improvement

What Success Looks Like

• Platform APIs and tools are adopted because they are reliable, well-documented, and easy to integrate
• Developers spend less time on undifferentiated work (setup, pipelines, troubleshooting) and more time delivering features
• Incidents decrease due to improved operability, safer releases, and consistent engineering standards

Required Skills

• Python: Experience building and shipping production-grade services or internal tools, including testing and error handling
• Go: Ability to write idiomatic Go for reliable backend APIs or platform services
• REST APIs: Proven experience designing well-structured, versioned APIs with clear documentation and lifecycle management
• Cloud Infrastructure: Working knowledge of running services in a cloud environment, including CI/CD, health checks, logging, and configuration
• Docker: Experience containerizing services and integrating Docker into standard delivery workflows

Preferred Skills

• Google Cloud Platform: Hands-on experience deploying and operating services on Google Cloud Platform
• Kubernetes: Experience deploying and managing workloads with Kubernetes in collaboration with platform/SRE teams
• Agile Software Development: Experience working in short, iterative cycles with frequent delivery and feedback
• Endpoint Security: Experience applying security best practices at the API and service level

Experience & Education

• Experience Level: Engineer 3
  • 6+ years overall IT experience
  • 4+ years in software development
  • Practical experience in at least two programming languages, or advanced expertise in one
• Education: Bachelor's degree required
