Senior Platform Services Engineer
About The Position
The Senior Platform Services Engineer owns the shared platform foundation Radiant’s digital products are built on: authentication and authorization for both internal and external users, observability (OpenTelemetry), and the common service and API contracts that keep delivery consistent and safe. This is a hands-on, foundational role – standing up the authentication layer, observability, core shared services, and delivery guardrails. A core part of the job is converting senior engineering judgment into paved paths and automated guardrails (CI/CD, contracts, standards, and AI-assisted review), so that as the team grows, contributors can deliver production-grade work reliably and with less manual oversight. The charter is deliberately tight at launch – authentication, observability, core shared services, and delivery guardrails. The incumbent is expected to triage incoming requests and defer non-core works, so the platform serves product teams rather than becoming a bottleneck. The incumbent works free from daily oversight, regularly exercising independent discretion and significant decision-making in completing job duties.
Requirements
- Minimum 5 years' experience in software engineering, with significant time in platform, infrastructure, or backend/services roles.
- Deep, hands-on expertise in authentication and authorization — OAuth2 / OIDC, SSO, token and session models (e.g., Cognito, Okta, or Auth0) — including serving both internal and external users.
- Hands-on experience implementing OpenTelemetry / observability (tracing, metrics, logging) and establishing it as a shared standard.
- Proven experience designing and operating shared services, platform-as-a-product, or API/BFF contracts consumed by multiple teams.
- Strong CI/CD, infrastructure-as-code, and cloud experience (AWS and/or Azure), including automated quality and security gates.
- Track record of setting technical standards, reviewing others' code, and mentoring engineers.
- Excellent written communication and the discipline for asynchronous work with distributed teams.
- Proficient in English communication (verbal and written).
Nice To Haves
- Bachelor's degree in Computer Science, MIS, IT, or a related field.
- React/TypeScript front-end platform familiarity (backend-for-frontend, design-system infrastructure).
- Experience enabling distributed teams through guardrails rather than manual oversight.
- Experience with AI-assisted developer tooling (coding agents, AI code review) to raise team throughput and quality.
- Domain experience in logistics, supply chain, or transportation management systems.
- Experience integrating with complex or legacy enterprise systems.
- Security and compliance experience with PII, customer, and partner data.
- Familiarity with Jira, Confluence, and modern collaboration tools.
Responsibilities
- Design, build, and own the shared authentication and authorization layer, serving both internal (employee) and external (customer/partner) users.
- Own observability as a shared capability: OpenTelemetry instrumentation, distributed tracing, metrics, and logging, along with the standards product teams follow.
- Build and productize common platform services and API/BFF contracts consumed across product teams – self-service, documented, and versioned – treating engineering teams as customers.
- Establish CI/CD pipelines, paved-path templates, and automated quality guardrails (type safety, linting, testing, security scanning, and AI-assisted code review) that led distributed teams ship safely.
- Define and maintain integration contracts to existing and legacy enterprise systems of record, abstracting their complexity away from product teams.
- Provide technical leadership, architecture guidance, and code review as headcount increases, aligning contributions to the platform and its shared standards.
- Partner with the Product & Experience Lead on feasibility and the front-end platform / design-system infrastructure.
- Set technical standards and mentor engineers over time, raising the team’s overall quality floor.
- Keep the platform charter tight: triage incoming requests and explicitly sequence or defer work beyond the core v1 (auth, observability, shared contracts, guardrails).
- Perform other platform/engineering tasks as assigned.
Benefits
- Medical, Dental, and Vision insurance (employee and family coverage)
- Company-paid basic life insurance
- Short-Term & Long-Term Disability insurance
- Health Savings Account with company contributions
- Flexible Spending Account options
- 401(k) retirement savings plan with 3.5% employer match
- 80 hours of front-loaded Sick Pay
- 80 hours of Vacation Pay annually, with increases based on tenure
- 7 paid holidays per year
