Senior Platform Engineer

Job Description

The Senior Platform Engineer will lead the development and operation of a unified internal platform (developer portal + feature-flag & experimentation services) that enables engineering teams to self-service common infrastructure, safely release features, and adopt a “paved-road” approach. This role ensures platform standards, automation, security, compliance, and observability are embedded from day one while enabling speed and autonomy across product teams.

Accountabilities:

1.Lead and mentor junior platform engineers in building and maintaining the internal platform.

2.Design, implement, and evolve the developer portal based on Backstage, including catalog, templates, docs, service onboarding, and developer workflows.

3.Architect, deploy, and operate the feature-flagging and experimentation framework usingGrowthBook (or equivalent), enabling controlled rollouts, A/B testing, andmetrics-driven experiments.

4.Define, enforce, and continuously improve platform standards/templates for infrastructure, security, compliance, cost, and observability.Collaborate with Platform Architect, Shared Services Manager, and application teams to align platform roadmap and adoption of the paved-road approach


Responsibilities:

1.Customize Backstage — configure catalog, templates, TechDocs, plugins, CI/CD /infrastructure integrations, onboarding flows, and maintain documentation.

2.Deploy and maintain GrowthBook (or similar) — configure feature flags, integrate SDKs with services, define experiment workflows, manage metrics, and ensure secure, performant flag evaluations.

3.Build reusable “paved-road” templates (infra + code + deployment + feature-flag integration + observability + cost guardrails).

4.Implement observability dashboards, logging, tracing, and alerts for platform services to monitor health, performance, and adoption metrics.

5.Integrate security and compliance checks into platform templates and automation, aligned with CSA best practices and MAS-TRM guidelines.

6.Lead platform onboarding for engineering teams — guide usage of portal/templates/flags, educate on best practices, enforce governance, and gather feedback for continuous improvement.

7.Monitor platform adoption, usage, cost efficiency, flag rollout effectiveness, experiment outcomes, and iterate on tooling.

Experience

• Experience in medium-to-large technology or financial services organizations with complexcloud-native environments and multiple engineering teams; exposure to enterprise-grade developer platforms or internal tooling initiatives.

 Seniority, Skills, Certifications (must-haves)

• Have 8+years of experience in platform engineering or cloud infrastructure.
• Strong expertise in AWS (EKS, RDS, Elasti Cache, IAM, VPC, observability), container orchestration, IaC/CaC, and platform automation
• Hands-on experience with Backstage or similar developer portals and feature-flag/experimentation platforms (GrowthBook, LaunchDarkly, or equivalent)
• Familiarity with security/compliance standards (MAS-TRM, CSA)
• Certifications such as AWS Certified Solutions Architect or DevOps-related certifications are a plus.
