About the DevOps Lead Position

We are building a new product from the ground up using a modern AWS Serverless-first architecture, and we are looking for a DevOps Lead to establish and grow our DevOps function. This is a leadership role: you will build and lead the DevOps team, define the infrastructure vision, standards and roadmap, and own the reliability, security and cost-efficiency of the platform end to end.

The stack is built around CloudFront + S3 (Frontend), AppSync + Lambda (Backend API), Aurora PostgreSQL + MongoDB (Databases), with multi-tenant authentication managed at the DB layer. As the founding DevOps Lead, you will set technical direction while partnering closely with Engineering and Product leadership and reporting to the Engineering Manager / CTO.

Responsibilities

1.Team Leadership & DevOps Function Building

    • Build, lead and grow the DevOps team — hiring, onboarding, mentoring and performance management.
    • Define the DevOps vision, standards, runbooks and operational playbooks.
    • Establish a strong DevOps culture, shift-left security and engineering best practices across teams.
    • Own the infrastructure roadmap and report status, risks and roadmap to the Engineering Manager / CTO.
    • Plan capacity, resourcing and workload distribution; set OKRs and drive delivery for the team.

2.Infrastructure Strategy & Architecture

    • Oversee multi-tenant architecture patterns at the database and API layer.

3. AWS Serverless & Cloud Platform (technical direction)

    • Direct serverless infrastructure across AppSync, Lambda, CloudFront, S3, EventBridge/SQS/SNS and Step Functions.
    • Oversee database infrastructure: Aurora PostgreSQL Serverless v2, AWS DocumentDB and ElastiCache (Redis).
    • Guide authentication & multi-tenancy — Cognito / JWT / Lambda Authorizer, tenant isolation at network, IAM and data layers.

4. CI/CD, Reliability & Observability

    • Set CI/CD pipeline strategy (GitHub Actions / GitLab CI) and deployment strategies (blue/green, canary, rollback gates).
    • Establish monitoring and observability standards (CloudWatch, X-Ray, Logs Insights, alerting).
    • Own reliability, incident response and on-call processes for the platform.

5. Security, Compliance & FinOps

    • Define security standards — IAM least-privilege, WAF, GuardDuty, KMS, Secrets Manager, AWS Config / Security Hub.
    • Integrate security scanning into CI/CD (e.g. Checkov, Trivy) and drive continuous compliance.
    • Lead serverless cost optimization (FinOps) and platform improvement initiatives.

6. Collaboration & Stakeholder Management

    • Partner with development, product and security teams to embed DevOps culture and shift-left practices.
    • Communicate infrastructure status, risks and roadmap clearly to engineering and business leadership.
