We’re looking for a Senior Full-Stack Engineer who loves shipping fast, owning big pieces of the stack, and building modern cloud services from the ground up. If TypeScript is your home base ,you know AWS inside out and Terraform & Pulumi are your favorite IaC, you’ll fit right in. You’ll work across product and infrastructure, help level up our engineering practices, and take a key role in shaping how we build, deploy, and scale. Team-leading and mentoring skills are highly valued.

What You’ll Do

·       Lead and mentor a small, high-impact full-stack team (backend, frontend).

·       Build product-facing microservices and full-stack features in TypeScript.

·       Design and own AWS infrastructure using Pulumi/Terraform/CDK with a strong focus on automation and scalability.

·       Drive features end-to-end, from idea to production, and help define engineering standards across the board.

·       Keep our environments rock-solid — secure, observable, cost-efficient, and resilient.

·       Debug tricky production issues across both infrastructure and application layers.

·       Continuously improve how we build: CI/CD, DevOps, documentation, workflows, and everything in between.

·       70-80% Hands On

What You Bring

·       5+ years hands-on TypeScript experience — MUST

·       2+ years with Pulumi or Terraform — MUST

·       5+ years building and running real systems on AWS — MUST

·       Strong CI/CD background (GitHub Actions, GitLab CI, CircleCI, etc.).

·       Deep understanding of core AWS services (EC2, ECS, Lambda, VPC, IAM, RDS, CloudFront, S3, Route 53).

·       Solid knowledge of AWS networking: VPCs, subnets, routing, NATs, security groups, NACLs.

·       Strong security mindset: IAM roles/policies, secrets management, least privilege.

·       Familiarity with monitoring/observability tools (CloudWatch, Datadog, Prometheus, Grafana).

·       A “get it done” attitude, high ownership, and comfort moving fast.

Bonus Points

·       Experience with serverless, microservices, or event-driven architectures.

·       Exposure to SOC2/ISO frameworks or cloud governance.

·       Experience with DevSecOps tools (Snyk, GuardDuty, Inspector, Prisma Cloud).

·       Knowledge of AWS cost-optimization best practices.

Location & Work Style
