About the role

We're looking for a hands-on Backend Engineer to help us build and maintain reliable backend services on AWS. You'll focus on APIs, data flows, and integrations that power our web and mobile experiences. Ideal if you've connected third-party platforms like Salesforce, Shopify, and push notification providers (e.g., OneSignal).

What you'll do

  • Build and maintain backend services and APIs on AWS (ECS, ECR, VPC, API Gateway, S3, CloudFront, RDS/Postgres, SQS).

  • Design and operate secure, highly reliable backend infrastructure (VPC networking, containerized services on ECS).

  • Implement integrations with Salesforce (REST/Bulk APIs), Shopify, and push notifications (OneSignal or similar).

  • Write clean, well-documented API endpoints (REST/GraphQL) and maintain clear schema/contracts.

  • Set up basic CI/CD and monitoring; contribute to Infrastructure as Code (CloudFormation/Terraform) with guidance.

  • Ensure security, reliability, and performance basics: authentication/authorization, input validation, caching, logs/metrics/alerts.

  • Collaborate with frontend/mobile teams to deliver features on time and with quality.

Requirements

  • 3+ years of backend development experience (Node.js or Go preferred; Python a strong plus).

  • Practical experience building on AWS (ECS, ECR, VPC, API Gateway, S3, CloudFront, RDS/Postgres, SQS).

  • Comfortable with REST APIs; exposure to GraphQL helpful.

  • Experience integrating at least one of: Salesforce, Shopify, or OneSignal (or similar).

  • Understanding of authentication best practices (OAuth/JWT, IAM basics) and OWASP fundamentals.

  • Clear communication in English and a collaborative, problem-solving mindset.

Nice to have

  • Experience with webhooks, event-driven patterns (SNS/SQS, Redis), and rate limiting.

  • Familiarity with headless CMS (Strapi, Contentful, Sanity, Prismic, Hygraph, WordPress headless).

  • Exposure to Next.js/React integrations and preview environments.

  • Terraform basics and setting up simple CI/CD pipelines (GitHub Actions, GitLab CI).
