Senior Cloud Software Engineer (TypeScript)

Job Description:

We Dream. We Do. We Deliver.

At Merkle, a dentsu company, we power the experience economy. Whether we’re building the next great app, running CRM at scale for global brands, delivering technology architectures that support millions of users, or providing world-class data, identity, and insights solutions, it’s all in the name of crafting experiences that set brands apart from the competition. Backed by dentsu's legacy of innovation and creativity originating in Japan, we’ve spent over 35 years helping brands build loyalty, drive growth, and connect meaningfully with their audiences.  We’ve been named a global “Leader” by top industry analyst firms in categories as wide-ranging as digital transformation and commerce, experience design, engineering and technology integration, digital marketing, data science, CRM and loyalty, and customer data management. 

Role Overview

We are looking for a highly skilled Backend Engineer to join our core product team. In this role, you will be responsible for designing, building, and maintaining scalable server-side applications and microservices. You will bridge the gap between application logic and infrastructure, leveraging TypeScript, AWS, and Jenkins to ensure our systems are resilient, high-performing, and deployed through robust CI/CD pipelines.

Key Responsibilities

• Application Development: Design and implement high-performance, type-safe backend services using Node.js and TypeScript.
• Cloud Infrastructure: Architect and manage cloud-native resources on AWS (Lambda, EC2, S3, RDS, DynamoDB) using Infrastructure as Code (Terraform or AWS CDK).
• CI/CD Leadership: Own and optimize deployment pipelines in Jenkins, ensuring automated testing, security scanning, and seamless production deployments.
• API Design: Build and maintain scalable RESTful or GraphQL APIs, focusing on security, versioning, and developer experience.
• Database Management: Optimize data models and queries for both SQL (e.g., PostgreSQL) and NoSQL (e.g., MongoDB/DynamoDB) databases.
• Code Quality: Conduct rigorous peer code reviews and maintain high test coverage (Unit, Integration, and E2E) using frameworks like Jest or Vitest.

Technical Requirements

• Languages: Expert-level proficiency in TypeScript and modern JavaScript (ES6+).
• Backend: 7+ years of experience with Node.js and frameworks such as NestJS, Express, or Fastify.
• AWS Ecosystem: Deep hands-on experience with core AWS services (API Gateway, Lambda, SQS/SNS, IAM, and VPC networking).
• DevOps/CI: Strong experience writing and maintaining Jenkinsfiles, managing build agents, and troubleshooting pipeline failures.
• Tools: Proficiency with Docker, Git (GitHub/Bitbucket), and monitoring tools like Datadog, New Relic, or AWS CloudWatch.
• Architecture: Strong understanding of microservices, event-driven architecture, and SOLID principles.

Nice to Have

• Certification in AWS (e.g., Certified Developer or Solutions Architect).
• Experience with Kubernetes (EKS) or container orchestration.
• Familiarity with serverless frameworks.
• Experience with Groovy (for advanced Jenkins pipeline customization).
