Job description

Do you enjoy designing cloud infrastructure that is secure, scalable and built to last?

And do you want to own changes end to end, from the first conversation with stakeholders to a verified production rollout?

DNA.inc is looking for a Senior Cloud Engineer with solid Java and Spring Boot skills to join a perimeter and platform team for one of our major digital partners. The team owns the layer that sits between internal services and their consumers: API contracts, edge configuration, telemetry, and the AWS infrastructure behind them. Your work keeps that layer reliable and secure for the many teams that depend on it.

About the job

Most of the work is infrastructure as code and system design on AWS, combined with building and running Java and Spring Boot services. You'll be equally comfortable in a Terraform module and in a Spring Boot codebase. You will usually be the primary or secondary owner of a project, working directly with consumer teams to understand what they need and turning that into well-reasoned technical decisions.

In this role, you'll:

• Design, build and evolve AWS infrastructure with Terraform (Lambda, ECS, S3, IAM, API Gateway, Cognito and more)

• Standardize API contracts across the platform and implement consumer-requested capabilities, such as header passthroughs, pagination and API versioning

• Build and run Java services (Java 21+, Spring Boot), for example an event forwarder that fans out telemetry streams to approved consumer destinations without losing events

• Write ADRs that lay out options and trade-offs for decisions that set technical direction, and split proof-of-concept work into manageable chunks

• Work with consumer and stakeholder teams to investigate requirements, agree on an approach and coordinate dependencies

• Take changes from intake to production and verify that they work there

• Review code across several of the team's projects

About you

To be considered for this position, we expect you to have:

• 5+ years of professional cloud, platform, or backend engineering experience

• Strong hands-on experience with Terraform

• Solid experience with AWS services, such as Lambda, ECS, S3, IAM, API Gateway, and Cognito

• Strong, production experience with Java (ideally 21+) and Spring Boot, building and running services

• A good understanding of designing scalable and secure services and systems

• The ability to drive a project independently, including in areas outside your direct expertise

• Comfort talking to stakeholders and consumer teams directly when a project needs it

It would also be great if you have experience with any of the following. They are not required, and you can learn them on the job:

• TypeScript

• Multi-region or active-active architectures

• Authentication and identity implementations

• Edge security, such as WAF and private networking

• Distributed and event-driven systems, such as telemetry or event streaming
