Platform Engineer (AWS)

We're looking for an experienced Platform Engineer to join the Alto Team. As a Platform Engineer at ASG, you will be from a software engineering or infrastructure background and be passionate about building a secure and reliable internal platform to aid developers in building fault-tolerant, scalable and stable applications in collaboration with cross functional development teams.

You will be passionate about developer experience and productivity and have a strong understanding of how to design tools and abstractions through an 'as a service' model that enable developers to focus on problem solving and not battling with infrastructure. What You'll Do

• Support the development teams in their use of AWS services through infrastructure-as-code
• Improve developer experience and productivity through scaffolding, templates & tooling
• Evolve our infrastructure practices and cloud architecture, keeping up with industry trends and emerging technologies
• Ensure non functional requirements such as resilience and scalability are maintained across our services
• Build and maintain developer workflows and platforms to enable continuous testing/integration/delivery
• Maintain an observability stack that allows us to reactively and proactively monitor our systems
• Implement service cataloging and service scorecards through a managed internal developer platform

Our Technology Stack

We believe in using the right tool for the job. Our current stack includes:

• Backend: C#/.NET, TypeScript, Node.js, Apollo GraphQL, MongoDB, SQL Server
• Frontend: TypeScript, React
• Cloud & Infrastructure: AWS (ECS, EC2, S3, Cloudfront, DocumentDB, DynamoDB, Lambda), Terraform, Github Actions, Octopus Deploy
• Observability: Datadog, Cloudwatch
• Architecture: Service orientated architecture,, Micro-Frontends, Event-driven architecture, .NET MVC

• Hands-on experience with AWS (essential), along with solid experience in designing and implementing distributed, cloud-native systems aligned to the AWS well-architected framework
• Strong proficiency in an infrastructure-as-code framework (Terraform is our tool of choice)
• Knowledge of observability patterns and tools
• Spent time using scripting languages for bootstrapping and maintaining systems
• Experience migrating from Windows to Linux environments (our core stack is .Net framework)
• In depth knowledge of different legacy migration/system design patterns
• Practical experience in CI/CD platforms (such as GitHub Actions, Octopus Deploy)
• An understanding of IDPs (internal developer platforms)
• Helped implement continuous/automated testing processes
• Excellent cross-functional and cross-team communication and collaboration skills

Don't worry if you don't check every box! We're looking for passionate engineers who are excited to grow. If you have a solid foundation in platform engineering and/or DevOps/SRE and are eager to learn, we encourage you to apply. We are committed to building a diverse and inclusive team and welcome applications from all backgrounds.
