DevOps / Cloud Platform Engineer v Brno, Česko

Your mission

Role purpose
We're looking for a DevOps / Cloud Platform Engineer to become the third member of our DevOps team. One of us owns the AWS architecture and security, the other keeps our fleet of on-site edge controllers running with Ansible. You'll focus on the cloud side: working on the AWS infrastructure and the Terraform that describes it, gradually taking ownership of selected services, keeping our CI/CD and deployments reliable, and making life easier for our developers.
We run a large AWS environment with a big Terraform codebase, so there's real scale but still plenty of room to shape how things are done. We're open to both mid-level and senior candidates. If running and improving production cloud infrastructure at that scale sounds like fun, let's talk.

What You'll Be Doing
Taking ownership of selected services and evolving our AWS infrastructure in Terraform: refactoring, modularizing and keeping a large codebase clean and predictable.
Running and improving our container platform on ECS Fargate, plus the serverless and data services around it (Lambda, IoT Core, Kinesis, Step Functions, RDS).
Building a developer self-service platform: reusable Terraform modules and service templates, so teams can launch a new service without writing raw Terraform.
Standardizing CI/CD in GitHub Actions across our repositories with reusable workflows and safe deployment patterns.
Contributing to architecture decisions for the next stages of Podium together with the development teams.

Tech Stack You'll Touch
Cloud: AWS (ECS Fargate, Lambda, RDS, IoT Core, Kinesis, Step Functions, S3, CloudWatch)
IaC & CI/CD: Terraform, GitHub Actions, Docker
Observability: CloudWatch, Grafana, Sentry
Access & edge: Cloudflare, Okta
Scripting: Python, Bash

Your profile

You definitely should have:

• 3+ years of hands-on DevOps or cloud engineering, mostly on AWS, in production.

• Solid Terraform beyond the basics: writing modules, managing state, refactoring an existing codebase without breaking things.

• Observability tooling (Grafana, CloudWatch, Sentry).

• Experience running containers in production

• CI/CD experience with GitHub Actions or a similar tool.

• Good Linux and networking fundamentals (VPC design, load balancing, security groups).

• Scripting skills in Python or Bash.

• A security-minded approach

• Professional working proficiency in English (we work daily with UK colleagues).

Bonus points if you've worked with:

• Internal developer platforms, service templates or self-service tooling for dev teams.

• Terraform automation platforms such as env0, Spacelift, or similar

• Serverless and event-driven architectures (Lambda, Step Functions, Kinesis, IoT Core).

• Ansible.

• AWS certifications (Solutions Architect, DevOps Engineer).

• Energy systems, IoT or data-heavy platforms.

• Data analytics platforms (e.g. Databricks, Snowflake or similar).

Want to build the cloud platform behind batteries and solar plants that help decarbonize the grid? Want to work in a small team where your decisions actually stick? This might be the place.

Why us?

• Flexible working hours (hybrid model with offices in Brno, Brumov-Bylnice, and home office).

• Motivating salary package.

• Quarterly bonuses.

• Exciting Industry Sector which is full of innovations.

• Professional growth, educational support, and team growth opportunities.

• 25 days of vacation and 5 sick days.

• Human-centric approach and team support.

• Opportunity for international training.

• Meal and phone allowance.

• Company events (Czech and Great Britain colleagues).

• Multisport, fruit days.
