DevOps engineer

About us

Hero Labs mission is to solve real-life problems with truly smart technology.  We combine world-class academic research, award-winning IoT/smart home expertise and elegant design into smart, helpful products that enhance people's lives.

After a couple of years of research and development, Hero Labs is ready to launch its first commercial product - Sonic, the smartest leak protection system ever created.

Sonic monitors the flow of water through a whole home or office and checks it up to half a million times a day to detect problems like burst pipes, slow leaks or dripping taps. It's even smart enough to recognise individual appliances and provide a breakdown of how you use water at home, so you can save water, save money and save the planet, too.

We're an ambitious, exciting startup with a fantastic product and offices in Poland and the UK. We've got an investment in the bag and a carefully picked team of exceptionally driven, motivated people. Now, all we need is you: an extremely talented DevOps to help us bring Sonic to the world.

Your role

This is a busy role in a startup company, and you will need to be comfortable working in a dynamic environment. You should be confident with handling different tasks and switching context when needed, although we will try to minimise this. One week, you might be guiding our data scientists to communicate with an SQL DB or DynamoDB, and another week you might be designing a disaster recovery, working on infrastructure or implementing a new CI/CD pipeline. You must also be comfortable with being available for on-call duty when required.

Our tech stack

• Our backend is written mainly in Elixir and Ruby
• Data science uses Python
• We use various TypeScript lambda functions
• We are building, testing and releasing our software in GitHub Actions
• We use Terraform, HashiCorp Vault and Ansible
• We use Docker but we would love to use it everywhere
• Almost whole infrastructure is in AWS, where we particularly use ECS, S3, DDB, IoT, Kinesis, Lambdas etc
• Our databases are PostgreSQL and InfluxDB
• Logs are in Logz, metrics in Prometheus and visualisation in Grafana

Your main tasks

• Take ownership of AWS and its infrastructure
• Continuously improve the reliability, stability, and performance of the infrastructure
• Ensure infrastructure security and perform a routine security audit
• Build a new monitoring and alerting system

This role will be exciting and challenging as we are working with a live system with real users. Your role will support us in designing and implementing better CI/CD, improving our security, building APIs for our partners, or using better monitoring and logging tools. 

We work from our offices in Lodz, Poland and London, England. You should be willing to travel to our office in Lodz, with the frequency depending on your home location.

We're not a corporation. We are a fast-paced, lean & mean start-up, and you must be comfortable working in such an environment.

• Must have experience with building a system that runs 24/7
• Must have experience with implementing CI/CD
• Must have experience with monitoring tools
• Must have a good knowledge of AWS
• Previous experience in managing infrastructure-as-code and/or terraform will be helpful
• Good programming skills in Shell, Python or TypeScript
• Good knowledge of microservice architecture
• Good knowledge of APIs in general
• Knowledge of Git, Docker, SQL
• Must be able to communicate well and take ownership and responsibility of all tasks
• Willing to be on-call outside of normal working hours
