Platform / DevOps Engineer

About Ember
We're building the future of public transport — convenient, affordable, connected and zero-emission. Our goal is to make it easier and more enjoyable to get from A to B with Ember than it is with your own car.
We’re a tech company, not a traditional bus operator. We've built a platform that coordinates our entire operation – everything from monitoring vehicles and controlling chargers to selling tickets and calculating ETAs. This allows us to use electric buses more intensively than anyone else in the world, leading to a massive emissions reduction. It also helps us provide a much better passenger experience, with innovative features like demand-responsive stops.
We’re still tiny, with two routes and 24 buses. The challenge is to scale this 100x whilst staying lean, increasing efficiency and delivering an even better product experience. We’ve recently raised equity from some of Europe’s leading climate VCs and are looking for mission-driven individuals who can help take us to the next level.
Our tech stack
Our systems drive everything we do including booking tickets, tracking buses, controlling chargers, calculating ETAs, monitoring traffic and keeping passengers informed. We rely on the following tools and technologies:
Python for our application codeReact for our frontendPostgres for data storageRedis for cachingKafka for stream processingBetter Uptime for alertingCloudwatch and Datadog for monitoringSwiftUI for our Driver iOS AppAWS, Terraform, Gitlab CI/CD, Docker and ECS to deploy and run our servicesFlutter for our on-board server running Android, which handles concession ticket validation with more on-board experience features to come.
What you will do
You role will be broad and could touch on any of the following or similar projects.
Enhancing our testing anddeployment pipelines,such as adding automated load testing to validate changes before they are deployedDeveloping a more sophisticated canary deployment strategy, with associated monitoring and rollback functionalitySetting up a specialised database for analytics and corresponding data pipelinesImproving the observability of the systems running on our busesand improving their deployment pipelinesDeveloping and maintaining our security postureContributing to application features
Your work will be making a difference to our planet by helping more people travel on zero-emission public transport.
