Bookbot is a recommerce platform that operates in 9 countries, ships books to 40 countries and has already sold over 10 million books. Every day we sell around 30 000 books and receive a little bit more. We are the 16th fastest growing tech startup in the CEE region.
Who we’re looking for:
- You are experienced platform engineer, with expertise in AWS & Kubernetes.
- You can quickly get up to speed with our infrastructure and help relieve our CTO David by taking over a range of responsibilities.
- You’re not afraid to propose new solutions and can independently choose the most efficient technological strategies for your team.
What is your great advantage - you have some experience in leading a small DevOps team, but you are still very hands on (about 80% of your time).
Your responsibilities (on top of being a platform engineer):
- Have a clear overview of what’s happening in the team and the broader context.
- Ensure the delivery of results that align with requirements and priorities.
- Regularly report to the CTO and sync with the Product Manager.
- Represent the entire team and be the main contact for the Platform team.
- Organize team demos/presentations.
- Assist Product with ticketing and estimations.
- Help manage sprints to ensure everything is well planned and completed on time.
- Moderate daily stand-ups.
Current and upcoming Platform team projects:
- Kafka Optimization & Reliability
- Designing and managing Kafka consumers with auto-distribution across a worker pool
- Implementing circuit breakers and consumer-based topic control
- Leading zero-downtime migration to self-managed Kafka using Strimzi and MirrorMaker
- CDC with Debezium
- Streaming data from MySQL to Snowflake (including audit logs)
- Implementing transactional outbox patterns
- Secrets Management
- Replacing the current secrets pipeline (AWS Secrets → Terraform → K8s Secret) with a more flexible solution like External Secrets Operator
- File Handling & S3 Uploads
- Refactoring image upload pipeline to use UUIDs instead of auto-increment IDs
- Enabling direct uploads to S3 using presigned URLs
- Scalability & Infrastructure
- Revamping Kubernetes resource limits/requests
- Implementing autoscaling using Karpenter and KEDA
- Leveraging spot instances for cost optimization
- Testing & CI/CD Enhancements
- Integrating Cypress tests into the CI pipeline
- Finalizing per-PR deployment isolation:
- Separate instances of MailDev
- Isolated Manticore index clusters
- Kafka topic cleanup automation
- Implementing simple A/B testing across backend and frontend
- Setting up alerts and dashboards for everything—we need to know about infrastructure issues before they happen, or at least before customer support does.
- Defining blueprints so that regular developers can easily set up monitoring for their features.
- DevOps Tech Stack:
- Kubernetes, AWS.
- Terraform, ArgoCD, GitHub Actions, Prometheus, Loki, Manticore Search, Redis, Kafka, Keda, Aurora, MySQL.
How we work:
- The Platform team currently consists of about 3.5 people, including CTO David Gazdoš.
- There are 23 developers overall.
- We have daily stand-ups, weekly Backend Tech Meetings and Frontend Tech Meetings, and bi-weekly deep dives into new features.
- We work out of offices near Kolbenova metro station, and the occasional Domů office is possible.
What we offer:
- Work with awesome people like the internal systems guru Simon, and CTO David.
- Listen to a podcast with David (CTO) & Simon to get an even better understanding of how our development team works and what we’re currently tackling.
- We build everything in-house, so there’s a wide variety of problems to solve—you won’t get bored, and there’s always something to work on and innovate.
- You’ll see the results of your work immediately—when we rework or optimize a process, it typically has visible positive effects, not just on the website but also in the warehouse, shipping, customer support, or intake. If something goes wrong, you'll hear about it within minutes!
- An amazing opportunity to have a significant impact on the future of Knihobot and to grow with us exponentially.
- MultiSport card, employee discounts on buying and selling books, and discounts with partners.
- Professional development budget.
- One extra week of vacation after one year of cooperation, two extra weeks after two years.
- Option to gain ESOP (employee stock ownership plan) and have a financial stake in the Firma’s success.
- An informal environment and a pragmatic approach to getting things done.
