Senior Backend Engineer Job Description
We’re looking for a Senior Backend Engineer
who is thoughtful about design, passionate about delivering value incrementally, and committed to building systems that are simple to understand, easy to change, and resilient in production.
About the team:
Our Backoffice product is a role-based fleet management system. It offers insights to our users on mobile app usage, tour performance, map-supported real-time delivery progress, detailed usage analytics, and many other relevant business KPIs. It also supports Bettermile in maintaining important data, such as depot details and customer-specific configurations, which are essential for scaling up the business quickly and easily.
You will be taking care of:
- Driving the future vision and direction of our engineering solutions.
- Designing and implementing features and improvements across all levels of our infrastructure and backend systems.
- Proactively collaborating with other teams, Product Owners, On-Call Engineers, and stakeholders.
- Demonstrating strong ownership during the planning phase, in collaboration with Product Owners.
- Contributing to strategic, long-term team decisions—such as framework and architecture choices—guided by business needs.
- Supporting ongoing efforts to optimize our existing microservice architecture.
- Actively giving and receiving feedback to foster continuous improvement.
- Mentoring and supporting the development of team members.
You check these boxes:
- You bring a strong foundation in software engineering: You’ve worked hands-on across multiple complex systems and teams, gaining the perspective to recognize what’s universal and what depends on context
- You are proficient in a JVM language and have basic knowledge of Kotlin, along with its ecosystem, including build tools, IDEs, common libraries, and frameworks.
- You automate the delivery process: You know how to use Infrastructure as Code, build tools like Gradle, and deployment pipelines to efficiently build, test, and deploy software.
- You optimize for feedback: You value fast, high-quality feedback—both from tests and from people. You write testable code and test early and often, ideally by practicing Test-Driven Development (TDD).
- You think in patterns, not just tools: You understand the core principles behind messaging, persistence, and distributed systems, and you navigate trade-offs with clarity. You choose the right approach for the context—not because it’s trendy or familiar, but because it fits the problem.
- You design incrementally: You know how to break complex problems into thin slices of value. You work in small steps, writing modular, cohesive, and loosely coupled code, and you continuously refactor to keep the design simple, clear, and adaptable.
- You prefer to build software with others: You work closely with engineers and domain experts to co-create solutions. You thrive in a collaborative, cross-functional team where ideas are shared early and continuously and decisions are made together—not handed down an assembly line.
- You optimize for learning: You see Continuous Delivery as a way to learn quickly about the problem and the solution. You actively build your own skills and understanding—and you help others grow by mentoring, sharing knowledge, and working openly.
- You communicate clearly: You’re fluent in Business English, and capable of communicating effectively not just through code, tests and version control, but also verbally across teams and roles.
It is awesome if you also have:
- Familiarity with performance, load, or stress testing, and an interest in ensuring systems remain reliable under pressure.
- Exposure to data pipelines and orchestration tools like DBT or Airflow, supporting data-driven product development and operations.
