The following questions reflect patterns observed in our hiring process. While specific inquiries will vary depending on your team and interviewer, these categories represent the core areas we assess. Use these to gauge your readiness and practice articulating your technical decision-making process.

Technical Domain and Tooling

These questions assess your practical experience with the technologies we use and your ability to manage infrastructure. We look for depth in your understanding of CI/CD pipelines and library management.

• How have you managed library updates and dependency management in your previous roles?
• Can you describe your experience with Kotlin and CDK in a cloud-native environment?

Preparation at MOIA should focus on demonstrating both technical competence and a proactive, collaborative mindset. You should be prepared to discuss not just how you code, but why you choose specific architectural paths.

Technical Depth – We evaluate your hands-on experience with our core stack, including Kotlin and AWS. You should be ready to explain the trade-offs of your past technical decisions and demonstrate a clear understanding of cloud-native development.

Problem-Solving Structure – We look for engineers who can break down complex, ambiguous problems into manageable components. During technical discussions, prioritize clear communication of your thought process over finding a "perfect" answer immediately.

Collaboration and Communication – As a Backend Engineer, you will work closely with cross-functional teams. We assess how you explain technical concepts to non-technical stakeholders and how you handle feedback during collaborative sessions.

The MOIA interview process is designed to be rigorous but efficient. It typically begins with a high-level introduction to gauge alignment on culture and expectations, followed by technical assessments that test your ability to handle our specific infrastructure. We value transparency and directness, and we aim to provide a clear view of the team’s mission during these initial conversations.

Candidates should expect a process that emphasizes practical, real-world application over theoretical trivia. You will likely engage with both individual contributors and engineering leadership. We look for candidates who are not only technically proficient but also genuinely invested in the mission of sustainable urban mobility.

This visual timeline illustrates the typical progression from initial screening to final assessment. Use this to pace your preparation, ensuring you are ready for both high-level behavioral discussions and deep-dive technical reviews. Be aware that scheduling may vary, so remain flexible and communicate your availability clearly from the start.

Technical Proficiency and Infrastructure

We prioritize engineers who are comfortable with the full lifecycle of a service. You will be evaluated on your ability to write clean, maintainable code and your familiarity with cloud infrastructure.

Be ready to go over:

• Cloud-native architecture – Specifically your experience with AWS services and serverless patterns.
• CI/CD pipeline management – How you automate deployments and maintain environment stability.

As a Backend Engineer, your primary responsibility is to build and maintain the systems that power MOIA’s fleet. You will spend a significant portion of your time writing high-quality Kotlin code, managing AWS infrastructure, and ensuring that our services are performant and secure.

You will collaborate daily with product managers, data scientists, and operations teams to translate business requirements into technical solutions. This involves participating in sprint planning, conducting code reviews, and contributing to the long-term technical roadmap. You are expected to be an active participant in improving our engineering culture and processes.

We look for engineers who bring a blend of technical expertise and a pragmatic approach to problem-solving.

• Must-have skills:
  • Professional experience with Kotlin or similar JVM-based languages.
  • Strong proficiency with AWS cloud infrastructure.
  • Demonstrated experience in a microservices environment.
• Nice-to-have skills:
  • Experience with vehicle-to-cloud communication or IoT systems.
  • Background in autonomous vehicle perception or mission-critical systems.
• Soft skills:
  • Strong verbal and written communication.
  • Ability to thrive in a fast-paced, sometimes ambiguous environment.

Q: How long does the interview process typically take? The timeline can vary, but we strive to move candidates through the process efficiently. Expect a few weeks from the initial screen to a final decision.

Q: What is the best way to stand out during the interview? Candidates who demonstrate a deep understanding of our specific technical challenges and show genuine interest in the mobility sector tend to be the most successful. Be prepared to ask insightful questions about our architecture and mission.

Q: Is the work fully remote? MOIA typically operates with a hybrid model. Please confirm the specific expectations for your role and location during your initial recruiter call.

• Be prepared for technical depth: Don't shy away from explaining the complexity of your past projects. We want to see that you understand the "under the hood" mechanics of your work.
• Clarify expectations: If you are unsure about a question or a task, ask for clarification. We value candidates who seek to understand the problem before jumping to a solution.
• Focus on the impact: When discussing your past experience, emphasize the impact your work had on the business or the user.
