Preparation for Tagup should be balanced between deep technical mastery and clear, structured communication. Because the team values engineers who understand the "why" behind their code, you must be prepared to defend your design choices during every stage.

Role-related Knowledge – You must be fluent in Python and SQL. Interviewers will look for evidence that you can write clean, production-ready code that is easy for others to maintain and audit.

Problem-solving Ability – You will often face open-ended technical scenarios. Focus on demonstrating a systematic approach: clarify requirements, identify constraints, propose multiple solutions, and explain your rationale for selecting the final path.

Communication and Collaboration – You will be working in a fast-moving, collaborative environment. Be prepared to share your knowledge, accept feedback, and clearly articulate the trade-offs of your technical decisions to both engineers and leadership.

Alignment with Mission – Tagup is a mission-driven company. You should be able to articulate why you are passionate about the intersection of AI and industrial logistics, and how your personal values align with their focus on safety and reliability.

The interview process at Tagup typically follows a structured path, though the pace can vary depending on the team's immediate needs. Most candidates begin with an initial screening call, followed by a technical deep dive with a team lead or the CTO. You should expect a practical take-home assignment or a live coding challenge that tests your ability to build and deploy functional services.

The process is designed to be rigorous but practical. They prioritize candidates who can demonstrate hands-on experience, often using real-world projects or specific technical exercises that mirror the actual work you would do at the company. Be prepared for a high-intensity environment where the team moves quickly to assess talent.

This timeline illustrates the progression from initial screening through technical assessment to leadership interviews. Use this to pace your study; ensure you are comfortable with your Python and SQL fundamentals before the technical screening, and set aside dedicated time for the take-home assessment, which can be time-intensive.

Technical Implementation

This area focuses on your ability to translate requirements into working code. Expect to be evaluated on your mastery of Python and your ability to write efficient, readable SQL.

Be ready to go over:

• REST API development – Best practices for versioning, authentication, and error handling.
• Data modeling – How you structure databases for performance and long-term maintainability.
• Testing strategies – Your approach to integration and unit testing to ensure high reliability.

Example scenarios:

• "Build a service that connects to a data store and exposes specific endpoints."
• "Refactor this snippet of code to improve readability and performance."

System Architecture

As a Software Engineer, you will be expected to think about the "big picture." This includes how your services fit into the broader Tagup ecosystem.

Be ready to go over:

• Cloud infrastructure – Experience with AWS and Terraform is a significant differentiator.
• Containerization – How you utilize Kubernetes to orchestrate services.
• Networking – Understanding basic computer networking concepts to troubleshoot service communication.

Example scenarios:

• "How would you handle a sudden spike in data ingestion in our pipeline?"
• "Compare the pros and cons of using a microservices architecture versus a monolithic approach for this specific problem."

Your day-to-day as a Software Engineer at Tagup will be highly varied. You will spend a significant portion of your time building and maintaining core services, including the APIs that power their customer-facing platforms. You will write high-performance SQL queries to ensure that data retrieval is fast and accurate, which is critical for the AI models that control industrial equipment.

Collaboration is central to the role. You will work closely with data scientists to build the data pipelines that feed their models, ensuring that the input data is clean, consistent, and reliable. You will also participate in code reviews and architectural planning sessions, contributing to the team's collective knowledge and helping to refine the company's technical standards.

A strong candidate for Tagup is someone who is not just a coder, but a systems-thinker. You should have a solid foundation in software engineering principles and a desire to work in a high-stakes, mission-driven environment.

Must-have skills:

• Fluency in Python and SQL.
• Proven experience in building and deploying REST APIs.
• Proficiency with Kubernetes and container orchestration.
• Ability to write clean, well-tested, and maintainable code.

Nice-to-have skills:

• Experience with AWS and Terraform for infrastructure as code.
• Knowledge of robust integration testing frameworks.
• Understanding of computer networking fundamentals.

Q: How long does the interview process typically take? A: While it varies, candidates have reported processes ranging from a few weeks to a month. It is a multi-round process involving technical assessments and interviews with leadership.

Q: What is the best way to prepare for the take-home assignment? A: Treat the take-home assignment as a production task. Focus on clean code, robust error handling, and clear documentation. Ensure your deployment instructions are easy to follow, as this reflects your real-world engineering habits.

Q: Is there a specific focus on defense or security? A: Yes, because Tagup works with defense and aviation sectors, you should be prepared for questions regarding your background, citizenship, and your ability to work on sensitive projects.

Q: How can I stand out as a candidate? A: Demonstrate a deep curiosity about the company's domain. Being able to connect your technical skills to the mission of making industrial systems safer and more reliable will set you apart.

• Own your design decisions: When asked about a technical choice, explain the trade-offs you considered. Showing that you understand the "why" is more important than choosing the "perfect" tool.
• Be proactive in communication: Given the fast-paced nature of the company, don't be afraid to follow up if you have questions or if the process feels stalled.
• Prepare for the CEO/CTO round: These interviews are as much about culture and mission alignment as they are about technical skill. Be ready to discuss your long-term career goals and why you want to work at Tagup specifically.
• Emphasize your experience with scale: If you have worked with high-throughput systems or large datasets, highlight these experiences, as they are central to Tagup's mission.

The Software Engineer role at Tagup is a unique opportunity to apply your technical skills to mission-critical systems that have a real-world impact.
