As a Senior Engineer, you serve as a specialist in the engineering team that supports the product. You help develop and gain insight in the application architecture. You can distill an abstract architecture into concrete design and influence the implementation. You show expertize in applying the appropriate software engineering patterns to build robust and scalable systems. You are an expert in programming and apply your skills in developing the product. You have the skills to design and implement the architecture on your own, but choose to influence your fellow engineers by proposing software designs, providing feedback on software designs and/or implementation. You show good problem solving skills and can help the team in triaging operational issues. You leverage your expertise in eliminating repeat occurrences.
Role Overview
We are looking for a Senior Software Engineer with 4–7 years of experience in software design and development, specializing in scalable backend systems.

- Ensure solutions are production-ready, with a strong focus on scalability, reliability, and performance
- Drive code quality, engineering standards, and infrastructure best practices across the team
- Provide technical leadership, including mentoring and fostering a strong learning culture
- Maintain deep ownership of production systems, including operational excellence and automation maturity
- Apply strong system design principles, including scalability, fault tolerance, and performance optimization
Observability & Reliability
- Ensure robust monitoring and observability practices are in place
- Leverage operational data to drive performance and stability improvements
- Promote a culture of observability aligned with organizational standards
Security
- Champion a security-first mindset across development
