• Drive and coordinate system migrations, integrations, and backend improvements across multiple teams.

• Manage technical dependencies while ensuring service continuity and minimal disruption.

• Ensure high standards of code quality, system reliability, performance, and maintainability.

• Evaluate implementations through testing, monitoring, and production feedback.

• Document technical solutions and share knowledge to support long-term system ownership.
  

Requirements:

• Extensive experience developing and operating backend services and APIs in production environments at scale.

• Strong proficiency in at least one backend programming language: Java, Scala, Go (Golang), or similar.

• Solid understanding of API design, schema evolution, and backward compatibility.

• Experience with data modelling, including versioning, auditability, and efficient querying.

• Familiarity with data pipelines and the differences between real-time and batch processing.

• Ability to navigate complex or unfamiliar codebases and quickly understand new technical domains.

• Experience working with system integrations, migrations, and distributed backend architectures.

• Strong analytical and problem-solving skills, with the ability to identify priorities and deliver solutions in ambiguous environments.
  

Personal Attributes

• Excellent communication and stakeholder management skills.

• Ability to build strong working relationships and collaborate across multiple engineering and business teams.

• Comfortable explaining complex technical concepts to different audiences.

• Proactive mindset with the ability to take ownership and drive initiatives independently.

• Strong sense of responsibility for the long-term impact, reliability, and quality of technical solutions.

• Adaptable and comfortable working in a dynamic environment with evolving priorities.

Additional Experience – Nice to Have

• Experience working in regulated, compliance-sensitive, or highly governed environments.

• Understanding of policy logic, enforcement processes, and regulatory reporting.

• Experience developing systems where data traceability, accuracy, and auditability are particularly important.

What We Offer:

• A dynamic and innovative workplace driving advancements in cutting-edge robotic technologies

• The opportunity to collaborate with talented cross-functional teams on meaningful and impactful projects

• Competitive compensation and comprehensive benefits package

• A supportive culture that fosters continuous learning, growth, and professional development
