Requirements

What you’ll need

B.Sc. in Computer Science, Engineering, or related technical field; M.Sc. a plus but not required
4+ years of experience as a software engineer , ideally in high-volume or distributed systems environments
Strong programming skills in Python, Java, Scala, or another systems-focused language
Experience with data integration and ingestion pipelines —you understand what it means to bring data in from source systems, transform it, and deliver it reliably downstream.
Solid grasp of engineering fundamentals , including version control, modular design, testing, and performance tuning
Proficiency in using AI coding assistants (e.g., GitHub Copilot, Cursor, or Claude Dev) to accelerate the Software Development Life Cycle (SDLC), including automated unit test generation, refactoring, and documentation
Deep understanding of specification-driven development
Ability to author and maintain rigorous technical specifications (using OpenAPI, AsyncAPI, or Protocol Buffers) that serve as the "source of truth" before implementation begins
Ability to craft complex, context-rich prompts to solve architectural problems, debug legacy systems, and translate business requirements into technical scaffolds
Familiarity with concepts like schema evolution, event-driven architectures, observability, and role-based access control
A collaborative mindset —comfortable working across domains, products, and infrastructure layers
A strong sense of ownership and accountability —you care deeply about building systems that last.
