About the Role

Join a world leader in cloud-based software solutions for the space design industry. As a Principal Software Engineer, you will work on the Flex Platform, a cloud platform with business and core components connecting Cyncly applications and products, including modular web applications, micro frontends, microservices, SQL/NoSQL databases, Azure Blob Storage, and Azure Cloud services. This is aligned with the existing Flex Platform context described for the Senior Software Engineer, Team Lead, and Technical Manager roles.

In this role, you will act as a technical reference for complex solutions, helping teams design scalable, secure, high-quality, and cost-effective systems. You will guide technical decisions, mentor engineers, collaborate with Team Leads and Technical Managers, and help ensure that architecture, engineering practices, automation, and delivery standards are consistently applied across the platform. This builds on the responsibilities already present in the Senior Software Engineer, Team Lead, Technical Manager, QA Automation, and Senior DevOps roles, including mentoring, architecture collaboration, code quality, automation, security standards, DevOps practices, and cross-functional technical leadership.

This position is ideal for someone with deep hands-on engineering experience who can influence technical direction, solve critical problems, raise engineering standards, and support teams in delivering world-class SaaS products in an agile environment. The existing roles emphasize high-quality delivery, Agile ways of working, technical documentation, mentoring, troubleshooting, and collaboration across disciplines.

Responsibility:

Define, guide, and review technical solutions for complex platform capabilities, ensuring they are scalable, secure, maintainable, performance-oriented, and cost-effective. Existing software engineering roles already emphasize performance-oriented code, high availability, security standards, and robust solution design.

Act as a technical authority for the Flex Platform, supporting engineers, Team Leads, Technical Managers, QA, DevOps, and architects in making long-term technical decisions. This reflects the existing expectation that senior roles collaborate with architects, serve as technical references, and guide team members on best practices.

Lead the design and evolution of software architecture patterns, including microservices, event-driven architecture, CQRS, BFF, API design, frontend architecture, and cloud-native patterns. These architecture topics are already listed as required knowledge for Senior Software Engineer, Team Lead, and Technical Manager roles.
