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.
- Provide technical mentorship and coaching to Senior, Mid-Level, Junior, and Intern engineers, helping improve code quality, design thinking, debugging, testing, and engineering practices. Existing roles already include mentoring interns, junior, mid-level developers, freshers, and other programmers.
- Review critical designs, pull requests, and implementation approaches to ensure clean code, quality, performance, maintainability, and compliance with company-defined security standards. The Team Lead role explicitly includes pull request reviews for clean code, quality, performance, cost-effectiveness, and security standards.
- Partner with Product, QA, DevOps, Security, and Cloud Operations to ensure features are delivered with strong quality, automation, observability, CI/CD readiness, and secure-by-default practices. The QA Automation role includes collaboration with Product/Testers and automation maintenance, while the Senior DevOps role includes collaboration with security and cloud operations teams and secure-by-default patterns.
- Drive engineering consistency across teams by promoting standards for APIs, micro frontends, automated testing, CI/CD, branching, documentation, and SDLC practices. Existing roles require knowledge of SDLC, automation tests, technical documentation, CI/CD, SCM practices, and Azure DevOps.
- Support troubleshooting and resolution of complex production or platform issues, helping teams identify root causes and implement sustainable fixes. Senior Software Engineer, Team Lead, and Technical Manager roles all include troubleshooting and debugging for faster defect fixing.
- Contribute hands-on to high-impact development tasks when needed, especially in areas requiring advanced technical expertise or cross-team alignment. Existing technical and senior roles are expected to develop code, design interfaces, build high-availability systems, and deliver with quality.
- Communicate technical concepts clearly to different audiences, including engineers, Team Leads, Technical Managers, Product stakeholders, and leadership. The Technical Manager role explicitly includes communicating technical concepts to the team, and several roles require strong communication skills in English.
