The Senior Staff Engineer combines the exemplary execution capabilities of a Staff Engineer with deep, authoritative domain ownership, acting as a technical pillar for the organisation by setting the vision for their area and cultivating deep expertise in others.

● Exemplary Project Execution: Perform all duties of a Staff Engineer, such as leading complex projects (both within and outside your domain), solving ambiguous problems, and ensuring high-quality delivery

● Cultivate Deep Expertise: Mentor other senior and staff-level engineers to build deep domain expertise, effectively acting as the "chief educator" for your systems and business logic

● Set the Technical Bar: Drive technical excellence and champion best practices within your domain, setting the standard for quality, performance, and operational readiness

● 10+ years of experience in software engineering, with a proven track record of becoming a recognised expert in a complex software domain

● Demonstrated experience in leading the architecture and rewrite of complex, business-critical systems

● Mastery of full-stack development in .NET (C#) and proficiency in modern front-end technologies (e.g., React)

● Deep, authoritative knowledge of event-driven architectures, microservices, and domain-driven design principles, and a history of applying them to solve major architectural challenges

● Exceptional and deep domain knowledge in a relevant business area

● Proven ability to mentor other senior engineers effectively and influence technical direction through expertise

● Strong understanding of database management (SQL Server/PostgreSQL) and cloud platforms (e.g., Azure, AWS)
