Description
We seek a system-level thinker and Senior Software Developer (5+ years) to design scalable, secure, and maintainable software that stands the test of time.
Are you passionate about crafting robust systems, improving engineering standards, and mentoring others? Do you know how to turn business needs into architecture and high-quality code—without over-engineering? We’re looking for someone who can partner across teams, make sound architectural decisions, and guide the team toward reliable, high-performance solutions.
This isn’t just about writing code. It’s about engineering systems, leading by example, and elevating quality across the stack. You’ll shape solutions end‑to‑end—designing APIs and data models, optimizing performance, and ensuring we build for long-term sustainability.
What you bring
·5+ years of hands‑on software development, operating at system level
·Deep understanding of SOLID, Clean Architecture, domain separation, dependency inversion, and GoF patterns
·Strong data design and performance tuning experience
·Proven experience with microservices and cloud design patterns
·Clear communicator who can translate business needs into technical designs and explain trade‑offs
What you’ll do
Scope & Impact
·Own end-to-end technical outcomes for services/systems
·Drive architectural decisions, system decomposition, and integration patterns
·Improve performance, reliability, security, and developer experience
·Anticipate risks, manage trade-offs, and reduce technical debt strategically
Core Technical Competencies
Advanced Application Development
·Architect and build complex systems in .NET (C#)
·Design scalable and secure REST APIs
·Implement advanced frontend architecture in Angular or React
·Optimize performance (async programming, concurrency handling, caching)
·Identify, prioritize, and eliminate technical debt Mindset: Think in terms of maintainability and long-term evolution.
Architecture & Design Mastery
·Apply SOLID (advanced), Clean Architecture, domain separation, and dependency inversion
·Expert application of GoF patterns
·Design for microservices and apply cloud‑native patterns (resilience, messaging, scalability)
Data Strategy
·Design relational database schemas (MS SQL, PostgreSQL)
·Optimise indexing, performance, transactions, and concurrency
·Implement polyglot persistence (including Cosmos DB for NoSQL) where appropriate
·Use Entity Framework efficiently and design file storage lifecycles (Azure Blob / AWS S3) Accountability: Performance and scalability at the data layer.
Cloud Architecture & DevOps
·Hands-on with Azure (App Services, Functions, Service Bus, Blob, Cosmos DB) and/or AWS (EC2, S3, RDS, Lambda)
·Design deployment strategies; define CI/CD pipelines (nice to have/lead when needed)
·Implement monitoring/observability and logging strategies
·Design scalable, cost-aware cloud infrastructure
Security & Performance Leadership
·Design authentication & authorization flows (OAuth2, OpenID Connect, JWT)
·Apply secure coding standards and anticipate vulnerabilities
·Optimize high‑load systems; implement effective caching strategies
Engineering Standards & Technical Leadership
·Lead code reviews and establish Git workflows
·Set logging, error handling, and operational standards
·Provide reliable estimations and delivery plans
·Mentor and coach junior/mid developers; lead technical discussions
·Protect architecture integrity and align solutions with strategic goals
Non-Technical Competencies
System Ownership
·Takes end-to-end responsibility for services/systems
·Anticipates risks and makes sound decisions under pressure
Mentoring & Leadership
·Coaches, pairs, and grows the team’s technical capabilities
·Facilitates design sessions and drives engineering improvements
Strategic Thinking
·Identifies technical debt and proposes pragmatic remediation
·Balances business priorities with long-term technical health
Communication
·Translates business requirements into clear technical designs
·Challenges ambiguity and communicates trade-offs and rationale clearly
Success Indicators (Examples)
·Systems meet SLOs for performance, reliability, and cost
·Clear architectural artefacts and standards adopted across the team
·Reduced incident frequency and faster MTTR through good observability
·Junior/mid engineers consistently level up through your mentorship
·Technical debt is visible, prioritized, and reduced with measurable impact
Signs You’re Ready for Next Level (Staff/Principal Track)
·You lead multi-system initiatives and cross-team architecture
·You drive platform strategy and organisation-wide standards
·You influence product strategy through technical vision and data
If you want to build systems that scale—and help others level up while you’re at it—we’d love to talk.
