C Developer
Job purpose
Seeking a seasoned Senior Technical Architect, preferably someone with Capital Markets/Financial Services experience, who can bridge legacy and modern engineering—refactor and extend systems in C while architecting .NET services for cloud-ready, scalable platforms. Proficient in defining architecture strategy, hands-on solutioning, programming, and partner with Cross functional teams and US stakeholders to deliver secure, resilient systems.
Key responsibilities
- Architecture Ownership: Define end-to-end solution architecture across apps, data, integration, and infrastructure; produce ADRs, HLD/LLD, NFRs, and security models.
- Legacy Modernization: Assess monolith/client-server systems and design migration paths using Strangler Fig, Anti-Corruption Layer, adapters/wrappers, façade and repository patterns; manage interop between COM/DCOM, .NET, and native components.
- Modern Patterns: Establish architectures with microservices, hexagonal (ports-and-adapters), DDD, CQRS, event-driven designs, and API-first principles.
- Integration Strategy: Design REST/gRPC APIs, messaging (Kafka/RabbitMQ), contract/versioning and backward compatibility; secure partner integrations and data flows.
- Reliability & Performance: Champion observability (metrics/logs/traces), capacity planning, performance tuning, caching, and resiliency (circuit breaker, bulkhead, retry/backoff).
- Security by Design: Drive threat modeling, secure coding standards, encryption in transit/at rest, identity/roles, secrets management, and vulnerability remediation.
- Cloud & DevOps Collaboration: Guide AWS/Azure solutioning; partner with DevOps on CI/CD, IaC (Terraform/Bicep), artifact lifecycle, release governance.
- Global Delivery: Coordinate with distributed teams across US/EMEA/APAC time zones; align architecture with delivery cadences and SLAs; ensure EST overlap.
- Stakeholder Management: Translate technical choices into business outcomes; present trade-offs/risks to senior leaders and clients.
Key competencies
- 12+ years in software engineering/architecture; 5+ years in architect/tech-lead roles with good coding skills.
- Strong hands-on with C and C# .NET.
- Demonstrated end-to-end legacy modernization to cloud-ready architectures (service decomposition, data refactoring, strangler/ACL approaches).
- Deep knowledge of architectural patterns (layered, SOA, microservices, hexagonal, DDD, CQRS, EDA) and NFRs (scalability, reliability, security, performance).
- Integration expertise: REST/gRPC, message brokers, schema/versioning strategies, and consistency models (transactional vs. eventual).
- Experience with AWS/Azure, containers/orchestration (Docker/Kubernetes), and DevOps (CI/CD, IaC, artifact management).
- Excellent communication and documentation skills; proven ability to lead design workshops and influence senior stakeholders.
- Track record working with global teams and delivering across distributed time zones.
- Working experience on Fixed Income securities trading domain and platforms, with real-time transactions KPIs is highly desirable.
Nice to Have
- Financial services domain exposure and familiarity with regulatory/security frameworks.
- Performance engineering (profiling native code, memory management), static/dynamic analysis, secure interop (P/Invoke, COM visibility).
