About the Role

As a Networking Engineer with Security in Cloud Engineering, you will help build secure, scalable, and resilient AWS networking environments that support business growth. This role offers the chance to influence architecture, strengthen cloud security, and enhance infrastructure reliability while collaborating across teams and expanding your expertise in advanced networking, infrastructure-as-code, and security best practices.

What You Will Do

• Design, implement, and maintain high-performance, scalable and secure RESTful APIs and services using .NET Core / .NET 6+ hosted in Azure.
• Collaborate with front-end engineers to define, design, and deliver new features.
• Work closely with QA engineers to ensure software is thoroughly tested before production release.
• Integrate third-party services and APIs as required.
• Participate in code reviews, architecture discussions, and continuous improvement initiatives.
• Model and enforce data access patterns.
• Write efficient T‑SQL and leverage Dapper for data access (no heavy ORMs/EF).
• Apply caching (Azure Cache for Redis), partitioning/sharding, and idempotent/event-driven processing (Azure Service Bus/Event Hubs).
• Profile and optimize hot paths (dotnet-counters/trace, PerfView, BenchmarkDotNet).
• Deliver observable services (OpenTelemetry traces/metrics/logs, Azure Application Insights) with actionable SLO/SLA signals.
• Collaborate on architecture, trade-offs, and failure modes.
• Participate in code reviews and mentor peers (incl. AI-assisted workflows).
• Uphold security best practices (OWASP API, Azure Key Vault, least privilege, rate limiting).

MUST HAVE

• 5+ years of experience with .NET Core backend engineering focused on API development.
• Hands‑on experience with Microsoft Azure services (Azure SQL, Blob Storage, Cosmos DB, Redis, etc.).
• Strong understanding of relational databases and T‑SQL fundamentals.
• Experience with Dapper or equivalent micro‑ORMs.
• Proven experience building/operating systems with high throughput, distributed components, and internet‑scale considerations.
• Proficiency with AI‑assisted development (e.g., Copilot/ChatGPT).
• Practical observability (logs/metrics/traces) and performance optimization.
• Clear and concise communication.
• Comfortable in highly transparent cultures.
• Upper‑Intermediate English level.

NICE TO HAVE

• Familiarity with Azure SQL Hyperscale, Cosmos DB modeling, and Redis patterns.
• Understanding of event‑driven design and idempotent processing.
• Exposure to observability stacks (metrics/tracing/logging).
• Basic container literacy (Docker/Kubernetes familiarity), though infra is handled by a dedicated team.
• Experience mentoring engineers or coordinating contributions across a small pod.
• Experience in gaming development and/or startup companies.

Perks & Benefits

• Professional growth: Accelerate your professional journey with mentorship, TechTalks, and personalized growth roadmaps.
• Competitive compensation: We match your ever‑growing skills, talent, and contributions with competitive USD‑based compensation and budgets for education, fitness, and team activities.
• A selection of exciting projects: Join projects with modern solutions development and top‑tier clients that include Fortune 500 enterprises and leading product brands.
• Flextime: Tailor your schedule for an optimal work‑life balance, by having the options of working from home and going to the office – whatever makes you the happiest and most productive.
