Senior Lead Engineer - .NET Core

• Own end-to-end solution architecture for utility/AMI platform modules, from design through
  production deployment.
  
• Author formal design documents, API reference documents, and ARB submissions for client and
  internal stakeholders.
  
• Design and review microservices architecture, ensuring scalability, fault tolerance, and clean domain
  boundaries.
  
• Apply appropriate design patterns to solve high-throughput, high-availability problems at billion-row
  data scale.
  
• Lead database architecture decisions for PostgreSQL at scale (partitioning, HA via Patroni,
  connection pooling via PgBouncer).
  
• Drive messaging architecture using RabbitMQ and Kafka for event-driven and high-volume telemetry
  pipelines.
  
• Architect and tune Elasticsearch for search, logging, or analytics use cases as required.
  
• Define and review Azure cloud architecture and deployment strategy (App Services, AKS, DevOps
  pipelines, networking).
  
• Lead containerization and deployment strategy using Docker on Ubuntu, including zero-downtime.
  (blue-green) deployments.
  
• Conduct code reviews, set engineering standards, and mentor a team of developers.
  
• Own security architecture review, including remediation of VAPT findings (RBAC, authentication,
  encryption).
  
• Collaborate with client technical and executive stakeholders, translating requirements into technical
  designs.
  
• Troubleshoot and resolve complex production issues across data pipelines, integrations, and
  infrastructure.
  

• 8+ years of overall software engineering experience, with demonstrated experience in technical
  leadership or architecture roles.
  
• Strong hands-on expertise in .NET Core (.NET 8 preferred) and modern C# development.
  
• Proven experience designing and implementing Microservices architecture.
  
• Strong working knowledge of Microsoft Azure (compute, storage, networking, DevOps/CI-CD).
  
• Hands-on experience with Elasticsearch for indexing, querying, and performance tuning.
  
• Deep expertise in PostgreSQL (16 preferred), including partitioning, replication/HA (Patroni),
  pooling (PgBouncer), and PostGIS for geospatial data.
  
• Practical experience with RabbitMQ and Kafka for asynchronous and event-driven messaging at
  scale.
  
• Strong grounding in software design patterns and ability to produce clear, implementable design
  documents.
  
• Experience with reverse proxy/load balancing (Nginx, HAProxy) and containerization (Docker) on
  Ubuntu/Linux.
  
• Familiarity with authentication/identity protocols (SSO, OAuth/OpenIddict, Entra ID) is a plus.
  
• Domain exposure to utility/AMI platforms — DLMS/COSEM meter protocols, HES/MDM systems,
  NB-IoT/LoRaWAN connectivity — is a strong plus.
  
• Excellent communication skills; ability to write precise, client-facing technical documentation and
  present architecture to both technical and executive audiences.
  

Requirements

• Experience with GIS-based systems (PostGIS, tile serving, geospatial APIs).
  
• Exposure to security hardening and VAPT remediation in production systems.
  
• Experience with multi-tenant SaaS architecture and key management (e.g., Vault/OpenBao).
