Job description
We are looking for a Team Lead / Architect to drive design and delivery of large-scale smart metering and utility platforms (HES, MDM, WFM, GIS, SSO) deployed across multiple enterprise client engagements, operating at production scales of 3.8M+ meters with 10M+ in planning. This role owns technical architecture, design documentation, and mentors a team of engineers delivering high-throughput, high-availability systems.
Key Responsibilities
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 Pg. Bouncer). 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.
Required Skills
& Experience: 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 (Pg. Bouncer), 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/Lo.
RaWAN 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
Good to Have 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/Open. Bao).
