Job Description
ETPL is 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 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.
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 (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
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/OpenBao).
