– Senior Software Engineer (Microservices & IoT Platform – On-Prem) Location

Purpose of the Role

We are looking for a Senior Software Engineer to design and develop robust microservices for an onpremise IoT platform. The role involves building services that handle device communication (MQTT), high-volume data processing, and integration with BOS systems, while ensuring reliability, performance, and deployability across customer environments with limited infrastructure. The ideal candidate should be hands-on, strong in backend development, and comfortable working in distributed systems running outside cloud-managed environments.

Key Responsibilities

1. Microservices Development

- Design and develop lightweight, high-performance microservices
- Implement REST/gRPC APIs for BOS and external integrations
- Ensure clean separation of concerns and modular design
- Build services that are environment-agnostic and easily deployable

2. IoT & MQTT Integration
- Develop services to

- consume MQTT messages from devices
- process and validate incoming data

- Implement:

- message parsing
- retry mechanisms
- fault tolerance
- Handle:

- intermittent connectivity
- duplicate messages and out-of-order events

3. Data Processing & Storage
- Handle high-volume IoT data ingestion
- Design efficient data handling logic for:

- real-time processing
- batch processing (if required)
- Work with PostgreSQL for:

data persistence optimized queries
- Ensure productive disk and memory usage in constrained environments

4. Distributed System Implementation
- Implement:

- asynchronous communication
- event-driven patterns





- Handle:

- concurrency
- idempotency
- eventual consistency
- Work with self-hosted messaging systems (MQTT brokers, Kafka, RabbitMQ, etc.)

5. Performance, Reliability & Scalability
- Optimize services for:

- high throughput
- low latency

- Identify and fix performance bottlenecks
- Ensure services scale within fixed hardware limits (not infinite cloud scaling)
- Build resilient services with:

- retry strategies
- circuit breakers (if applicable)

6. Deployment Awareness & Operability
- Write services that are:

- container-friendly (Docker)
- easy to configure via environment/config files
- Understand:

service startup dependencies configuration management
- Support:
- on-prem deployments and upgrades
- Ensure services are:
- easy to debug in real environments (logs, error handling)

7. Code Quality & Best Practices
- Follow coding standards defined by architects
- Write clean, maintainable, testable code
- Participate in:

code reviews design discussions
- Collaboration •

Work closely with

- System Architect (for design clarity)
- DevOps (for deployment & release packaging)
- QA team (for testing and validation)
- Contribute to improving overall system design

9. Production Support




- Troubleshoot production issues in customer/on-prem environments
- Perform root cause analysis
- Fix bugs and improve system reliability
- Handle real-world issues like config mismatches, infra limitations

Required Skills & Experience Experience
- 5–8 years in backend development
- Strong experience in microservices architecture
- Experience working on production-grade systems

Technical Skills
- Strong programming skills in:
- C / Go
- Experience with:

- REST APIs
- distributed systems

- Robust understanding of:

- multithreading
- concurrency

IoT & Messaging
- Experience with:

- MQTT (preferred / important)
- message queues / event systems
- Understanding of real-time data processing

Database
- Strong knowledge of PostgreSQL
- Experience in:

- query optimization
- indexing
- handling large datasets

Infrastructure & Deployment Awareness
- Experience with:
- Docker (important)
- Basic understanding of:

- Linux systems
- networking basics (ports, connectivity)
- Exposure to:

- Kubernetes / K3s (positive to have)
- deployment environments (non-cloud setups preferred)

Good to Have
- Experience working on on-prem or edge-based systems
- Exposure to self-hosted messaging systems (Kafka, RabbitMQ, EMQX, Mosquitto)
- Knowledge of event-driven architecture
- Exposure to hybrid systems (on-prem cloud sync)

Soft Skills
- Strong problem-solving skills
- Ability to work independently with minimal supervision
- Good communication and collaboration skills
- Ownership mindset
