We are actively seeking a highly skilled Senior Software Engineer to join our dynamic team. This role is pivotal for a professional who specializes in designing and building scalable, cloud-native, multi-tenant SaaS infrastructure and backend systems.

Your primary responsibility will be to architect and develop robust backend services, high-throughput data pipelines, and scalable microservices. While your core focus will be on the backend and cloud infrastructure, you will take ownership of the full feature lifecycle—which includes a strong willingness to develop and maintain clear, efficient client-side interfaces to deliver complete end-to-end solutions.

Responsibilities:

End-to-End Ownership: You will take full ownership of the software lifecycle—from architectural design and backend coding to automated deployment and production monitoring. You will champion a 'You Build It, You Run It' culture, ensuring the high availability and observability of our multi-tenant SaaS environment.

Backend & Infrastructure Focus: Design and implement high-performance backend tasks, robust infrastructure, and high-throughput Backend-for-Frontend (BFF) layers utilizing both REST and gRPC protocols to process real-time sensor data and telemetry.

Full-Stack Delivery: Seamlessly transition to front-end development (React) when required, ensuring the backend infrastructure connects smoothly to a streamlined and user-friendly web client.

Automation & CI/CD: Drive feature delivery using Agile methodologies, replacing manual handovers with automated CI/CD pipelines that ensure seamless integration and validation from development to production.

Requirements:

B.Sc. in Computer Science from a leading university OR Alumnus of an elite military technology unit - MUST

At least 5 years of hands-on backend software development experience, primarily in Node.js – A MUST

Deep knowledge of the JS event loop and asynchronous programming. – A MUST

Practical experience with frontend development (e.g., React) and a strong willingness to contribute to client-side development when necessary to deliver end-to-end features – A MUST

At least 5 years with Cloud Computing across at least one of the big three providers (AWS, Azure, GCP), with a focus on Cloud-Native services. This includes expertise in serverless computing, managed container orchestration (EKS/AKS/GKE), and auto-scaling strategies beyond basic IaaS/VM management – A MUST

Proven experience designing scalable services using Microservices Architecture and related patterns (e.g., Service Mesh, API Gateway, BFF).

Strong understanding of Event-Driven Design (e.g., high-throughput message brokers like Kafka, RabbitMQ, SQS) and Domain Driven Design (DDD) principles.

Experience with high-speed in-memory state management (e.g., Redis) and relational data stores (e.g., PostgreSQL).

Hands-on experience with containerization technologies, specifically Docker and basic Kubernetes usage.

Deep understanding of Infrastructure as Code (IaC) principles. Proven experience managing cloud infrastructure programmatically using tools like Terraform, AWS CDK, or Pulumi (we treat infrastructure as software) – A Big Advantage

Deep expertise in designing highly secure, multi-tenant SaaS solutions, ideally with knowledge of Zero Trust Architecture (ZTA), mTLS, and secure edge-to-cloud communications.

Strong understanding of CI/CD concepts and automation tools.

Team player, with strong communication, collaboration, and active listening.

Agile/Scrum environment expertise.

Experience designing data pipelines for high-volume time-series telemetry and implementing long-term, cost-optimized data retention strategies (e.g., Object storage tiering).

Experience with Geospatial processing (GIS), mapping technologies (Map tile services, GeoJSON, OGC standards), and implementing spatial rules/geo-fencing.

Advanced Kubernetes experience (Operators, CRDs, Helm) for complex deployment scenarios.

Experience implementing Observability stacks (Prometheus, Grafana, ELK, Datadog).

Python 3.6 and above experience.

Multi-process/threaded application knowledge.

Extensive startup experience.

Knowledge of Networking and Operating Systems (Linux) fundamentals.
