Senior Software Engineer (Cloud/Backend)

We are building a brand-new Platform group and are looking for a Lead Technical Anchor to act as a Key Technical Partner to the Principal Architect. You will be one of the main players in the group, driving the ideation, design, implementation, maintenance, and monitoring of a massive multi-tenant SaaS distributed ecosystem and inference platform. This mission-critical platform operates across three tiers: Cloud (Worldwide SaaS), On-Premise (Gateways / MSC2), and Edge Device Sensors (SDR / IoT tactical devices). You will work in close partnership with the Principal and Software Architect to translate high-level architectural vision into production reality, lead the design and implementation of highly complex distributed systems, and set engineering standards for the team.

Responsibilities

• Key Technical Partner: Work in close partnership with the Principal and Software Architect to translate high-level architectural vision into production reality.
• Architect Distributed Systems: Lead the design, planning, and implementation of highly complex, high-throughput distributed systems from the ground up, ensuring seamless data ingestion and inference across Edge, On-Prem, and Cloud layers.
• Lead by Example in Code: Write extremely sharp, scalable, and maintainable code. You will set the engineering standards for the rest of the team using Node.js, Express, and NestJS.
• End-to-End Ownership: Take full ownership of the software lifecycle—from architectural design and backend coding to automated deployment and production monitoring. Ensure 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.

Requirements

• Background: B.Sc. in Computer Science (from a leading university) OR Alumnus of an elite military technology unit.
• Experience Level: 7+ years of overall software engineering experience, with at least 5+ years of hardcore backend development focusing on distributed systems.
• Expert Coder: You are still deeply hands-on and "hot on code".
• Core Backend Stack: Expert-level knowledge of JavaScript (JS) and TypeScript (TS). Deep, authoritative expertise in Node.js, Express, and NestJS, alongside a profound understanding of the JS Event Loop and asynchronous programming.
• Distributed Systems: Proven, battle-tested experience planning, designing, and implementing complex, high-throughput distributed systems from scratch.
• Cloud Native: 5+ years across on of AWS, Azure, or GCP with a focus on managed services (Serverless, EKS/AKS/GKE, auto-scaling).
• Architecture: Proven experience with Event-Driven Design (one of Kafka, RabbitMQ, Redis Stream) and Microservices.
• State Management: High-speed in-memory state (Redis) and relational data stores (PostgreSQL).
• SaaS & Security: Expertise in secure, multi-tenant SaaS, ideally with knowledge of Zero Trust Architecture (ZTA) and mTLS.
• Containers: Hands-on experience with Docker and basic Kubernetes.
• Frontend Willingness: Practical experience with React and a strong willingness to touch client-side code when necessary to deliver end-to-end features.

Nice to have

• Infrastructure as Code: Deep expertise treating infrastructure as software using Server-less Framework, Terraform, AWS CDK.
• AI Tooling: Experience enriching and optimizing development using dev-assisting GenAI tools (such as Cursor, CoPilot, or ClaudeCode).
• Data Scale: Experience with time-series telemetry pipelines and long-term storage tiering.
• Observability: Experience implementing observability stacks (Prometheus, Grafana, ELK, Datadog).
• Additional Tech: Python 3.6+ experience and multi-process/threaded application knowledge.
