Integration Software Engineer

ABOUT US Harmattan AI is a next-generation defense prime building autonomous and scalable defense systems. Following the close of a $200M Series B, valuing the company at $1.4 billion, we are expanding our teams and capabilities to deliver mission-critical systems to allied forces. Our work is guided by clear values: building technologies with real-world impact, pursuing excellence in everything we do, setting ambitious goals, and taking on the hardest technical challenges. We operate in a demanding environment where rigor, ownership, and execution are expected. ABOUT THE ROLE We are seeking a hands-on, product-side Integration Software Engineer to join our Software Engineering team. In this role, your core mission is to develop, validate, harden, and fold software interfaces into our core product line, enabling our advanced systems to connect seamlessly with third-party and customer-provided data streams. This is a role for a focused, skilled coder who builds robust connectors rather than a systems-engineering generalist. You will own a multi-data-stream scope built to extend from one integration family to others over time, operating with a reusable-capability mindset so that each new integration is faster and more reliable than the last. Note: This position is primarily office-based, requiring episodic travel to customer operational sites for integration validation and commissioning phases rather than a permanent forward-deployed site presence. RESPONSIBILITIES - Interface Analysis: Rigorously study third-party data interfaces and explicitly define how external data feeds will robustly flow into our software architecture. - Connector Development: Design, code, and deploy the critical software interfaces and backend connectors required to ingest and translate raw external data into our system's expected internal format. - Data Handling: Manage complex data ingestion architectures with absolute stability—ensuring high performance across data formatting, framing, coordinate frame transformations, precise timing/latency, and resilient error handling. - Validation & Testing: Test integrations end-to-end against highly representative data simulators, and travel to field sites to verify real-world correctness, latency bounds, and operational reliability. - Hardening & Productization: Harden all developed integrations, folding durable and reusable software capabilities directly back into the core product baseline to avoid per-deployment one-offs. - Regression Protection: Continuously support and build automated regression testing workflows for external integrations to guarantee that new core product releases never break active deployed connections. - Collaboration & Roadmap Feedback: Partner closely with integration engineering, product, and field deployment teams to surface critical integration requirements and drive them directly into the core product roadmap. CANDIDATE REQUIREMENTS - Educational Background: A strong academic record—ideally in a technical field (e.g., Computer Science, Engineering, or a highly quantitative discipline). - Software Engineering Background: Deep, practical experience in software engineering (experience with C++ or Rust are a plus), specifically focused on systems integration, backend data-interface engineering, and connector development. This role requires an active coder. - Data Interface Expertise: Demonstrated experience working with structured data feeds, framing/parsing algorithms, real-time streaming, or embedded data-exchange protocols. - Systems Thinking & Complex Projects: An avid learner with a demonstrated capacity to handle large-scale, complex systems spanning multiple subsystems, third-party systems, and external hardware-adjacent interfaces. - Linux & Operations: Highly comfortable operating in Linux environments; proficient at deploying, configuring, and debugging software stacks within demanding, operational settings. - Adaptability, Mobility & Field-Willingness: Thrives under pressure in a fast-paced, dynamic environment; embraces a "no-task-is-too-small" mentality. Must be fully willing and able to conduct episodic travel for on-site validation and work hand-in-hand with customer technical teams. - Communication & Influence: Excellent written and verbal communication skills, capable of leading and influencing diverse stakeholders—from junior engineering members to senior customer executives. - Languages: Professional working proficiency in written and spoken English. Additional regional languages are considered a strong asset. - Commitment: 100% dedication to Harmattan AI’s mission, vision, and ambitious growth plans, ready to go the extra mile to ensure operational excellence and fulfill confidentiality and clearance/vetting obligations. NICE-TO-HAVE - Direct experience integrating third-party data streams or hardware-adjacent devices. - Familiarity with industry interoperability and specialised data-exchange standards. - Prior domain background in large-scale technology or aerospace industries. - Prior experience working within vetted, highly confidential software environments. We look forward to hearing how you can help shape the future of autonomous defense systems at Harmattan AI.
