• A collaborative, low-hierarchy team environment with direct exposure to technical leadership and customers

We are seeking a Mission Engineer to serve as the technical bridge between complex communications physics and our software orchestration layer.

Inspired by the SRE paradigm, Mission Engineering at Aalyria is a deeply hybrid role. You will combine the expertise of a Wireless Systems Engineer with the execution of a Software Integration Engineer. You will be responsible for ensuring that Spacetime’s system models are technically integrated, highly performant, and operationally resilient within live customer environments.

• System Modeling: Build and maintain high-fidelity system models within Spacetime to orchestrate dynamic wireless communication networks.
• Software Integration: Design and write production-ready "adapter layers" (primarily in Python or Go) to connect Spacetime with customer hardware.
• Data Modeling: Create and optimize data schemas (using Protobuf, JSON, gRPC) to map complex external network topologies.
• Link Analysis: Perform wireless communication system link budget analyses, wave propagation modeling, and coverage simulations.
• Operations & Triage: Act as the tier-3 escalation lead for live networks, diagnosing and resolving complex system integration issues.
• Product Collaboration: Work closely with the core Product and Software Engineering teams to translate custom integration patterns into reusable product features.

• Hybrid Technical DNA: Strong software engineering fundamentals paired with a solid understanding of physical-layer communications.
• Coding Proficiency: Hands-on software development experience and comfort passing an entry-level SWE coding assessment.
• Wireless Systems Foundations: Experience with wireless communication systems, including RF path loss, propagation, network topology, and link budgets.
• System Modeling Expertise: Practical experience developing or working with system/network simulation and modeling tools.
• Professional Experience: B.S. in Computer Science, Electrical Engineering, or equivalent practical experience, typically backed by 3+ years of professional engineering experience.
