Principal Software Engineer, Cloud Platform

Echodyne Corp•Kirkland, WA

About The Position

Echodyne is seeking a Principal Software Engineer, Cloud Platform, to join our fast-growing team. You are a high-caliber technical leader who specializes in building the cloud-native "connective tissue" for complex radar ecosystems. You thrive at the intersection of distributed systems and real-time data ingestion, turning the massive output of edge radar systems into structured, actionable intelligence. As a technical shepherd, you guide the team to build a mission-critical backend that is "edge-aware"—designed to handle the unique telemetry, scale, and security requirements of a fast-growing fleet of radar assets.

Requirements

Expert-level proficiency in AWS cloud-native services specifically tuned for high-throughput device data (e.g., IoT Core, Kinesis, Timestream, Lambda).
Proven track record of leading the development of backends that "talk" to specialized hardware at the edge.
Deep experience in leading the design of resilient systems that can handle the bursty, high-frequency telemetry unique to radar systems while maintaining low-latency command-and-control loops.
Deep understanding of software security, specifically authentication (AuthN) and authorization (AuthZ) for remote devices, and data privacy frameworks to ensure secure transmission and storage of radar data.
Proven experience as a Tech Lead, moving between high-level system guidance and driving the implementation of complex backend services that support physical assets in the field.
A strong understanding of edge constraints. You understand how radar data is serialized and can lead the design of cloud schemas that account for intermittent connectivity and bandwidth limitations.
A clear history of driving technical teams to meet commitments and delivering customer-facing products in rapid R&D or aerospace/defense-adjacent environments.

Nice To Haves

You don't treat the cloud as an isolated silo; you lead the development of backend services specifically to solve the challenges of remote radar deployment and management.
You lead the building of systems that can handle the data load of a single radar unit as easily as a global fleet of thousands, ensuring the platform remains durable and supportable.
You ensure that encryption and identity management are baked into the ingestion pipeline, ensuring that every radar unit is a secure endpoint.
You move fast with a strong bias toward action, maintaining sound engineering judgment even when building "0 → 1" systems under tight timelines.

Responsibilities

Act as the technical lead for the cloud resources that ingest, process, and visualize data specifically from our edge radar units.
Research and prototype new backend technologies to improve how we manage radar systems, data updates, and real-time telemetry at scale.
Define and lead the implementation of rigorous authentication protocols for device-to-cloud communication, ensuring the platform meets high security and data privacy standards.
Work closely with the Principal Engineer (Edge IoT) to define the contracts and protocols that bridge the gap between on-radar logic and cloud-side resources.
Partner with the Engineering Manager to mentor the team, elevating engineering standards for design clarity and pragmatic practices across the radar-cloud stack.
