What You’ll Be Doing 👨💻👩💻 🛰 🛰
You will be responsible for developing the backend Command & Control (C2) software that connects Quindar’s platform to satellite vehicles. Quindar enables users to operate large, heterogeneous constellations, and in this role you will build the systems that allow an ever-growing variety of spacecraft to communicate reliably with our platform while abstracting that complexity away from our users so they can focus on their core mission.
At its core, this is a machine-to-machine communications and systems integration problem. You will work with binary protocols, command and telemetry definitions, data transport, serialization and encoding, stateful communication, hardware interfaces, and the operational realities of communicating with remote systems where reliability matters.
You will bring or develop expertise in aerospace C2 concepts and industry standards such as CCSDS, CSP, CFDP, XTCE, and MIB. Direct experience with these standards is valuable, but it is not a prerequisite. We are equally interested in engineers who have solved similar problems in adjacent domains—including telecommunications, networking, robotics, industrial automation, IoT, defense systems, distributed infrastructure, or other complex hardware/software systems—and are excited to apply that experience to spacecraft operations.
You will collaborate with a multidisciplinary team to onboard new satellite vehicles into Quindar, translating spacecraft-specific interfaces and protocols into reliable, maintainable integrations with our platform. You will also help develop the abstractions, tooling, and architecture that allow us to support many different spacecraft without building every integration from scratch.
Ultimately, you will contribute to Quindar’s mission of simplifying space operations and enabling our customers to utilize their satellites like servers.
This is a hybrid role with 2 days in our Arvada, CO, Washington, D.C., or Seattle, WA office. We aim to maximize the benefits of in-person collaboration while maintaining a flexible schedule with a significant amount of remote work.
Tech Skills
Proficiency in backend or systems programming languages such as Python and Rust
Experience building software that communicates with, controls, or processes data from remote machines, embedded systems, hardware assets, or other complex systems
Experience implementing or integrating machine-to-machine communication protocols, including concepts such as binary serialization, framing, packetization, transport, message routing, sequencing, acknowledgements, error handling, and state management
Experience with real-time or embedded software, distributed systems, networking, telecommunications, robotics, IoT, industrial systems, or hardware/software integration
Experience with satellite communication standards such as CCSDS, CSP, CFDP, and IP is preferred but not required; experience implementing comparable protocols or communication standards in another industry is highly relevant
Familiarity with structured command, telemetry, or interface definitions such as XTCE and MIB is preferred; experience with analogous schemas, IDLs, protocol definitions, message catalogs, or data models from other industries is equally relevant
Understanding of the challenges associated with reliable communication to remote or intermittently connected systems, including bandwidth constraints, latency, retries, fault handling, and observability
Understanding and experience integrating encryption algorithms such as AES-256 GCM, AES-256 CFB, AES-256 ECB, NSA Type 1 PEGASUS, and NSA Type 1 CARIBOU is a plus
Experience with Kubernetes platforms and DevSecOps practices, particularly collaboration between software development and platform engineering teams, is preferred
Experience with relational and/or time-series databases
Familiarity with Git and GitHub or similar version-control workflows
Experience working with or contributing to open-source software is a plus
Soft Skills
Strong technical analysis, systems thinking, and troubleshooting skills
