RF Signal & Telemetry Systems Engineer

Type: Full-Time

About Dominion Dynamics

Dominion Dynamics is building Canada’s first modern defence prime: software-defined, attritable, and sovereign.

We believe tomorrow’s military power won’t hinge on exquisite platforms, but on the seamless coordination of adaptable, AI-driven capabilities across every domain. We’re building that family of systems, fielded with operators, sovereign by design, and accountable to Canada’s democratic values.

We move fast, deploy with the CAF, especially in the Arctic, and operate with uncompromising respect for Canadian law, treaty obligations, and the CAF community.

Our founding team includes former operators from Anduril, Google, Amazon, and the Canadian Armed Forces. We’re building hard tech in hard places, and we're looking for system-level thinkers who thrive at the intersection of autonomy, aerospace, and national security.

Why This Role Matters

Tactical networks are the foundation of deployed platforms; they must deliver secure, low-latency connectivity across heterogeneous links and constrained environments. This role moves prototype network capabilities into hardened, field-ready software and tooling that preserve connectivity, situational awareness, and mission continuity under degraded or contested conditions.

The Role: RF Signal & Telemetry Systems Engineer

You will drive network stack development and integration across edge platforms, implementing reliable transports, data serialization, configuration tooling, and validate network performance through testing and field trials.

Note: This role includes a forward-deployed mandate. You’ll work hands-on with deployed systems and operators in real-world environments.

What You'll Do:

Design and implement networking components for edge systems; focus on reliable data transport, link resilience, and telemetry forwarding.
Build tooling and automation for network configuration, deployment, and recovery using JSON, YAML, and shell tooling.
Implement and optimize protocol handlers, data serializers, and interoperable interfaces in Python, Go, or C/C++ as appropriate.
Integrate network software with embedded firmware, gateway services, and backend pipelines; ensure graceful behaviour under intermittent connectivity.
Develop automated tests, simulation scenarios, and CI pipelines that validate network behaviour at scale.
Instrument observability for network health; produce logs, metrics, and diagnostics to support on-call and field troubleshooting.
Collaborate with software and hardware teams to define secure defaults, authentication, and operational procedures.
Support field deployments and iterative tuning based on live network performance and operator feedback.
Ship Android-adjacent operator connectivity features; support ATAK data channels and plugin interfaces.
Design cloud backhaul and diagnostics on AWS; expose health and telemetry APIs for operator tools.

What You’ll Bring

Bachelor’s or Master’s in Computer Science, Computer Engineering, or equivalent practical experience.
Mid-level: ~2-5 years building networked systems, networking stacks, or related software for constrained/embedded environments.
Strong programming experience in Python and at least one systems language (Go, C, or C++); familiarity with Java is useful.
Comfortable with configuration-as-code; experience authoring and parsing JSON and YAML; proficient with Bash for automation.
Practical experience integrating software with embedded systems, telemetry pipelines, and field-deployed hardware.
Experience writing automated tests and CI for network behaviour; strong debugging and diagnostic skills.
Experience with networking over constrained links; familiarity with radios and gateways used alongside ATAK ecosystems.
Pragmatic, low-ego engineer who can troubleshoot in the field and iterate quickly under operational constraints.
Eligibility for Canadian security clearance preferred; Canadian citizenship an asset.

Why Join Us

Building something meaningful starts with the right people.

At Dominion Dynamics, you’ll:

Shape Canada’s future by building real defence capability for the CAF and our allies.
Make decisions that ship in a high-trust environment with short feedback loops and rapid iteration.
Move fast, field faster, and work directly with the operator — our systems are in the field with the CAF now.
Have an impact from day one with equity, responsibility, and direct access to leadership.

If you’re curious, hands-on, and driven by the opportunity to make a difference, this is where you belong!

Compensation & Benefits

Competitive base salary and company equity
Comprehensive health benefits
Additional equity granted based on impact

We use AI tools to support parts of the hiring process, including screening and reviewing responses. Final hiring decisions are always made by people and follow all applicable privacy and employment laws in Canada.
