Test Engineer – Connectivity Testing

ABOUT US STARK is a new kind of defence technology company revolutionizing the way autonomous systems are deployed across multiple domains. We design, develop, and manufacture high-performance unmanned systems that are software-defined, mass-scalable, and cost-effective. This provides our operators with a decisive edge in highly contested environments. We’re focused on delivering deployable, high-performance systems—not future promises. In a time of rising threats, STARK is bolstering the technological edge of NATO Allies and their Partners to deter aggression and defend Europe—today. ABOUT THE TEAM As a Datalink Integration & Test Engineer , you will play a key role in bringing together complex software systems that power our next generation of autonomous platforms.  YOUR MISSION Your mission is to take established, proven MANET (mobile ad-hoc network) radio systems and make them work — reliably, repeatably, and under real-world constraints — inside our unmanned platforms. In this role you focus on the datalinks for our close- and short-range loitering effector and ISR systems, where the link has to stay solid through fast-moving, time-critical mission profiles in contested airspace. You own the path from "commercial radio in a box" to "integrated, tested, mission-ready datalink." This is a hands-on integration and test role at the boundary of RF hardware, networking, and platform architecture. You own two connections that have to hold up when it counts: the command-and-control link between UAV and ground control station (GCS), and the mesh that lets multiple effectors operate as a coordinated swarm. You aren't just wiring in a radio; you are certifying that command and control survives contact with the real world, and giving the engineering team the hard data to trust it. RESPONSIBILITIES INTEGRATION * Integrate established MANET / mesh radio systems (e.g., Silvus StreamCaster, Persistent Systems Wave Relay, Rajant, Radionor) into STARK's platform architecture across the mechanical, power, RF, and network/software interfaces. * Define and implement the integration approach for each datalink — antenna placement, RF front-end, IP networking, and interfacing with the autopilot and payload stack. * Integrate and configure the UAV-to-GCS command-and-control link, ensuring reliable telemetry, control, and video across the full mission profile through to the terminal phase. * Set up and tune multi-node mesh topologies that enable UAV-to-UAV connectivity and coordinated swarm operation of multiple effectors, including relay and self-healing behaviour. * Work closely with hardware, autopilot, and systems engineering to ensure the communication subsystem is correctly matched to the platform and its constraints. TEST & VALIDATION * Design and execute structured test campaigns — bench, hardware-in-the-loop, and field trials — to validate datalink behaviour. * Characterise link performance across throughput, latency, range, mesh routing behaviour, and resilience under interference and degraded conditions. * Validate swarm behaviour at the network level — multi-node mesh scaling, UAV-to-UAV and UAV-to-GCS connectivity, relay hops, and graceful degradation as nodes join, move, or drop out. * Build up repeatable test procedures and instrumentation, and produce clear, traceable documentation of setups, methods, and results. COLLABORATION & CONTINUOUS IMPROVEMENT * Translate field and test findings into concrete integration and configuration improvements. * Support trade-offs and selection decisions between candidate datalink systems with measured, defensible data. * Contribute to the evolution of STARK's communication integration standards and test methodology. QUALIFICATIONS EXPERIENCE & CERTIFICATIONS * Professional background in Electronics / Communications Engineering or a comparable technical field. * Hands-on experience integrating MANET / mesh radio or tactical datalink systems into a larger platform or system. * Practical test and measurement experience (spectrum analysers, RF link testing, network diagnostics). * Must be a citizen of a NATO member state (due to export control and security regulations). TECHNICAL BACKGROUND * Solid grounding in RF fundamentals and antenna/propagation basics. * Strong understanding of IP networking, routing, and the OSI model as it applies to mesh and point-to-point links. * Comfortable working in Linux networking environments and debugging at the hardware/software boundary. * Structured, disciplined approach to test design, execution, and documentation. PROFILE * Strong written and verbal communication skills in English. * Analytical, thorough, and outcome-oriented — you want the integration to be clean and the results to hold up, not just to work once. NICE TO HAVE * Hands-on experience with specific MANET vendor ecosystems and their management/config tooling. * Knowledge of tactical datalink bands, waveforms, FHSS, and encryption. * Familiarity with military communication standards and secure over-the-air transmission. * Scripting / embedded experience (Python, C++) for test automation and instrumentation.

YOUR OPPORTUNITY: Make a real difference in the blockchain industry! Build the change you want to see. Veridian is building the infrastructure layer for digital identity. Born as a Cardano Foundation initiative, our technology already powers credential issuance and verification across regulated industries. We are looking for an SDET to join a small, high impact team. You will shape quality from the ground up across everything we ship: the Veridian Wallet, enterprise credential management applications, cloud based backend services and open source protocol libraries. Our stack builds on the open protocols KERI and ACDC using components such as KERIA (Python), Signify-TS and Signify-Java. You will wear multiple hats, in a highly complex domain. Some weeks that means writing test automation frameworks. Other weeks it means jumping into CI/CD pipelines, debugging a flaky mobile build, reviewing security sensitive code or helping define acceptance criteria for a feature that did not exist last month. In this role you will: * Design and implement end to end, integration and API test automation frameworks. * Build CI/CD quality gates that catch regressions before they merge. * Obsess over edge cases: revoked keys, out of order events, race conditions. * Test across Veridian’s full product stack: wallet, services, libraries.  * Collaborate with frontend and backend engineers to improve testability. * Own test environments, test data management and reporting. YOUR STORY: * 3+ years in an SDET or test automation role. * Strong hands-on experience developing production grade automation frameworks in languages like TypeScript and Java. * Familiar with mobile testing (Appium, Maestro or similar). * Background in security sensitive systems (key management, cryptographic operations). * Exposure to fault tolerant domains (out of order messaging, connectivity failures). * Comfort with CI/CD pipelines (GitHub Actions preferred), containers (Docker) and lifecycle tooling (Git, Jira/Confluence). * Self motivated, independent and thorough in finding what others miss. YOUR IMPACT: * Ensure the reliability and security of identity systems used by governments and enterprises. * Build lean, automated pipelines that let a small team ship fast without compromising quality. * Define quality standards that become the team's standards. NICE TO HAVE: * Fluency with AI tools to write tests more efficiently, generate edge cases and expand coverage. * Industry experience in cryptography and key management. * Familiarity with decentralized identity protocols and systems. * Performance and load testing experience. * Experience in a startup environment where speed, ownership and adaptability matter more than process.
