Company Description:
Aistech Space is focused on generating affordable, recurrent, high-resolution thermal imagery of the planet to provide a new perspective of Earth’s changing resources. The company is based in Barcelona and aims to revolutionize remote sensing for environmental monitoring and resource management.
What you will do:
Aistech Space is seeking an expert FPGA Verification & Validation Engineer to build, lead, and execute the verification strategy for our next-generation image acquisition and processing payloads. Instead of designing the logic fabric, your primary mission will be to ensure the absolute reliability, timing compliance, and functional flawless performance of the “digital brain” of our systems before flight deployments.
You will architect and build advanced simulation frameworks and hardware-in-the-loop (HIL) testing infrastructures from scratch. Acting as the ultimate quality gatekeeper, you will test and push VHDL logic, AI engine integrations, and high-speed data paths to their limits, ensuring our satellite payloads operate with 100% predictability in the harsh environment of space.
In this role, you are expected to work as a team, functioning as an agile, highly collaborative unit focused on short, client-driven development iterations, while enforcing internal standards and good practices in project management, documentation, and time management.
The key objectives to be achieved in this position are:
- Understand Mission Objectives : Align FPGA validation protocols deeply with overall Aistech Space mission objectives.
- Advanced Verification Frameworks: Design and implement self-checking testbenches and advanced simulation environments utilizing UVVM, OSVVM, or UVM to comprehensively verify complex VHDL designs.
- Toolchain & Simulation Mastery: Run exhaustive functional and timing simulations using Xilinx Simulator (XSIM) or third-party tools like ModelSim/Questa, leveraging Xilinx Verification IP (VIP).
- High-Speed I/O & Connectivity Testing: Test, characterize, and debug high-speed transceivers (GTH/GTY) and critical interfaces like MIPI CSI-2, PCIe Gen3/4, and 10G/25G Ethernet.
- Data Path Validation: Formally verify low-latency data movement pipelines involving AXI4-Stream, AXI SmartConnect, and Xilinx Video DMA (VDMA) or DataMover IPs.
- Hardware-in-the-Loop (HIL) Debugging: Lead bench-level and flight-model hardware verification campaigns using Vivado ILA (Integrated Logic Analyzer), Vitis Analyzer, and standard laboratory equipment (oscilloscopes, logic analyzers).
- Timing Closure Verification: Critically review complex XDC constraints, analyze multi-clock domains managed by MMCM/PLLs, and validate timing margins on high-utilization designs.
- AI Engine & Memory Validation: Verify the robust deployment of neural networks through Vitis AI flow and validate hardened DDR4/LPDDR4 memory controllers under multi-stream 4K/8K video loads.
- Automation Strategy: Drive verification efficiency by developing automated testing script suites in Tcl for Vivado and Python for data/test results analysis.
- Documentation & Reporting: Actively engage in the development of comprehensive validation plans, test reports, and specification manuals to build out company procedures, and author technical articles for Aistech News or the company blog.
Who you are:
Must:
- Degree : BSc/MSc in Electronics, Telecommunications, Computer Science, or similar.
- Verification Expertise : Proven professional experience in advanced FPGA verification methodologies (UVVM, OSVVM, or UVM) and building modular, scalable testbenches.
- AMD Toolchain Proficiency : Solid experience within the AMD/Xilinx eco-system, including Vivado Design Suite, Vitis Unified Software Platform, and associated simulation environments.
- Protocol Familiarity: Strong working knowledge of the AXI4 protocol family (Memory Mapped, Stream, and Lite) and structural design verification patterns.
- Scripting Power: Fluency in Python for test automation and scripting, as well as Tcl for tool workflow automation.
- Fluent in English: Excellent communication skills for global, multidisciplinary collaboration.
Nice to have:
- Versal & HLS Exposure: Familiarity with validating Versal AI Engines (AIE), Programmable Network on Chip (NoC), or testing Vitis HLS generated blocks.
- High-Reliability Industry Experience : Prior exposure to NewSpace, aerospace, or defense industries, including knowledge of Single Event Upset (SEU) mitigation and radiation-hardened testing philosophies.
- Hardware Bring-up: Basic experience with SerDes calibration and eye-diagram analysis.
