We are Twin Paradox Labs, a small startup with very big aspirations: To remove the technical barriers limiting scientific progress so that humanity’s greatest challenges can be overcome. We are developing hardware to transform quantum and atomic devices from academic experiments into real-world instruments, unlocking entire recent fields of research and discovery in applications as varied as greenhouse gas sensing, quantum computing, and space exploration. All of this starts by building precision electronics and optics to manipulate the internal structure of single atoms. That’s what we do.
In the past 8 months we have:
Launched a prototype laser system on a SpaceX rocket, enabling a quantum gravity sensor for earth observation
Demonstrated the viability of our laser technology in the application of greenhouse gas sensing
Delivered our first product, a robust and compact laser system, to a Government of Canada Defense organization
If you have a “can-do” attitude, want to be constantly learning and trying new things, and want to build the best possible tools to explore and protect our world, we would love to hear from you.
The Role We are looking for an FPGA / Embedded Design Engineer to join our team. In this role you will play a vital part in the development of Twin Paradox Labs’ laser systems, focused on both R&D; and product development. You will be a leader within our small startup team, taking responsibility for Xilinx Zynq development work while working closely with team members in other disciplines to deliver impactful electro-optic products.
You will implement new control algorithms, command structures,



and digital signal processing in FPGAs and on ARM cores, and help implement fault tolerance and remote operation to enable laser system use in harsh terrestrial conditions all the way to CubeSats and the ISS.
Responsibilities Implement and maintain FPGA code in VHDL and Verilog, and Linux scripts and drivers for Zynq-7000 architecture
Develop in both PS and PL sides of Zynq series FPGAs
Work within an embedded Linux environment and write code in C, shell, and Python
Develop and implement control techniques (PID, Kalman, etc.) using DSP (filters, modulations, etc.)
FPGA design, simulation, synthesis, constraints, clock domain crossing, and timing analysis and closure
Work with a scripted workflow using TCL, Makefile, and shell
Explore software defined radio techniques and interfacing with ADC/DACs and SDR transceivers
Simulation, integration, and lab debugging
Architecture, design, and test documentation development
Participate in and lead design reviews
Contribute to best practices and methodologies definition
Experience Bachelors Degree in relevant Engineering specialty or equivalent
5+ years FPGA development and hands on lab experience
Experience with Xilinx products and Linux
Experience with AXI bus protocol
Familiarity with high speed SERDES
Familiarity with SPI,



I2C, UART, Ethernet protocols
Experience with git version control
Comfortable working with a multi-disciplinary team
Familiar with a structured product development process
Experience with design requirements capture, analysis, and tracking
Comfortable debugging, testing, and verification of new and legacy designs, and supporting their integration into working hardware
Nice to Have Skills C / VHDL co-simulation
Verification with UVM or VHDL
Experience with TCP protocol and developing Python GUIs an asset
Hobby projects with FPGA / Microcontrollers / Raspberry Pi / etc.
About You Self-motivated and able to work independently, strong time management skills to reliably deliver solutions within budget and on time
Excited to collaborate with other engineering and science disciplines
Strong, efficient, and systematic troubleshooting and debugging skills, and proficiency with typical lab equipment
Inherently curious with a strong desire to learn new fields (Quantum/photonics/sensing applications) and develop and deploy new techniques for them
Details Job Type: Full-time
Compensation: $80,000 to $120,000 annually plus employee stock options
Environment: Primarily in-office/lab, with occasional remote-work flexibility
Note: The successful candidate will be required to obtain a security clearance to work on projects with the Canadian government which may include providing proof of Canadian citizenship or permanent residency. Please only apply if you believe you will be able to obtain security clearance.
