As Software Engineer, your key responsibilities include:

• Designing and maintaining the OS and software stack behind our trading hardware
• Building and supporting Python-based interface layers to control and monitor hardware systems
• Developing software for STM processors embedded on prototype boards
• Managing and supporting a fleet of hardware systems in a live production environment
• Collaborating closely with hardware, infrastructure, and trading teams to ensure seamless system performance
• Contributing to infrastructure automation and transitioning into embedded development and low-level hardware logic over time

What you’ll get:

• The opportunity to work alongside best-in-class professionals from over 40 different countries
• A highly competitive compensation package
• Global profit-sharing pool and performance-based bonus structure
• 401(k) match up to 50%

• 25 paid vacation days alongside market holidays
• Extensive office perks, including breakfast, lunch and snacks, regular social events, clubs, sporting leagues and more

Who you are:

• Strong foundation in computer science fundamentals and hardware systems
• Proficiency in Python, including familiarity with relevant libraries and APIs
• Experience writing software in C/C++
• Creative problem-solving skills at the system level
• Ability to collaborate with developers and researchers

Nice to have:

• Experience with low-level hardware/software interactions (drivers, buses, pins, registers, etc.)
• Ability to read and interpret datasheets and electrical engineering schematics
• Familiarity with devices and drivers in Linux
• Experience with FPGA design using VHDL/Verilog and the Vivado suite of tools
• Knowledge of communication protocols, especially Ethernet
• Exposure to network equipment operating systems like Cisco IOS, Arista EOS, or Juniper MOS
