Jobs at Quantiq

Design, optimize, and maintain low-latency C++ applications and infrastructure. Focus on concurrency, memory optimization, CPU affinity, hardware interactions, profiling/debugging, documenting architecture, and writing high-performance code in a fast-paced trading environment.

Maintain and operate in-house Fedora-based datacenter and desktop infrastructure. Provision, monitor, troubleshoot hardware and low-level software, manage access, backups, and failovers, and support operations and engineering teams with scripting and incident response.

Manage and optimize core IT infrastructure (servers, networks, storage, databases), provision and lifecycle systems, troubleshoot hardware/software/network issues, work with vendors for hardware procurement, and support operations including off-hour emergency response and disaster recovery testing.

Entry-level software developer working onsite in Austin to maintain and enhance production trading infrastructure. Tasks include writing high-performance C++/Python code, network packet processing, messaging and financial data processing, debugging, performance evaluation, large-dataset testing, and collaborating with Operations and Technical teams while owning projects end-to-end.

Develop and maintain hardware and low-level software across the network stack, from FPGA NIC packet processing and PCIe crossings to kernel socket engineering. Write and debug high-performance Verilog/SystemVerilog/VHDL and C/C++ code, evaluate system performance, test large datasets, collaborate with Ops and Technical teams, and manage project releases.

Design, optimize, and maintain low-latency, high-performance applications and infrastructure using C++ and Python. Profile and debug codebases, tune memory and CPU affinity, analyze network/packet behavior, document architecture and optimizations, and collaborate to sustain peak system performance.

Maintain and enhance a Linux-based, low-latency trading infrastructure: tune kernel and network settings, automate deployments, optimize hardware (FPGAs, network cards, switches), implement backups and failover drills, and respond to operational incidents in collaboration with Operations and Technical teams.

Design, optimize, and maintain low-latency FPGA-based network infrastructure. Develop Verilog/VHDL/SystemVerilog modules, write high-performance C/C++ network drivers, debug and profile systems, document architecture and optimizations, and improve overall system performance.

Work on production trading infrastructure in Austin, owning projects involving network packet processing, messaging specs, and financial data. Write high-performance C++ or Python, debug, analyze large datasets, collaborate with Ops/Tech, and deliver project updates.
