We're looking for an Infrastructure Engineer who thrives on squeezing every microsecond out of a system. You'll own the performance, reliability, and automation of our bare-metal trading infrastructure in an environment where latency is measured in nanoseconds, and every kernel tuning decision matters. If you're the kind of engineer who reads kernel changelogs for fun and has opinions about NIC ring buffer sizes.

Responsibilities:

• Own and optimize our bare-metal Linux infrastructure end-to-end — from BIOS/firmware settings through 
  kernel tuning to application-level performance.
• Implement and maintain precision time synchronization (PTP/PPS) across the trading environment, ensuring 
  nanosecond-level accuracy.
• Configure and tune kernel-bypass networking (Onload / OpenOnload, DPDK, or similar) for ultra-low-latency 
  market data and order paths.
• Profile and eliminate latency at every layer: hardware interrupts, CPU isolation and pinning, NUMA topology, 
  memory allocation, network stack.
• Build and maintain CI/CD pipelines and infrastructure-as-code for repeatable, auditable deployments across 
  physical hosts.
• Develop monitoring and observability tooling focused on latency distribution, jitter, and tail-latency anomalies 
  — not just uptime.
• Collaborate with quantitative developers and trading teams to understand workload characteristics and codesign infrastructure around them.
• Manage network infrastructure including switch configuration, multicast, and colocation connectivity where 
  applicable.
  
  

The Right Candidate:

• 4+ years in a Linux infrastructure, SRE, or performance engineering role — experience in an HFT or electronic 
  trading firm is strongly preferred.
• Deep Linux systems knowledge: kernel tuning (sysctl, cgroups, isolcpus, tickless kernels), scheduling policies, 
  memory management, and storage I/O.
• Hands-on experience with kernel-bypass networking — Solarflare/Xilinx Onload, ef_vi, DPDK, or similar 
  frameworks.
• Solid understanding of PTP (IEEE 1588), PPS, and time synchronization architecture at scale.
• Strong scripting and automation skills (Bash, Python) and experience with configuration management tools 
  (Ansible, Salt, or similar).
• Experience with CI/CD tooling (Jenkins, GitLab CI, or similar) in a bare-metal or on-prem context.
• Comfort working with hardware: server selection, NIC selection and firmware, BIOS tuning, and colocation 
  environments.
• Familiarity with performance profiling tools: perf, ftrace, flamegraphs, eBPF/bpftrace, cyclictest.
  
  

Bonus:

• Experience with FPGA-based networking or hardware timestamping.
• Knowledge of market data protocols (ITCH, OUCH, FIX) or exchange connectivity.
• Familiarity with InfiniBand or RoCE fabrics.
• Experience with compliance and security standards relevant to financial environments (ISO 27001, SOC 2).
• Exposure to container technologies (Docker, Kubernetes) for non-latency-critical workloads and tooling

As a Software Engineer at Barak Market Making, you will play a crucial role in building and scaling the core engine of our algorithmic trading platform. You won't just be building features or user interfaces—you will dive deep into system architectures, memory management, and Linux OS internals to squeeze microsecond-level efficiencies out of our automated trading infrastructure.
You will work in a fast-paced, highly collaborative environment alongside quantitative traders, hardware engineers, and systems administrators to design and maintain high-frequency trading (HFT) systems across global markets.
Key Responsibilities
• Design, build, and maintain high-performance, low-latency core trading components, focusing on IPC, memory optimization, thread management, and network I/O rather than application-level GUIs.
• Collaborate with Linux and network engineers to optimize kernel socket buffers, hardware integration, and system-level configurations for maximum throughput and reliability.
• Partner directly with quant traders and researchers to translate trading strategies into ultra-fast, deterministic production code.
• Take end-to-end responsibility for complex infrastructure projects—from architectural design and bench-marking to CI/CD automation and production monitoring.
• Articulate complex technical trade-offs, system behavior, and low-latency bottlenecks clearly across both technical and non-technical teams.
The Right Candidate 
• 3+ years of professional software engineering experience in C++ or Java, demonstrating a sustained track record of ownership and impact on mission-critical systems.
• Deep knowledge of low-level software engineering—including memory layout, concurrency models, Linux OS internals, kernel profiling, and low-latency optimizations.
• Proven ability to thrive in a collaborative team environment, sharing knowledge, engaging in rigorous code reviews, and working toward shared platform goals.
• Exceptional verbal and written communication skills with the ability to explain complex low-level concepts simply.
• Strong autodidactic drive and problem-solving initiative, comfortable taking ownership outside the rigid silos of corporate environments.
Nice to have:
• (Basic) understanding of financial markets infrastructure, order books, and exchange protocols.
