Job summary

Barak Capital Ltd. is seeking a Software Engineer to design and scale the core engine of our high-frequency trading platform.

You will work on low-latency components, memory management, and Linux internals to squeeze microsecond-level efficiencies in a fast-paced, globally traded environment. You'll collaborate with quantitative traders, hardware engineers, and systems administrators to ensure maximum throughput and reliability across multiple markets.

Qualifications

• 3+ years of professional software engineering experience in C++ or Java.
• Deep knowledge of memory layout, concurrency models, Linux OS internals, and low-latency optimizations.
• Experience collaborating in cross-functional teams and conducting rigorous code reviews.
• Strong ability to explain complex low-level concepts clearly.

Responsibilities

• Design, build, and maintain high-performance, low-latency core trading components (IPC, memory optimization, thread management, network I/O).
• Collaborate with Linux and network engineers to optimize kernel buffers and system configurations for throughput and reliability.
• Work with quant traders to translate strategies into fast production code.
• Lead architecture decisions from design to CI/CD automation and production monitoring.
• Communicate trade-offs and bottlenecks clearly across technical and non-technical teams.

Job description

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.

What We Offer:

• Breakfast, fresh coffee, and daily meal allowance in our office in Amsterdam Zuid
• Access to gym facilities, travel reimbursement, or Lease-a-Bike program
• International environment and regular team events
