Tel Aviv, Tel Aviv, Israel Chain Reaction Full time $150,000 - $200,000 per year

Chain Reaction designs and builds hardware that fuels disruptive blockchain technologies by accelerating compute performance. Our world-class teams are transforming the future of data, creating the infrastructure that will power the next generation of secure, scalable, green computing. The main bottleneck in scaling cutting-edge solutions in privacy tech, data analysis, and real-time computing is acceleration – existing hardware cannot keep up with data processing needs. Chain Reaction's products reshape how data is processed and used on a global scale, and we're looking for the brightest people to join us.

As a Senior Software Architect, you will lead the design and integration of our software stack, ensuring seamless interaction between hardware-accelerated computation and embedded firmware running on ASIC, to high-performance system-level software orchestrating large-scale computations across multiple devices. You will work closely with hardware, cryptography, and software teams and be a key-decision-maker in software architecture choices, ensuring scalability, performance, and maintainability across the entire system.

We offer the Opportunity to deeply influence cutting-edge privacy-preserving technology with the highest performance.

Influence both silicon-level and large-scale system design

Work with highly skilled multidisciplinary counterparts

Responsibilities

  • Define the overall software architecture for multi-accelerator system integration.
  • Collaborate with the ASIC firmware team to ensure smooth HW/SW integration.
  • Create and maintain software design documents, API specifications, communication protocols and interface definitions.
  • Work with system software teams to design high-performance orchestration, scheduling, and data flow for FHE workloads.
  • Evaluate and integrate middleware, libraries, and frameworks that enhance performance and security.
  • Perform architectural reviews and provide technical mentorship to development teams.
  • Participate in hardware architecture discussions to influence ASIC feature definition from a software perspective.
  • Drive performance optimization, reliability, and scalability across all software layers
  • Guide software development teams on architectural best practices, coding standards, and system design patterns.
  • Contribute to strategic planning, roadmap development, and cross-functional alignment
Requirements
  • 10+ years in software engineering, including 5+ years in a software architecture or technical leadership role.
  • Proven experience in embedded systems and system-level software design.
  • Experience in multi-device or distributed systems architecture.
  • Experience with hardware-software co-design, embedded systems, or ASIC integration
  • Strong knowledge of C/C++ and Python.
  • Background in performance optimization for compute-intensive workloads.
  • Experience defining APIs, communication protocols, and software-hardware interfaces.
  • Familiarity with Linux internals, build systems, and deployment strategies.
  • Strong collaboration and communication skills, with ability to work across hardware, firmware, and software teams

Nice to Have

  • Experience with cryptography, FHE, or privacy-enhancing technologies.
  • Knowledge of RISC-V, RDMA, InfiniBand, or RoCE.
  • Experience with high-throughput computing, HPC, or GPU/accelerator programming models.
  • Familiarity with Yocto, Buildroot, or embedded Linux distributions.
