Job Description

Architect modular, extensible software frameworks for BCI hardware and companion applications.

Define system-level interfaces between hardware, firmware, signal-processing, and APIs.

Make critical design trade-offs balancing performance, scalability, and maintainability.

Core Development

Develop high-performance C++ software (C++14/17/20) with a focus on low-latency, multi-threaded, and memory-efficient applications.
Implement hardware drivers, communication protocols, and real-time signal acquisition pipelines.
Build abstractions and libraries that expose Nexstem s hardware capabilities to higher-level SDKs and APIs.
Be strong in core Computer Science fundamentals and architecture.

Hardware-Software Integration

Collaborate with hardware engineers on device drivers, data acquisition interfaces, and embedded systems.
Optimize performance on embedded processors, FPGAs, Linux-based systems, and edge computing devices.

Performance & Reliability

Profile and optimize system performance across CPU/GPU/accelerator architectures.
Implement reliability, fault-tolerance, and recovery mechanisms for production-grade deployments.

Mentorship & Leadership

Set coding standards, best practices, and CI/CD workflows for the engineering team.
Mentor junior and mid-level engineers in C++, software design, and system thinking.

Innovation & Research Alignment

Stay up-to-date with advances in real-time computing, compilers, and systems programming.
Collaborate with algorithm and AI researchers to translate signal-processing pipelines into efficient runtime implementations.

Requirements
Education

Master s degree in Computer Science & Engineering or a related field.
(Bachelor s with an exceptional track record may be considered).

Experience

5+ years of professional experience in C++ system-level development.
Proven track record in designing and delivering complex, production-grade software systems.

Technical Skills

Expert-level C++ (C++14/17/20): STL, templates, modern design patterns.
Strong knowledge of multi-threading, concurrency, synchronization, and memory management.
Experience writing low-level code: device drivers, firmware interfaces, or embedded Linux/RTOS.
Deep understanding and experience in Linux Kernel development and low-level operating system concepts.
Familiarity with hardware communication protocols (USB, BLE, Wi-Fi, nRF, SPI, I2C, etc).
Experience in performance optimization, debugging tools (gdb, valgrind, perf), and profiling.
Exposure to real-time systems, signal acquisition, or streaming data pipelines.

Bonus Skills (Good to Have)

GPU programming (CUDA, OpenCL, Vulkan compute).
Experience integrating C++ with Python or Rust in hybrid pipelines.
Prior work in neurotech, robotics, IoT, or other real-time hardware-adjacent domains.
Familiarity with numerical methods, DSP, or machine learning integration.

Soft Skills

Strong systems thinking: can see the big picture and design for scalability.
Exceptional problem-solving skills under performance/latency constraints.
Ability to work cross-functionally with hardware, AI, and product teams.
Clear communicator who can mentor, document, and lead by example.

Compensation & Benefits

Competitive compensation with growth opportunities.
Opportunity to define and shape the core software architecture for a cutting-edge neurotech platform.
Work alongside an elite team at the intersection of hardware, neuroscience, and AI.
Flat hierarchy, ownership-driven culture, and the freedom to experiment and innovate.
