About us:
Nexstem
is building the Human Body API — a non-invasive technology that reads and interprets brain andbody signals in real time. Founded in 2020, we create biosignal-powered infrastructure enabling applicationsacross health, performance, research, and human–computer interaction. Backed by global partners andrecognized by leading platforms, we’re making the human body machine-readable and accessible to theworld.
Role: Principal Architect Engineer — Systems, Compiler & OS-Level
Location: Bangalore
About the Role:
As part of our mission to democratize neurotechnology, we are seeking a Principal Architect Engineer tolead the design of performance-critical, low-level system software that sits close to our hardware stack andpowers the real-time Human Body API. This role is ideal for someone who has deep expertise in C++ systemsprogramming, OS/kernel fundamentals, compiler/toolchain awareness, and hardware–software integration,and who thrives at the intersection of neuroscience, embedded systems, and scalable real-time computing.As Principal Architect Engineer, you will architect, implement, and optimize the core system layer from devicedrivers and real-time data pipelines to system services and API abstractions.
You will work across:
- Compiler and toolchain optimization
- OS-level and kernel subsystems
- Real-time signal acquisition
- High-performance C++ runtimes
- Embedded and edge-level architectures
You will provide strong technical leadership, mentor engineering teams, and collaborate closely withhardware, firmware, algorithms, and AI researchers.
Key Responsibilities
- System Architecture & OS-Level Design
- Architect modular, extensible system frameworks that interface directly with hardware and firmware.
- Define low-level hardware/firmware/kernel/driver/API interfaces.
- Make critical architectural decisions balancing latency, throughput, and reliability.
- Drive compiler/toolchain optimization strategies for performance-critical paths.
- Core Low-Level Development
- Develop high-performance C++14/17/20 system components with a focus on:
○ Low-latency, real-time execution
○ Multi-threading, synchronization, lock-free structures○ Memory management, allocation strategies, and cache efficiency
○ Device drivers
○ Communication protocols○ Real-time signal acquisition and streaming pipelines
- Build OS-level abstractions and libraries that expose hardware capabilities to higher-level SDKs.
- Hardware–Software & Kernel Integration
- Collaborate with hardware teams on embedded interfaces and sensor data pipelines.
- Optimize software performance on:
○ Embedded Linux
○ RTOS environments○ FPGAs and edge processors
- Work with kernel subsystems, interrupts, I/O scheduling, and low-level performance tuning.
- Performance, Profiling & Reliability
- Profile and optimize systems across CPU/GPU/accelerator architectures.
- Use tools such as: gdb, perf, valgrind, ltrace/strace, eBPF.
- Implement production-grade reliability, fault-tolerance, recovery, and watchdog mechanisms.
- Leadership & Mentorship
- Define engineering standards, best practices, and system-level design docs.
- Mentor engineers in C++, systems programming, compiler-level thinking, and performance
engineering.
- Research & Innovation Alignment
- Stay current with cutting-edge work in:
○ OS internals and real-time computing
○ Compiler optimizations (LLVM, Clang, GCC)○ High-performance systems programming
- Translate algorithmic and neural-signal research into efficient runtime implementations.
Education
- Master’s in Computer Science/Engineering or related field.
- Exceptional Bachelor’s candidates may be considered.
Experience
- 10+ years in system-level C++ development, including OS-level, kernel, or compiler-adjacent work.
- Proven track record building complex, production-grade low-level systems.
Core Technical Skills
- Expert C++ (C++14/17/20): STL, templates, design patterns, metaprogramming.
- Strong understanding of:
○ Multi-threading & concurrency
○ Lock-free design and synchronization○ Memory models, allocators, and performance tuning
○ Linux Kernel development, device drivers, system calls, interrupts
○ Embedded Linux or RTOS○ Firmware interfaces, hardware bring-up
- Familiarity with toolchains and compilers (LLVM, Clang, GCC).
- Strong debugging and profiling chops (gdb, perf, valgrind, sanitizers).
- Experience with streaming, real-time signal processing, or high-frequency data acquisition.
Bonus / Good to Have
- GPU programming (CUDA, OpenCL, Vulkan compute).
- Rust or Python integration with C++ pipelines.
- Experience in neurotech, robotics, IoT, or any real-time hardware domain.
- Knowledge of DSP, numerical methods, or ML-based signal processing.
Soft Skills
- Strong systems thinking and ability to understand large, complex architectures.
- Exceptional problem-solving under tight latency/performance requirements.
- Cross-functional collaboration with hardware, AI, and product teams.
- Excellent communicator who documents clearly and leads by example.
