✨ AI‑Generated
An experienced systems engineer role bridging native technologies and web platforms. The position involves building frameworks and tools that combine high-level development with native performance.
Highlights
Opportunity to work on innovative web and native technology infrastructure with significant technical ownership.
Description
Systems Engineer – Web Platform
Summary
We’re Pax Andromeda, a well-funded startup based in San Francisco.
We’re building a new open-source application engine on top of web technologies, and we're looking for an experienced engineer with a deep background in both web tech and native application stacks.
Responsibilities
We are looking for a hybrid web/systems engineer with experience in both C++ and JavaScript.
We are developing frameworks and tooling that bind native system primitives to high-level constructs, based on WebKit, pushing as much implementation as possible up into the JavaScript layer (and maintaining native performance).
We move between the two sides of the stack daily, so comfort in both is essential.
The problem domain is expansive and multidisciplinary.
You will build and own significant portions of the product but we don’t expect you to come in with knowledge across 100% of the surface area.
You will be a great fit if you have deep experience in two or more focus areas in the list below and are comfortable owning them on both sides of the native/JS boundary.
This list is by no means exhaustive.
Skills
Requires experience in both C++ and JavaScript.
JS engine embedding and bindings: JSC / WebCore embedding (or V8/SpiderMonkey/similar), code generation, libclang, IDL, marshalling between native and JS types Graphics: Skia, Metal, Vulkan, CoreGraphics, WebGPU, web and system compositorsMedia playback: hardware decoding (VideoToolbox, VA-API), GStreamer, direct scanoutNetworking: libcurl, QUIC, OS networking primitives, split network-process architecturesWayland: client and server implementations, extensionsWindows: application frameworks, drivers, WINE, DirectXIPC: shared memory, UNIX domain sockets, Mach ports, D-Bus, command serializationBuild tooling: CI, CMake, multi-platform builds, artifact distributionVirtualization: virtio, libvirt, hypervisorsDebugging: LLDB, gdb, Chrome Dev Tools protocolSecurity and performance: cross-cutting across any of the above
You Might Be a Good Fit If
You have a passion for delivering high quality experiences to usersYou have experience in a similar stack or problem spaceYou have experience building concurrent software systemsYou have the ability to find creative solutions to complex performance problems: the web platform lets developers do crazy things, users expect things to be fast even if the website wasn’t built in the most optimal way.You care about company culture, engineering culture, and best practices.
