Senior Native Software Engineer Location: Kraków or remote in Poland Employment Type: only permanent contract of employment The role. Build Desktop Intercept - the native Windows driver and app that acts as a virtual mic/speaker, replaces audio in real time, and (Phase 1 Phase C) reads the DOM and drives Computer Use. This is the hardest engineering on the platform and the deepest moat. Everything you build feeds a high-efficiency, event-driven, low-latency distributed platform - voice, desktop, intelligence, and AI combined - so you think in latency budgets, throughput, and efficiency, not just features. Startup environment: 1-week sprints, Friday demos, fail fast and move forward. What you'll own. Windows native driver (WASAPI, virtual audio devices, kernel-adjacent hooks) · real-time bidirectional audio routing · the user-space app (audio router, DOM scraper, MCP server) · the desktop-to-cloud path onto the event bus (NATS-class, WebSocket) under a sub-300ms budget · AV co-existence and mass-deployment · your committed timelines. Who you are. Self-starter, hacker, grit. You consider yourself exceptional at the systems level and can show it. You love new technology, adapt fast when it changes, demonstrate ideas with working code, and use AI tools daily to multiply your velocity. Team player who makes and hits committed timelines. Loves solving the problems nobody else can - and winning. Requirements 8+ years systems / native development; shipped a Windows desktop agent at real scale (>10k seats) with audio. Strong C/C++ - mandatory. Strong Go for the service side - mandatory. Comfortable building and interacting with drivers - virtual audio devices, virtual microphones/speakers, WASAPI / Core Audio, kernel-adjacent hooks. Real-time audio pipelines under a sub-300ms budget - buffering, resampling, drift, glitch-free capture/playback. Understands high-efficiency systems end-to-end - event-driven architecture, pub/sub, WebSocket streaming, and what state, race conditions, and locking mean at the native layer (lock-free audio buffers, real-time threads, priority inversion). macOS / Linux native experience is a huge +++++ - cross-platform desktop is where this goes next. Browser / DOM internals and process injection a strong plus (Phase C). Enterprise mass-deployment craft - MSI/installer engineering, silent deploys, fleet upgrades across 10k+ locked-down seats. Driver/code signing and AV/EDR co-existence - WHQL, EV certs, and staying invisible to CrowdStrike-class agents without tripping them. Crash-dump and telemetry discipline - WinDbg/minidumps, symbolized crash reporting from the field; you debug machines you'll never touch. Security posture - least privilege service design; this app listens to customer audio and reads screens, so it must be provably tight. A master debugger at the systems level - kernel logs, crash dumps, audio glitches, AV interference; you see it. SIP / RTP a strong plus. Mid-tier or better hands-on AI-in-product experience a plus (the desktop app hosts an MCP server and drives Computer Use).

That number is real. WorkMundi's database shows 144,883 open engineer roles across the world. India has the most with 31,687 jobs, followed by the United States with 30,084. If you just finished reading one job ad and felt paralyzed by choice, you're not alone—but this scale is actually an advantage. It means you can afford to be selective.
Start by geography and language. The majority of engineer ads—117,837 of them—have the job posting text written in English. Use that as one filter, but remember: the ad text language tells you nothing about whether the role actually requires you to speak English day-to-day. Read the job description carefully. Then check which countries have the volume you're targeting. Singapore, Poland, and Australia round out the top five after India and the US.
Next, learn who's hiring. Accenture has posted 2,801 engineer roles. andurilindustries, speechify, and jobgether are also actively recruiting. If you're applying to one of these names, research their hiring patterns and interview style before you apply. That homework pays off.
When you interview, expect the question every engineer hears: 'Tell me about a time you had to debug a problem that wasn't in your job description.' Have a specific story ready—not a general one. Name the tools, the deadline pressure, and what you learned. Hiring managers listen for whether you see problem-solving as part of the role itself, not a favour.
