Job summary

HushOne, Inc. is seeking an experienced systems engineer to ensure our local runtime remains dependable as workload increases.

You will build supervision, isolation, and storage integration, while diagnosing scheduling, memory pressure, and driver interactions across supported OSes. In the first 90 days you will ship a supervised local runtime that survives restarts, respects resource budgets, and provides useful diagnostics without exposing personal content.

Qualifications

• Strong operating-systems fundamentals: scheduling, memory, I/O, and where they interact
• Practical systems programming in Rust, C, C++ or comparable
• You can describe how you debugged a real concurrency, memory or performance problem, in detail
• Instinct for the machine's behaviour under sustained load rather than in a benchmark

Responsibilities

• Build process supervision, resource isolation, permissions, storage integration and background execution
• Diagnose problems across CPU scheduling, memory pressure and device drivers
• Respect the capabilities and restrictions of each supported operating system

Job description

You work close to the operating system, and your job is that the person's computer stays dependable exactly when the agent is busiest and they need it most. Scheduling, memory pressure, and the behaviour of the machine under sustained load are the product here, because an agent that makes your laptop unusable is an agent you turn off.

The work:

Build process supervision, resource isolation, permissions, storage integration and background execution. Diagnose problems across CPU scheduling, memory pressure and device drivers. Respect the capabilities and restrictions of each supported operating system.

What good looks like:

In your first 90 days, ship a supervised local runtime that survives restarts, respects resource budgets and produces useful diagnostics without exposing personal content.

Evidence we look for:

Bring strong operating-systems fundamentals and practical experience in Rust, C, C++ or comparable systems tools. Show how you debug concurrency, memory or performance problems rather than listing languages.

Required:

• Strong operating-systems fundamentals: scheduling, memory, I/O, and where they interact
• Practical systems programming in Rust, C, C++ or comparable
• You can describe how you debugged a real concurrency, memory or performance problem, in detail
• Instinct for the machine's behaviour under sustained load rather than in a benchmark

Nice to have:

• Kernel or driver work
• macOS or Linux internals specifically
• Real-time or latency-sensitive systems

The exercise:

Investigate a service that stalls under memory pressure and propose a recovery design that preserves acknowledged work.

How we work:

We work together in the office, five days a week, and you can be based at any of our garages: Kirkland Garage (Kirkland, WA); UAE Garage (Dubai, Dubai). We hire across the United States , India , and the UAE . We are remote-friendly around family: if you need to work from home some days to look after the people you love, we arrange that with you one person at a time, and we encourage people to use it rather than tough it out.

Pay:

We publish what we pay. Indicative ranges by market and level are on our compensation page, and they are realistic going market rates rather than headline numbers. Wherever we hire we pay at least the local market rate, and for full-time roles our floor is a living wage, never the statutory minimum. Compensation is reviewed every year and on promotion.

Equity:

Every full-time teammate gets stock options. Four-year vesting with a one-year cliff, sized to role, level and impact, and confirmed in writing at offer. High performers earn refresh grants.

Bonus and commission:

An annual performance bonus tied to clear company and personal goals, indicatively 10 to 20 percent of base for non-sales roles. Customer-facing roles carry on-target earnings, typically a 50/50 split of base and variable, with uncapped commission and accelerators above quota.

Health and peace of mind:

Medical, dental and vision for you and your family, plus life and disability cover. We have chosen the highest plan tier available to us rather than the cheapest one that clears the bar, because the point of this is that you never have to think about it. The specific plan numbers are confirmed in your offer letter.

401(k) with company matching:

A 401(k) with a company match, so the years you spend here compound into something that is yours whatever happens next. The match formula is confirmed in your offer letter.

AI tokens:

A budget of AI tokens of your own, because a company that says you should own your AI cannot be the company that rations it. Use them on the work and on whatever you are curious about.

Gym, and the everyday things:

A gym membership, and a corporate benefits programme with its own app, where you redeem real discounts with a long list of retailers on the ordinary purchases of a life.

Family:

We are remote-friendly around your family, arranged one person at a time, and we would rather you took it than toughed it out.

Referrals:

Refer someone we hire full-time who stays a year and you get $1,000 plus $10,000 in referral stock-based equity, on top of your own package.
