Role: UX/UI Designer (BAY AREA, CA - HYBRID) 1099 CONTRACT APPLY: https://vuetech.sh/careers

Ongoing contract across several B2B products on one design system. First pass is a fixed-price flows-and-kit package, then hourly as each product grows. Not a full-time seat.

Engagement: Ongoing 1099 contract. Milestone prices are set against a frozen spec. This is not a full-time seat.

First package: A fixed-price flows-and-kit package, about three weeks. After that, $50–75/hr as each product grows.

Location: SF Bay Area, hybrid, with in-person working sessions for kickoff and reviews.

Start: Immediately after selection.

Level: Mid-level welcome. You work directly with the founding CTO. Early sessions are for breaking the product down together. After that, scope is deliverable by deliverable.

ABOUT THE STUDIO: We are a small Bay Area product studio. Several products, one stack, one visual language. You own the UX with us: who the user is, what they are trying to finish, what belongs on each screen, and what happens when it fails. Later products reuse the same tokens, components, and patterns so customers and our engineers are not learning a new UI every time.

The products are B2B web apps: dashboards, media and content libraries, status views, and auth and access-gate states. The first product in the queue is a digital signage CMS. Store owners upload content, build playlists, pair outdoor Android screens from a phone, and see what is playing. The app is a mobile-first PWA. The screen on the sidewalk has its own states: setup QR, downloading, no content, and error.

You take a real part in that breakdown. Bring a point of view on structure, priority, and what to cut. Sit with us and map the flows before the high-fidelity screens exist. When a familiar admin layout is the wrong job for the task, say so and show the alternative.

The screens still have to ship. We start from a Tailwind UI / shadcn component kit. Buttons, inputs, tables, cards, and dialogs stay that anatomy, restyled with our brand: color, type, radius, and density. Page structure, hierarchy, and flow are yours. Every screen is composed from those components, with tokens that map to our Tailwind theme, so the frontend team builds from the system.

Qualcomm | Canada | Full Time | Remote(Canada)| QEMU

My team is looking to hire a software developer to help us design and extend QEMU support [1] for the Hexagon DSP [2]. We're looking for candidates who have experience coding in C, C++ or Rust* and who aren't afraid of rolling up their sleeves and poring over disassembled code. This particular architecture is a bit more challenging than most, because it's a bit unique. It's a VLIW [3], so it's a great opportunity to learn about an interesting architecture. Millions of Hexagon DSPs are out there, most are found in DragonWing/Snapdragon/DragonFly SoCs for Laptops, Android phones, cars and more!

We collaborate a lot with Open Source communities like QEMU, LLVM [4], the Linux kernel [5], and more. I love being able to work on Open Source software at my day job.

You can contact me directly (email addr is in my HN user link). If you don't have experience with QEMU - don't worry! Most of us didn't have any experience with it until recently, too.

The rest of the team you'd work with lives mostly in Canada, EU, US.

* Rust experience may serve the role well but we don’t (yet) have any product software in Rust.

Human8e Ltd | Applied cryptographer, protocol review | REMOTE (worldwide) | Contract, fixed fee

We're an early-stage UK company building a mobile application, funded by its founder (just me), which is why the scope below is deliberately narrow.

I'm looking for an applied cryptographer to review a protocol specification before it ships. It is small and specific: three messages, two parties, signature-based, using hardware-backed keys on both iOS and Android. It uses standard primitives only (ECDSA over P-256, SHA-256) and invents no new cryptography; the question is how they are combined. The specification is written and frozen, with test vectors and the generator that produces them.

What I want is a competent second opinion on whether it is sound: six specific questions answered in writing. Not an open-ended audit or a penetration test. The person I'm looking for has either published on protocol security or reviews protocols professionally; being good with crypto libraries isn't quite the same thing.

One piece of contract work, not a role. Under a short mutual NDA.

Email clive@human8e.com by Sunday 4 October with a short summary of the protocol analysis you've done, and I'll send scope, timing and what I'd need from you.
