Strello Health | Toronto (hybrid in-person/virtual)

Clinic Sales & Onboarding Lead | https://strello.health

Strello is an AI front desk for Canadian medical clinics. It answers calls, books and moves appointments, and works directly inside the clinic's EMR. We're physician-founded (I'm a practising rheumatologist), and the product came out of our own front-desk turnover problems.

What you'll do: - Own inbound leads and respond fast. Screen for fit first: are they on an EMR we integrate with, and is Strello the right answer for their phones?

- Run discovery and demo calls with physicians and clinic managers, then quote, close, send contracts and payment links, and keep the CRM current.

- Lead onboarding: workflow meetings with clinic staff, phone and EMR access, and launch coordination with our engineers.

- Stay the go-to contact after launch, and bring what you hear back to the product team.

You might be a fit if you've worked in sales, or clinic operations (MOA, coordinator, manager), or healthcare SaaS account management, or customer success.

You should be comfortable on the phone and on video with physicians, organized enough to run many clinics in parallel, and happy to help write the playbook at an early-stage company.

Apply: reza@strello.health with a few lines on the clinics or customers you've worked with.

Reducto is the agentic document platform for leading AI teams who need enterprise performance at scale. Most of the world's important information is locked in documents: PDFs, spreadsheets, scanned forms, financial filings. We build the infrastructure that lets AI read and work with them the way a human would, combining custom in-house models with leading frontier models to power accurate, efficient document workflows.

Our customers include AI teams like Harvey, Vanta, and Scale, along with enterprises across FAANG and top trading firms. We've grown revenue 8x year over year, partnered with hundreds of companies, and raised over $100M from a16z, Benchmark, and First Round Capital.

Zed Industries | North America, South America, Europe REMOTE | https://zed.dev/ Zed is a company for developers, by developers. All 3 of our founders have spent years in the trenches writing software and still do it almost every single day. We've raised $42M to support our ultimate vision, a new way to collaborate on software, where conversations about code remain connected to the code itself, instead of being tied to aging snapshots or scattered across different tools. The first step was creating a high-quality editor to serve as the user interface. Now this new investment lets us expand to tackle the next phase of our plan. We're developing a new kind of operation-based version control (https://delta.dev/) that incrementally tracks the evolution of your code with edit-level granularity, and we're integrating it into Zed to make collaboration, both with agents and teammates, a first-class part of the coding experience.

Paradromics | Embedded Software Engineer | Austin, TX or Oakland, CA | Onsite | Full-time

Paradromics is building a high bandwidth brain-machine interface for clinical use. The implant we built is restoring function to patients by streaming out neural data from specific brain regions in real time, which we convert to e.g. speech using machine learning. Check out our recent article in the NYT: https://archive.ph/C6CRb .

We're looking for help in further developing and hardening our embedded Linux components, which work in tandem with FPGAs and our custom ASICs to read out neural data. Some of the ongoing efforts are: HIL testing on real devices, integrating new sensor ASICs, maintaining our Yocto build system, exploratory work on prototypes, improving our clinical UX, and improving the core code that receives and massages data. The code is largely written in Rust with a little Typescript, (and bash, and bitbake recipes, etc).

You'll be expected to have experience constructing reliable and understandable software in Linux, and some level of experience in building and interacting with embedded hardware. Rust experience is ideal but not necessary. We're not looking for a specific number of YoE, but for motivated and hungry engineers who want to push the frontier of brain-machine interfaces.

To apply visit https://paradromicsinc.applytojob.com/apply/u5hXN4N9ID/Embed... or email your resume and a little about yourself to me, ehuber@paradromics.com . I'll be glad to hear from you!

Memorang | Product Engineers + Technical Project Manager | Full-Time | Los Angeles (or US remote for exceptional hires)

Help build the AI stack for education. Memorang gives teams the infrastructure to build, launch, and monetize AI-powered learning apps. We bootstrapped to profitability, were voted #1 among 1,500 in the Vercel AI Accelerator, and power products that collectively reach tens of millions of learners.

We’re hiring for two roles:

Product Engineers Own features from the first rough idea to production. You’ll work across AI workflows, backend systems, and user interfaces, making product decisions along the way. We’re looking for engineers who ask good questions, care about the details users notice, and can turn an ambiguous problem into something useful and shipped.

Stack: TypeScript, React/Next.js, React Native, Node.js, AWS Lambda, Postgres, and Neo4j.

Technical Project Manager Turn complex work into clear plans and keep delivery moving. You’ll coordinate across engineering, design, and customer needs, surface dependencies early, resolve blockers, and keep owners and timelines clear as priorities change.

Ideal background: an engineer who moved into project management, with startup experience and enough technical depth to discuss APIs, architecture, and AI workflows with the people building them.

Why join? A small team, meaningful ownership, and products used by millions. You’ll help shape what we build and how we work, with a short path from an idea to seeing it in users’ hands.

Remote-first, async-friendly, with health and wellness stipends, home-office support, and paid time off.

Apply: Email careers@memorang.com with your CV, a few sentences about what interests you, and something you’re proud to have built or delivered.

VIVA Finance | Atlanta, GA (In Person)| Front-End + Mobile Developer

VIVA is a Fintech Startup based in Atlanta, GA with the mission to build a more inclusive financial system. VIVA offers unsecured personal loans to customers who have traditionally been excluded and taken advantage of by the legacy financial institutions. The VIVA difference is to underwrite heavily on employment history and set up repayments through voluntary direct deposit payments from the borrower's paycheck. Our interest rates are less than 1/3 of the rates our customers are able to get from other financing options.

We are a VC backed company and have been in business for 7 years. We have been profitable since mid 2024. We are hiring an additional frontend engineer to support our increasing customer volume, support new products we plan to launch to diversify our revenue streams, and bring our mobile app to feature parity with the web. You will join our engineering team of 14 and work in a dynamic environment where you are frequently writing net new code to support business objectives.

Our tech stack for the front-end is fully hosted on AWS. The web app is in React and we are building a mobile app with React Native, but experience with this specific stack is not necessary for talented candidates. Our preference is candidates who can come in office 4 days a week to our office on the Atlanta Beltline (next to Krog Street Market). VIVA does not provide visa sponsorship, so please have authorization to work in the USA.

Send an introduction to our hiring manger (alexa@viva-finance.com) with a resume and we will be in touch!

Jump | Founding Engineers (Software/AI, Manufacturing) + all roles | Miami, FL | REMOTE (US) until Jan 2027, then ONSITE | Full-time | $140K–$160K + equity | No visa sponsorship | https://jumpscientific.com/careers

Ethan here, founder of Jump.

Machine shops lose jobs because quoting is slow. A part comes in, someone has to read the drawing, figure out how to make it, and price it, and that can take hours. Many shops also can't put customer drawings in the cloud (ITAR, export control, or just customers who say no).

We're building Jump Quote: AI that reads a shop's drawings and drafts quotes in minutes, running on the shop's own computer. We're starting with a small group of founding CNC shops. Long term, we want anyone to be able to make anything, anywhere.

We're hiring founding engineers first (software/AI and manufacturing), but every role is open. If you're exceptional at something a startup needs, apply.

We care about kindness, honesty, ambition and intelligence. We don't care where you went to school or who you've worked for. We care that you have a winning mindset and can learn and ship fast.

How it works: we start now, remote within the US. In January 2027 we're together in person in Miami, and that's when the $140K–$160K + equity package starts. You need to be authorized to work in the US for at least the next 3 years; we can't sponsor visas.

Mozilla | Sr. Staff Software Engineer, Browser (New Products) | REMOTE (US or Canada) | Full-time

Mozilla's New Products group is a small team building new things on top of browser engine technology. We're hiring a hands-on, senior IC to run experiments inside browser engine internals and find out which ideas actually hold up.

What you'd do: design and build experiments in engine subsystems (DOM, layout, accessibility, JS runtime, networking), prototype features that let programs interact with web pages reliably, and measure everything. That means repeatable benchmarks, profiling overhead, and writing up the experiments that didn't work too. You'll use AI tools heavily, but you'll verify what they produce by testing and measuring it.

You likely have: deep experience in at least one browser subsystem, strong C++ or Rust, comfort in a very large codebase, a solid grasp of how the web platform behaves, and a real interest in AI agents and their tooling. Contributions to Gecko, Servo, Blink or WebKit are a big plus.

We are investing in our internal AI transformation with premium accounts for Claude, ChatGPT, and Cursor/Grok. We encourage people to go to AI conferences + use budget to experiment with AI.

We're an intrinsically motivated team that works without ego, is constantly learning, and genuinely cares about our people (5/5 on Glassdoor). We take a lot of pride in our human first culture. AI is cool, but people are cooler.

The roles: We're looking for technically minded builders in all of our roles. You'll own mission-critical parts of the AI product suite end to end, from planning and design through implementation, testing, and shipping. You will be on the front lines of experimenting with new product experiences built with AI. Implementing new tooling + infrastructure to help scale our agents and ensure consistency.
