Proton VPN (https://protonvpn.com/) | Senior Performance Engineer | Barcelona, Spain or Geneva, Switzerland | ONSITE

Proton VPN enables millions of people to connect securely and privately, even in places where the internet is restricted or unreliable. Delivering that experience means our service must perform flawlessly under highly variable, real-world conditions.

We are looking for a Senior Performance Engineer to lead our efforts in making Proton VPN the fastest, most resilient, and most reliable VPN service in the world.

You will define and drive the measurement, analysis, and optimization of Proton VPN’s end-to-end performance, across clients, platforms, and global infrastructure. You’ll help ensure that every connection is fast, stable, and private, regardless of where the user is or what network they’re on.

We're looking for candidates with experience in system-level development (e.g. C or C++ or Rust), and network engineering (experience working with UDP/TCP and VPN protocols).

Apply at: https://job-boards.eu.greenhouse.io/proton/jobs/4725157101 (see also: https://proton.me/careers)

Sentinel Defense Technologies | Remote (Global) | Equity → Pre-Seed in 6-10 Weeks

We are building an AI-powered civilian protection platform — real-time threat intelligence for non-combatants in conflict zones. Think Waze for airstrikes. Multi-model AI pipeline (Gemini) ingests OSINT, verifies it through gated analysis, and pushes geolocated alerts to offline-first mobile clients. People die when information is late or wrong — we are solving both problems.

We are currently unfunded, operating on sweat equity. Pre-seed is 6-10 weeks out. This is not a side project — we have a working system, a pipeline of 39 vetted applicants, and a founder who has been shipping code daily for months. But I will not sugarcoat it: right now, this is nights-and-weekends until funding closes.

*We need two people:*

*1. Systems Architect / Full Stack Dev* You see the whole board. You think in pipelines, failure modes, and deployment constraints — not just endpoints. You will own the technical architecture of a system where a bug isn't a bad UX, it's a missed warning. Python/Django, MongoDB, LLMs (Gemini/Vertex AI). Bonus: Flutter, OSINT, geospatial.

*2. Implementation Partner / Full Stack Dev* You ship. Relentlessly. You take a spec and it's done by morning. You don't wait for perfect — you build, test, push, iterate. Same stack: Python/Django, MongoDB. You will be the person who turns architecture into working product at startup speed.

Both roles require exceptional drive. This is a founding team — not a job listing.

*Compensation (No BS):* - *Now:* Sweat equity only. You're building your stake. - *Pre-Seed (6-10 weeks):* $3,000/month + equity per contributor. - *Seed (6-12 months):* 75% market salary + equity. Increases from there.

If you need full salary today, this is not for you. If you want to build something that actually matters and you're willing to bet on yourself for 6-10 weeks to get there — keep reading.

*Stack:* Python, Django 4.1, MongoDB, Flutter, Vertex AI (Gemini), Docker, AWS.

*Apply:* PeterJFrancoIII@gmail.com — Send your resume or GitHub and tell me what you'd ship in your first week.

Blueberry Pediatrics | Full-stack Senior or Staff Engineer | REMOTE (US only)

American healthcare is seldom affordable, accessible, or high-quality. We are fixing this for pediatrics. Blueberry is the most affordable option amongst our competitors. We practice the highest quality pediatric telemedicine, as evidenced by our exclusive hiring of board-certified pediatricians and the usage of at-home medical kits. And, we’re accessible 24 hours a day.

Our success is shown in the lives we save, the costs we save our insurers, and our exploding B2B and D2C business.

As you can imagine, pulling off affordable high-quality healthcare is a challenge. It requires a lot of engineering ingenuity, a C-suite aligned with positive patient outcomes above short-term profits, and a great product team.

We use Django, Hotwire Turbo (an HTMX-like framework), Pytorch, Sklearn, and Flutter. Experience in these technologies helps, but what’s more important is general full-stack knowledge, curiosity, and a strong work ethic.

Di Rezze Family Office | AI-Native Technical Operations Lead | Miami, FL (ONSITE) | $130K-$200K + Early Equity | Full-Time

We're building an AI-native clinical data platform from the ground up, not a legacy system with AI bolted on. AI is core to the architecture, the development workflow, and the product itself. Fully funded by a private family office, no outside capital needed, no fundraising runway concerns. We're assembling the founding team now.

We're building a founding team to revolutionize healthcare in the United States, and we're hiring a technical operations lead. Best analogy: studio engineer to a recording artist. You own the environment so engineering leadership stays on high-leverage product work. That means CI/CD, QA, testing infrastructure, compliance documentation, and 30-40% independent feature development. Ground-floor equity in a company that's pre-revenue by choice, not by circumstance.

Hard requirement: you are already shipping software with AI coding tools daily (Claude Code, Cursor, Copilot, or similar). Not curious about AI. Not experimenting. Actively building and deploying with it. If you can't show us something you built with AI tools in the last 60 days, this isn't the right fit. Stack: React/Next.js, Python, PostgreSQL, Docker, AWS. But we care more about polyglot instincts than any single framework.

What we're looking for:

3-7 years full-stack experience Strong QA discipline (you write tests because you want to, not because someone made you) DevOps comfort: Docker, CI/CD pipelines, cloud infrastructure Self-directed. We don't micromanage and don't plan to start. Must be US-based or already have US work authorization. We do not sponsor visas.

What you get:

Meaningful early-stage equity (not a token option grant)

Direct access to founders and decision-makers, no layers

A say in the technical architecture from day one

Relocation to Miami fully covered

Health, dental, vision

Interview process: 15-min screen (show us your AI-built work) > take-home exercise > 2-hour paid working session > culture fit conversation.

Email: jpd@direzzefamilyoffice.com, subject line "HN March 2026" so I can find you.

Softmax | softmax.com | San Francisco (onsite) | Full-time

THE MOST IMPORTANT UNSOLVED PROBLEM IN AI IS THE MOST POWERFUL OF ALL CAPABILITIES: ALIGNMENT.

Hi, I'm Emmett. You may know me as the founder of Twitch (YC S05), and as the (extremely) interim CEO of OpenAI.

I believe the question of how AI systems learn to understand themselves and others is one of the most consequential technical problems of our time. If we get it right, the agents we build today will become our friends and collaborators tomorrow. And the infrastructure required to train agents that are good at working in teams and societies will be extraordinarily valuable.

Softmax is building large-scale multi-agent, multi-policy environments that will benchmark AI agents – both our own and others – on their capacity for theory of mind, adaptive goal setting, and teamwork. We’re looking for the engineers who will make that possible.

The work is unusually hard. The problems are ambiguous and challenging. High autonomy, high expectations. You'll work directly with me and the rest of our small but mighty team.

If this sounds exciting, I’m looking forward to meeting you. E
