Protege is looking to solve the biggest unmet need in AI — getting access to the right training data. The process today is time intensive, incredibly expensive, and often ends in failure. We’re building the Protege platform to facilitate the secure, efficient, and privacy-centric exchange of AI training data, starting in the healthcare industry. We’re 4 months old, <10 people, and well funded. We plan to grow to ~15 before the end of the year and are looking for exceptional engineers to build with.

We're a small, late Series A team generating massive datasets of antibody-protein interactions to engineer next-generation therapeutics. Looking for software engineers to lead efforts in drug design and build iterative end-to-end automated discovery workflows. Background in AI/ML required and bioinformatics and protein engineering/design a plus.

We recently launched Lumo, a privacy-friendly ChatGPT alternative, by the makers of Proton Mail & Proton VPN.

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.

Provable is on a mission to make zero-knowledge proof technology accessible to the masses. Most demand for proof generation today exists in the web3 world. Help us expand by making this frontier technology easy to use, reducing fraud in all markets through improved verifiability. We're a Series B company and have raised $228M in funding (Softbank, Kora, a16z). Our engineering team consists of 14 high-agency product-oriented engineers.

Prove AI is an AI management platform that helps organizations centralize and manage their AI models while maintaining strict oversight of data access and usage. Built on distributed ledger technology, Prove AI provides tamper-proof oversight, ensuring organizations can set and enforce guardrails to mitigate risk and optimize AI performance.

Proven is a start-up software company delivering a modern electronic medical record (EMR) to physical therapists. Proven’s Founders and Executive team have decades of experience successfully growing and scaling companies in healthcare. Our mission is to deliver an innovative and impactful solution to healthcare providers leveraging modern technology.

We're building the world's first commercial stellarator fusion power plant. First spin-out from the Max Planck Institute for Plasma Physics, based on Wendelstein 7-X (the largest stellarator ever built), €650M+ raised, teams in Munich, Zurich and Oxford.

Proxybase is building an agentic SOCKS5 proxy network with open-source GUI and CLI, aiming for transparency and fair payouts in the residential proxy market. We provide explicit consent from providers, open-source tooling, and straightforward payouts.

Psiphon is a VPN app used by millions of people to access the open internet in regions where it's restricted. Small team, software that matters. We're building the next-gen client app in Flutter (iOS, Android, macOS, Windows) and need someone who can work across both iOS native and Flutter. Split is roughly 65% Flutter, 35% iOS native (Swift, StoreKit, entitlements, network extensions). You'll have mentorship from a senior iOS specialist for the deeper networking work. Day to day: Feature development in Flutter, iOS platform integration (subscriptions, permissions, App Store), and occasionally going deep into network extensions and packet tunnel providers. Small team (~3-4 core devs), high ownership, low ceremony. Looking for: Strong Swift experience beyond just UIKit/SwiftUI app dev, comfort with the iOS ecosystem (App Store process, provisioning, StoreKit), and willingness to context-switch between Swift and Dart in the same day. Flutter experience is a strong plus but not required if you pick up frameworks quickly. Contact: jobs@psiphon.ca
