Companies like AWS, Stripe, and Twilio have shown that if a technology isn't core to your value proposition, you should offload it. Still, every engineering team builds and rebuilds one piece: authorization , how you control who has access to what in your app. We intend to change that.
We see a world where developers never roll their own authorization again, and instead say, "Just use Oso" – the same way you might say, "Oh, you should just use Postgres for that." In doing so, we're creating the $25B+ authorization market.
We have the lead – in traction, capital, and team.
Traction : Oso is used by thousands of companies from startups to the Fortune 500, like Wayfair, Arc, Intercom, Visa, Oxide, and Codecademy.
Capital : We're the best-capitalized, with 4+ years of runway from the world’s best investors, including Sequoia, Felicis, and infrastructure entrepreneurs like Olivier Pomel (Founder, Datadog), Dev Ittycheria (CEO, MongoDB), Arman Dadgar (Founder, Hashicorp), Edith Harbaugh (Founder, LaunchDarkly), Guy Podjarny (Founder, Snyk), Paul Copplestone, (Founder, Supabase), Christina Cacioppo (Founder, Vanta), and Calvin French-Owen (Founder, Segment).
Team : We've spent 3+ years going deep on the domain. We've met with thousands of engineering teams and know more about this problem than anyone. And we have two of the best developer go-to-market leaders on earth who have done it before at MongoDB and Snyk.
We're at an inflection point. What it takes to get from where we are today to a world where developers say “Just use Oso” is going to be different. And we see that.
The opportunity is for you to join at this inflection point, in a role that’s bigger and different than usual.
Experiment, design, and build UIs, flows, features, and layers of abstraction that decrease the amount of work our users have to do. Lots of devex
Expand use case coverage of our core authorization service
Build and operate infrastructure for our highly available and low latency cloud service
Plus, help build a company and community from the ground up by wearing other hats, including:
Writing documentation and blog posts to excite and support new users
Engaging with users through support channels (e.g., Slack) to help them with their problems
Here are examples of things we've worked on:
Built a visual policy builder for our declarative policy language, Polar
Built an interactive debugger, called Explain, to help users understand why authorization requests succeed or fail
Implemented incremental forward chaining to cache authorization responses for deeply nested recursive queries
You're ambitious. You want to win big. You can't stand to be around anything but execution at the highest level. You have an inner motor to move fast.
You're an owner. You are accountable to results over the process. You see yourself not just as an engineer, but also as an owner of the company.
You're resilient. Building a startup is not for the faint of heart. You see the challenges as not just normal, but actually desirable.
You want to grow, and help others grow. You self-reflect often. You give feedback, and you seek it out.
You prioritize the customer above all else. You want to understand our users' world and prioritize solving their authorization problems above everything else.
You have 4+ years of experience as a software engineer
You have worked at a startup or in a similar environment
You have worked on developer experience and/or user experience
You can program at different levels of the stack – i.e., frontend and backend, web app to lower level systems
The starting salary for this role is between $100,000-$500,000/year plus equity. Your exact offer will vary based on a number of factors including experience level, skillset, market location, and balancing internal equity relative to peers at the company.
