Ask HN: Who is hiring? (March 2020)

Tray.io | London | Backend Engineer (Scala/Java) / Security Engineer / Frontend Engineer | Full-time | Onsite | https://tray.io

Tray is a visual programming platform. It’s a low-code user experience that allows anyone to build business logic that precisely defines how data flows through their organisation.

We’re a well-funded startup with a team in San Francisco and 100+ in our London Engineering HQ. We have secured a huge Series C in November this year, at over 8.5x the valuation of our Series A in March 2018; we’ve worked hard on creating a fantastic support layer for our technical teams and now we’re expanding. We’re small (approaching medium sized) and dynamic, very open to new ideas and the work you do now will have a big impact on shaping how we grow our team and our product.

We aim to pick the right tool for the job, and currently use: Typescript, React, Redux, GraphQL, and our toolchain includes Webpack and PostCSS. On the backend, our APIs are built in Scala, with Go and Java powering some of our custom services.

We are excited by people who want to constantly innovate; borrow from other industries, experiment with new tools and pool their knowledge with other solution seekers; people who have shipped entire projects with ownership and autonomy; people who take pride in what gets built, all the whilst balancing day-to-day pragmatism with building for the future.

Stateless | Boulder, CO | Onsite | stateless.net

At Stateless we are building something special. Not just in terms of a disruptive technology but also in terms of culture. A culture were people authentically personify our organizational values. Supportive. Sincere. Studious. Striving. Stateless.

Stateless is on a mission to reinvent network connectivity. Central to that was our initial innovation, where we demonstrated an ability to efficiently decouple state from processing in network functions—a task deemed infeasible in high-performance networking systems, but in doing so, we have opened the door for fundamentally changing how networks are built. Now, we are building the product around that vision. VCs have backed us, and early adopters have validated the business opportunity.

We are hiring for a variety of roles: from C++, Python, and Kotlin developers to DevOps, sales and support engineers.
