Evidation Health | Santa Barbara, SF, San Mateo | Full time and Interns | ONSITE or REMOTE | https://evidation.com/careers/

Evidation runs health studies combining digital data with traditional markers. In addition we run a "why don't you build some good habits" consumer app.

It's an exciting place to be: we work with companies you've heard of to do research you'll hear of. Additionally the company really does only pursue business opportunities that it thinks lead to better health outcomes, so I don't have to worry (much) about all our data being used for advertising or worse. There's a strong culture around privacy, security, and only using data as consented.

As listed on the careers page we have openings on all teams and for all offices, but I'm specifically leading a small team of Rails backend engineers in Santa Barbara who work on "bridge" services that talk to 3rd party APIs, primarily for data ingestion. I'd love to talk to someone with 2+ years of backend experience in or interested in relocating to Santa Barbara. The company in general is very remote friendly and I'd consider adding remote to this team for the right candidate, but more likely at this time a remote Rails engineer would fit in best on one of our other Rails backend teams.

I'm happy to field and route general inquiries about other roles and teams, but again especially looking for a Rails engineer who'd enjoy working on critical data ingestion and related services. jkimmel at evidation dot com

Oso | Software Engineer | New York City (NYC) - Onsite | https://www.osohq.com/

Oso (backed by Sequoia) is making backend infrastructure security not terrible for developers and ops. We provide a normalized and consistent interface to core security controls, like authentication and encryption, and we do so in a way that’s invisible to developers and simple for ops. To get from alpha to a production-ready v1, we need a small number of sharp engineers who want to get involved on the ground floor and who have some combination of experience in and appetite for taking on these kinds of problems:

1. Building an elegant experience for a highly technical end-user, e.g., making it easy and intuitive for an ops engineer to get up and running in <5 mins

2. Low-level distributed systems, e.g., building lightweight proxies that manage requests asynchronously and deal with things like caching and network failures

3. Running an on-path production service, e.g., building a scalable and resilient service layer across multiple regions and cloud providers

We are building the product in Rust, which we think is both a good design choice for our use case and a fun choice for the team. The engineers who join now will not only have a disproportionately large impact on the product, but also on the culture and future of the company. Given the importance of these team members and magnitude of their contribution, they will get a meaningful equity position.

Founding team: Graham Neray (early employee and Chief of Staff at MongoDB) and Sam Scott (PhD in Cryptography).
