Anterior | Software Engineers | NYC | Onsite | Full Time

Anterior is improving the experience of healthcare for everyone. Our agentic orchestration platform makes clinical decisioning frictionless for RNs and MDs.

About You: You have a passion for doing things The Right Way, you believe Less is More, you want to focus on Foundations of system design and architecture (pacelc, consistency guarantees), you care as much about what code you do not write, you’re tired of the hype treadmill and care about the fundamentals. You have battle scars from overengineered and underperforming slop, and you care about writing code that lasts.

- Langs: TS / Python

- Infra: Nix, CDKTF, AWS

We’re hiring from infra to full stack. Come share your proudest firefighting story with us in an interview, bring your GitHub, and let’s see if we’re a good fit!

Dev log: https://xn--xp5a.anterior.app

P.S. We're hosting the NYC Nix meetup on 3/18. Come along to meet the team.

krea.ai | Senior Backend Engineer | San Francisco, CA | ONSITE | https://www.krea.ai

krea does AI research & builds AI tools for image generation, video generation, node-based workflows, LoRA training, and more. Small, mostly in-person team with a view of Alcatraz from the office window. Our users range from hobbyists all the way to professional designers at Apple or architects at firms behind The World Trade Center or Burj Khalifa.

We're looking for senior backend engineers. You'd work across our SvelteKit app (Postgres, Redis, Docker, ClickHouse), Python ML inference on GPU clusters, and k8s clusters across multiple cloud and GPU providers.

Some recent projects:

- building canary deploys with cookie-sticky traffic splitting - implementing durable execution for long-running workflows - designing our public API with OpenAPI docs auto-generated from Zod schemas - implementing enterprise-grade authentication, authorization, and permissions - optimizing ML inference for our hosted image generation models

We care way more about first-principles and core engineering skills rather than specific shenanigans around programming languages or particular tooling—knowing a lot about old UNIX principles is a plus though.

You should be comfortable owning things end-to-end. Experience with GPU infra is a plus. Many of us have some kind of creative background, it helps when building tools for creatives but is not a requirement by any means.

To apply, email d+hn@krea.ai (use the +hn suffix to make sure your email is prioritized!)

FusionAuth | Senior Java Engineer, Technical Support Engineer, Account Executive , Solutions Engineer | Varies between REMOTE (in USA, also in Europe but only for the account exec/solutions engineer positions) and ONSITE in Denver, CO, USA, details in each job desc | Salary ranges listed on job req, but for the Senior Java Engineer it is 140k-180k

At FusionAuth, our mission is to make authentication and authorization simple and secure for every developer building web and mobile applications. We want devs to stop worrying about auth and focus on building something awesome. We also recently acquired a fine-grained authorization company ( https://fusionauth.io/blog/fusionauth-acquires-permify ) and are going to be building in that area as well.

There are a lot of companies in the auth space, but we feel like we have something special:

* a unique deployment model (self-host on-prem or in your cloud or run in our cloud)

* A well designed API first approach; one customer compared our APIs to petrichor

* a mature product (the code base is nine+ years old and we've found and fixed a lot of the sharp edges around core login use cases; but don't worry, there are plenty more features to add)

* our CTO is the founder and still writes code

* a full featured free-as-in-beer version which makes the sales cycle easier; prospects often come in having prototyped an integration already

Our core software is commercial. We open source much of our supporting infrastructure. Technologies and standards that you will work with: modern Java, PostgreSQL, Docker, Kubernetes, MySQL, OAuth, SAML, OIDC.

Learn more, including about benefits and salaries, and apply here: https://fusionauth.io/careers/ ( Click/tap the 'View open positions' orange button. )

We're actively hiring, lots of positions. WEX is an international Fintech company. Most positions are being recruited as on-site roles, must be located near or willing to relocate to one of our locations. It's been a good company to work for, I've been there 7 years.
