Also check out Nava-- we're a part of the original team and continuing to improve Healthcare.gov and work on other projects, and we're actively hiring for software engineers in SF and DC. See profile for details!
Binti's main SaaS web product is a conventional monolithic Rails/Postgres app that delivers value in heaps and heaps, and remains super fun to hack on. We're building the monolith up higher and higher, and looking forward to soon chipping off a service or two (perhaps in Elixir?). Specific engineering roles we have open are for someone that is highly-opinionated on the front-end stack/practices, a security specialist, and a UX/a11y specialist. We're using Kubernetes for cluster management.
Interesting. Thanks for the info. Is no recent rails experience an issue? I have django experience (years worth) but anything recent with rails (nothing after rails 2).
