We're a VC-funded startup building an infrastructure orchestrator and collaborative management platform for Infrastructure-as-Code – from OpenTofu, Terraform, Terragrunt, CloudFormation, Pulumi, Kubernetes, to Ansible.
On the backend we're using 100% Go with AWS primitives. We're looking for backend developers who like doing DevOps'y stuff sometimes (because in a way it's the spirit of our company), or have experience with the cloud native ecosystem. Ideally you'd have experience working with an IaC tool, i.e. Terraform, Pulumi, Ansible, CloudFormation, Kubernetes, or SaltStack.
Overall we have a deeply technical product, trying to build something customers love to use, and have a lot of happy and satisfied customers. We promise interesting work, the ability to open source parts of the project which don't give us a business advantage, as well as healthy working hours.
If that sounds like fun to you, please apply at https://careers.spacelift.io/jobs/3006934-software-engineer-...
You can find out more about the product we're building at https://spacelift.io and also see our engineering blog for a few technical blog posts of ours: https://spacelift.io/blog/engineering
Ascertain is a healthcare AI startup backed by Northwell (New York's largest health system) and Deerfield. We're a small team automating the painful admin work that clogs up the U.S. healthcare system — things like prior authorizations, discharge planning, and insurance claims. Our goal is simple: give time back to clinicians so they can focus on patient care, not paperwork.
We've found early product-market fit and are growing the team thoughtfully. We're hiring senior engineers across the stack: backend, frontend, and AI/LLM. We're NYC-based and hybrid (most of us come in ~3 days/week). We're not counting badge swipes — we just want teammates who want to be in the room with us often enough to build trust, have fun, and work on hard problems together!
What we're building:
* A general-purpose automation platform for healthcare ops, powered by LLMs
* A system that reads unstructured documents, fills out payer forms, and explains rejections
* Tools to automate patient discharge planning in hospitals
* A foundation for making AI in healthcare safe, observable, and human-in-the-loop
What we're looking for:
* AI Engineer — experience productionizing LLM apps (agents, RAG, embeddings); solid Python; knows how to build ML systems that ship
* Backend Engineer — strong Python/FastAPI; infra-savvy (K8s, Terraform, Docker); thoughtful about API design and scalability
* Frontend Engineer — React/TypeScript expert who's opinionated about UX and happy to dip into backend when needed
More importantly, we're looking for engineers who like open-ended, ambiguous challenges, and want to work with a tight-knit, high-trust team to solve real-world problems.
I'm a Principal Engineer here — if anything here resonates, drop me a line at john@ascertain.com or apply at our job board using https://lnkd.in/e5ZnGuqH!
Edlink is a small, high-performing team building the data infrastructure that powers edtech. Our API helps 60M+ students and educators access the software they need to teach and learn. We solve hard problems — messy school data, ancient SIS platforms, massive scale — and we do it without red tape, meetings about meetings, or fluff.
We’re 23 people, all in on building fast, owning our work, and helping each other grow. We believe in high trust, deep work, strong opinions (held loosely), and building great tools that actually help people. No micromanagement. No bureaucracy. Just a team of sharp, kind engineers shipping great code and pushing each other to improve.
The role: You’ll work across our stack (TypeScript, Node.js, Postgres, Kubernetes, Vue 2/3), building powerful APIs and clean UIs that help integrate thousands of school systems. You’ll also work directly with developer clients who use our API — think Stripe for edtech.
Perks: Equity from day one, unlimited PTO, free downtown parking, paid parental leave, relocation support, and weekly team lunches.
We’re in-person in Austin because we believe startups build better products — and have more fun — when they work side by side.

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.
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 app to petrichor
* a relatively mature product (the code base is over eight years old and we've found and fixed a lot of the sharp edges around core login use cases; however there are plenty more features to add)
* founder-led; the CEO is an engineer who still writes code
* a full featured free-as-in-beer version that makes the sales cycle easier; prospects often come in having prototyped an integration already
If you are passionate about technology and want to join a company moving the industry forward, FusionAuth might be a great fit for you. As mentioned, our core software is commercial with a "free as in beer" version. We also open source much of our supporting infrastructure.
We are profitable but raised a round in 2023 to accelerate our growth (more on that here: https://fusionauth.io/blog/fusionauth-funding ).
Technologies and standards that we use or implement: Modern Java, MySQL, PostgreSQL, Docker, Kubernetes, OAuth, SAML, OIDC.

* Senior Software Engineer, iOS - Objective-C, Rust, Swift, and smaller amounts of other languages. Note that we're not building apps. It's about taking things apart, seeing what makes them tick, and figuring out how to get at the bits we need without negatively impacting the app experience. (Or using any private APIs!) It's part reverse engineering, part systems programming, and part library development. Low-level knowledge of Swift and SwiftUI would be particularly helpful. - $176,000 to $207,500 (US) - https://www.fullstory.com/careers/jobs/ab3f8ecb-ee1f-4431-a0...

At Tandem Health we're building a clinician copilot to allow clinicians to focus on care rather than administration. We’re building, launching and iterating quickly, and already have >500 organizations using our product.
Our core product listens in to the patient-clinician encounter to generate medical records, allowing clinicians to save 5-10 minutes per patient. No longer do clinicians have to catch up on administration after hours. Some even tell us that their partners notice they're much more relaxed after starting to use our product, and we couldn't be happier :)
