Ask HN: Who is hiring? (March 2026)

CareMessage is a healthcare technology nonprofit that powers patient communication for 400+ safety-net healthcare organizations — FQHCs, free clinics, and tribal health centers serving low-income and underserved populations.

You will lead the technical direction of our messaging platform, the system behind every SMS, voice call, and multimedia message we deliver. You will design delivery pipelines, build consent management workflows, architect Twilio integration layers, and handle the sharp edges that come with messaging at scale: retry logic, opt-out compliance (TCPA, A2P 10DLC), delivery optimization across carriers, and AI-driven message categorization.

You'll likely thrive here if you:

- Have 5+ years building and scaling backend systems - Are strong in Ruby on Rails and Javascript with solid SQL chops

- Enjoy owning complex features end-to-end, from design through production support

- Think in terms of edge cases, failure modes, and delivery guarantees

- Want to mentor other engineers and shape technical direction

- Care about building infrastructure that has direct impact on patient outcomes

This is a senior role with shared team lead responsibilities. Small, mission-driven team with meaningful ownership. Equitable pay regardless of location.

Nuance Labs is building the first "human foundation model" that understands and expresses human emotion in real-time across speech, facial expression, and body language. We are crossing the "uncanny valley" to create AI interactions that feel truly alive.

Our founding team comes from MIT, UW, and Oxford, with deep experience shipping AI products at Apple and Meta. We are a small, fast-moving team that values in-person collaboration in our Seattle HQ.

*We are looking for*:

Machine Learning Research Engineer: Bridge the gap between research and production. Optimize model inference (TensorRT, vLLM) and build petabyte-scale data pipelines (Ray, Dagster).

Machine Learning Infra Engineer: Own our GPU-backed serving stack, Kubernetes clusters, and orchestration layers.

Systems Engineer (Real-Time Engine): Build our core server-side runtime that synchronizes complex interaction state in real-time. High-concurrency, low-latency systems. Python/Asyncio today, transitioning to Rust.

*Why join*?

Massive ownership in a high-bar, research-heavy environment.

Work on the frontier of multimodal generative AI and real-time graphics.

Competitive equity and the chance to shape a company from the ground up.

We're a VC-funded startup (recently raised $51M Series C) 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-...
