NVIDIA | vLLM + SGLang | Deep Learning Inference | Remote (North America preferred)

Hi everyone — I’m Akbar, Senior Manager of Deep Learning Inference Software at NVIDIA. I lead our engineering efforts around vLLM and SGLang, two of the most widely used open-source LLM inference frameworks.

We’re building teams focused on making LLM inference faster, more efficient, and more reliable at scale — from runtime and scheduling optimizations to kernel fusion, distributed serving, and continuous integration across new GPU architectures (Hopper, Blackwell, etc.).

We’re hiring for multiple roles:

• Senior Deep Learning Software Engineer, Inference (https://nvidia.wd5.myworkdayjobs.com/NVIDIAExternalCareerSit...)

• Engineering Manager, Deep Learning Inference (https://nvidia.wd5.myworkdayjobs.com/NVIDIAExternalCareerSit...)

• DL Performance Software Engineer - LLM Inference (https://nvidia.wd5.myworkdayjobs.com/en-US/NVIDIAExternalCar...)

• DL Performance Software Engineer - LLM Inference (https://nvidia.wd5.myworkdayjobs.com/en-US/NVIDIAExternalCar...)

These roles are remote-friendly (North America preferred) and fully focused on upstream open-source development — working directly with the maintainers and the wider AI community.

If you’re excited about large-scale inference, compiler/runtime performance, and pushing GPUs to their limits, we’d love to talk.

Pelairo Inc. | Principal Engineer / Tech Lead | REMOTE (US) | Full-time

At Pelairo we're building the most intuitive and flexible Laboratory Information Management System (LIMS) on the market. "Manage the lab, not the LIMS!"

We're looking for a hands-on Principal Engineer to lead the design and delivery of our backend—built on TypeScript + NestJS—and help our small team iterate quickly with confidence. You'll turn ambiguity into shippable slices, help set technical direction, and raise the bar on reliability, security, and speed.

What you'll do:

    - Own the backend: spend meaningful time writing and reviewing production code.

    - Architecture stewardship: keep the system coherent as we scale questionnaire-driven workflows and FHIR pipelines.

    - Reliability & quality: Establish testing strategy (unit/integration/contract/E2E), migrations, rollouts (feature flags).

    - Observability: Instrument tracing/metrics/logging, build dashboards/alerts; drive incident reviews.
    
    - Raise the engineering bar: define and enforce code review policy, branching model, testing strategy, and CI/CD gates.
    
    - Partner with Product & domain experts: translate healthcare workflows into configurable front-end modules; ensure back-end transforms to valid FHIR in Medplum.

    - 8+ years building production systems, including principal/staff scope in a startup or similar pace.

    - Deep TypeScript + Node.js and expert-level NestJS in production.

    - Track record leading cross-team projects and influencing architecture without heavy process.

    - Product sense and crisp communication; comfortable owning ambiguous problems and shipping quickly with guardrails.

Stack: TypeScript (Next.js and NestJS), Medplum, AWS (Cognito, Fargate)

Visa/relocation: No

How to apply: Email hiring [@] pelairo.com and mention "HN Who's Hiring November 2025". (We know the website needs some work, but the product is our priority right now.)

Railway | Product Design, Customer Success Engineer, Product Eng (full stack)| REMOTE (Worldwide) | https://jobs.ashbyhq.com/Railway?utm_source=DayMzWzJ0P

Tired of trying to beat kube into shape? Does writing YAML to ship code fill you with utter dread? Dream of a future where deploying software is simple, and you don't need an army of infrastructure engineers to build that perfect janky bash script™ to make life easy?

We're Railway, and we think infrastructure can be better. So far we've built out a platform loved by hundreds of thousands of users who simply tell us "Give me Postgres", "Deploy this repo", and we make it happen

Fair warning! The problems are complex: home-rolled hypervisors, cut-above container orchestration, over/under/whateverlay networks, virtio device drivers, edge proxies, IAM that doesn't suck, kitchen sinks - we need to build it and we're looking for likeminded individuals who think this stuff is fun.

Three open roles (apply below!):

krea.ai | Distributed Systems Eng. & Data Engineers | San Francisco (on-site & remote), CA

I'm the cofounder & CTO of Krea (https://www.krea.ai). We are a startup in San Francisco building browser-based AI creative tools to improve the workflows of artists, designers, and professional creatives. Small team (~24); millions of active users; and raised over $83M from top Silicon Valley investment firms.

We're looking for talented engineers who want to tackle hard technical challenges with smart people while building a creative platform that big companies and startups will rely on.

The job:

- Build distributed systems to process massive (billions of files, petabytes), amounts of image, video, and 3D data, solving scaling bottlenecks as you go.

- Learn ML engineering from world-class researchers on a small tight-knit team. You’ll contribute to foundation image, video, and world models from 0 → production, and see them used by millions.

- Play with huge Kubernetes GPU clusters; our main GPU cluster takes up an entire datacenter from our provider.

Tech stack: python, pytorch, k8s, a rotating cast of data tools (e.g. DuckDB, massive relational DBs, PyArrow, etc.)

You should apply if you are an excellent generalist engineer with strong backend experience and an intuition for systems design. Bonus points for experience with dist. systems, k8s, and existing ML or data experience (but not required!). Cool side projects are a green flag.
