Crusoe | Onsite/Hybrid – SF, Chicago | Climate Tech, Cloud Compute, Distributed Systems, Crypto | https://www.crusoeenergy.com/

Crusoe is on a mission to align the future of computing with the future of the climate.

Data centers consume more than 2% of the world's electricity. We power data centers with stranded energy such as gas flares and underloaded renewables , so for every GPU hour you use on Crusoe Cloud, you're offsetting 0.5kg of CO2e, or approximately 4.4 metric tons over an entire year. The more compute you use, the more CO2 and other greenhouse gasses you offset.

Crusoe Cloud (https://crusoecloud.com/) offers the cleanest and lowest-cost GPU cloud computing solution in the world for workloads including graphical rendering, artificial intelligence research, machine learning, computational biology, therapeutic drug discovery, simulation and more.

Nooks (https://nooks.ai) | Software Engineers (full-stack & backend/applied ML) | Full-time | SF or Remote

Hi, I’m one of the founders of Nooks — we’re trying to re-invent how sales teams work with real-time collaboration and AI.

Nooks is: - A virtual office: you can work from anywhere in the world, but still work with your team and get feedback and coaching like you’re sitting side-by-side. - and an AI co-pilot. We learn how your team works, identify “winning” strategies behaviors, then share them with the whole team during and after calls!

We’re working on fun engineering challenges including complex distributed systems, low-latency algorithms & infrastructure, and modeling sales calls with large language models. You'll also have the chance to make a huge impact on our customers (sales reps who spend 80% of their work day on Nooks.)

Right now we’re a small team (~25 ppl) growing super quickly - doubling revenue every quarter, and recently hit $2M ARR!

Looking for experienced engineers who love tackling difficult product questions and working closely with customers. Excitement about language models, few-shot learning and other recent AI advances is also a plus :)

I’d love to chat: reach me at Email is hidden or apply at the link below: https://nooks.breezy.hr/p/bbc06c1a1bb4-software-engineer

AREO | Remote (EU) | Full-Time | Equity | No Visa Sponsorship Roles: [Senior Backend (Ruby on Rails) Developer, Senior Android Developer]

Hi, my name is Marius and I am the CTO at AREO (https://www.goareo.com - placeholder because we are still in stealth).

We are a young but quickly growing software startup based in Germany that specialises in the development of Augmented Reality (AR) solutions for supermarkets and grocery retail stores.

Our B2B SaaS AR platform helps store employees by providing real-time access to inventory, product information, and POIs. The founders (me and Eike) have more than 10 years of experience with grocery retail and startups.

We are currently looking for seasoned Android and Rails developers with at least 6 years of experience, a knack for crafting clear, well-documented code, a passion for comprehensive testing and an appreciation for beautifully designed products.

For the mobile devs familiarity with AR apps, AR frameworks (AR Foundation, ARCore, ARKit) and AR glasses is a big plus. For both roles being able to understand at least a bit of German would come in handy but is not a must-have :) However, you have to be located in the EU.

Backend Stack: Ruby / Rails (7.x), StimulusJS / Hotwire / Turbo, AlpineJS, Redis, Postgres, Docker, Sentry, DigitalOcean, OpenAPI

Mobile Stack: Kotlin, Room, Jetpack Compose, ARCore, Hilt

We’ll respond to every application.

We're a small team of repeat founders and seasoned operators on a big mission to simplify planet-positive investing and put power in the hands of impact investors at a scale never seen before. The next generation of tools we are building use AI to interact with the world of sustainability data (large language models like ChatGPT). This is a highly specialist crew with a decade or more of relevant experience in the domains of machine learning and climate finance.

Some of the companies we started, (e.g. Secondmind), scaled to 100+ people and millions in revenue, published extensively in key academic journals in machine learning, and won national awards. We also have extensive industry networks, published works, and numerous advisory and working group seats in climate and sustainable finance.

We're looking for people to play a foundational role on this big mission:

- Mid-Senior Backend Engineer (Python)

- (Research) ML Engineer (LLMs)

- Others (opportunistic, including internships)

We have raised our pre-seed round from top European climate-focused investors (Pale Blue Dot & Frontline Ventures) and we have only just publicly announced the company in September! We've always built high-performing teams where everyone is excited to come to work for the team and to make an impact on the mission. Further details are available on our Notion job page (link at the start) and our website!

I'm the CEO and co-founder — if interested, drop me an email (aleksi@) or email our jobs email (jobs@). It'll come to me either way! :)

---

We're a small (23-person) team of repeat founders and seasoned operators building a usage-based revenue platform that helps SaaS companies price however they want. This is a tight-knit and senior crew — most of us have 10-25 years' experience, much of it together.

The last company we started, Second Measure (YC S15), scaled to 70+ people and tens of millions in revenue, received multiple “best places to work” awards, and was ultimately acquired by Bloomberg in a landmark deal.

We're looking for extraordinary builders to play a foundational role in a company designed for scale:

- Billing Platform Engineer (Staff or higher) - Fullstack Engineer (Staff or higher) We're well-funded by top investors (led by First Round Capital), fully distributed, and known for building intentional, inclusive culture. We offer competitive global rates (SF salary + equity), equal pay by level, work flexibility (including a 4-day core schedule), and comprehensive, family-friendly benefits.

I'm Mike, one of the founders— if interested, apply here (https://tryturnstile.com/about) and mention this post.

Railway | Product Engineering, Platform Engineering (Infra), Developer Relations | REMOTE | https://railway.app/careers

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.

If that sounds like you, please apply at railway.app/careers. We have a number of roles, but are prioritizing the following three roles:

+Product Engineer

+Developer Relations

+Infrastructure Engineer

See you soon, and happy shipping.
