Tufalabs | Senior research/engineers | Full Time | Zurich, Onsite | 100-200k CHF | https://tufalabs.ai/ Our current focus is arc-agi 3. We recently hired the top #2 kaggler to join that effort. We are looking for people deeply passionate about AI research. I am steering our work culture towards "live-to-work": If you wouldn't be doing AI research working somewhere else, then it is not a good fit. If you don't find yourself naturally reading about AI papers or doing random AI projects in your free time, then it is not a good fit. We have high expectations and a generous equity structure to match.

Tufalabs is an independent AI research lab in Zurich, focused on high-impact academic-style AI research and large-scale LLM development. We care about compute (currently, 6× DGX B200, 2× NVL72 GB300 incoming). Our mission is to push the frontier of AI science while open-sourcing results and building the engineering muscle to pre- and post-train cutting-edge language models. The ultimate goal is automating AI research, with a strong focus on alignment and safety in the limit.

We can only sponsor visas for people with EU nationality. The position is onsite, fulltime. We are self-funded, from what i call "self-propelled machine learning": I applied ML to cool domains and made returns that way. I can give more details about this privately. If interested, email me at benjamin at tufalabs.ai

Bubblehouse | Fully REMOTE | Full-Time | $200–250k | Principal Engineer

Bubblehouse is a fast-growing custom loyalty platform, tripling the revenue each year. Headquartered in NYC, the entire team is fully remote and spread across the globe. We power loyalty programs for brands like American Girl and Old Spice.

We’re expanding our lean team of extremely experienced developers. Companies are switching from other platforms thanks to the customizations and flexibility that we offer, enabled by our pace and technical excellence, which we intend to keep for years to come.

We run on Golang and use custom data storage on top of local key-value stores, colocating the storage and compute on dedicated hardware servers, and reading data directly from mmap’ed pages of the database. Ever came across HN saying that one can run Twitter on a single machine these days? We’re doing that in production.

Zero lines of React, almost zero third-party dependencies (carefully vetted), every line of JavaScript manually written with respect and understanding of the web platform. We render HTML server-side like it’s 2005.

Looking for:

1. Top to bottom understanding of the software stack, from the modern-ish web platform to CPU caches.

2. Thinking and problem solving outside the box. (We don’t _always_ go for unconventional solutions, but we do it often enough to require a person who can do justice considering the entire problem space at every step.)

3. Demonstrated ability and hunger to learn new things quickly. (Every month we’re doing things we have never done before.)

4. Broad experience across multiple programming paradigms, platforms and software stacks.

5. Demonstrated care for the software craftsmanship (which can take many forms).

6. Great spoken English, and ability to communicate 9am to noon in New York time zone.

We give you a literally fast-paced environment (with features delivered in days) where you need to solve very challenging problems with practical advanced technology, take on entrenched market leaders, and help entrepreneurs across small and large businesses delight their fans.

Send a plain text cover letter to andrey+hiring@bubblehouse.com. Help us see how you stand out. Summarize your experience. Link to 1–5 impressive things you’ve built and proud of, link to where we can see some of your code, include your portfolio/CV, describe the platforms and stacks you’re an expert in. How did you start programming? What are you most passionate about in technology? What are the most interesting or weird things you’ve done? What are your strongest held professional opinions? Please make your email easy to read, we’ll appreciate that.

(If you have applied before, no need to re-apply, we’ll reach out.)

Numeral | Software Engineer (full-stack, AI team) | Hybrid (NYC) | $175k - $300k

We build sales tax compliance software so companies can focus on their product instead of taxes. We’re one of the fastest-growing players in the space, taking share from incumbents like Avalara.

We’re a small, high-ownership team. My team in particular is applying AI (agents + workflows) to automate and dramatically reduce operational overhead.

What you’ll do:

- Build product + AI infra across the stack

- Work on AI-driven systems (agents, orchestration, internal tooling)

- Ship quickly with real user impact, both internally and externally

If interested, can send resume directly to jerry@numeralhq.com and I'll fast track!

Spacelift | Remote (Europe) | Full-time | Senior Software Engineer | $80k-$110k+ (can go higher)

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-...

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

Against Malaria Foundation | Senior Software Engineer | Remote (UK) | Full Time

The AMF works to fight malaria in an extremely cost effective way with insecticide treated bed-nets. Every year hundreds of millions of people will be infected with malaria, and half a million of them will die, with many more being debilitated or disabled. Independent charity evaluators, such as GiveWell, have ranked the AMF as one of the most cost-effective charities in the world for over a decade, due to our long and well-studied track record preventing hundreds of millions of cases of malaria.

Our tech team is just a couple people, and all-remote. Our software is essential to the charity work we do; it is one of the ways we stand out among other charities, by allowing us to automate, analyze, and validate our work in novel ways. Our tech stack includes C# .NET, Blazor, and Python.

If you are a senior SWE in the UK who is interested in making a difference, please reach out to me by email at my first name at againstmalaria.com

Quadrature | Quant Dev | London, New York, Singapore | Full-Time | Onsite

We’re Quadrature, a technology company in the algo trading space. We use advanced machine learning on large amounts of data to predict trends in financial markets. More at https://quadrature.ai.

What makes us different:

- ~250 people, no traders — our systems trade autonomously.

- Single PnL.

- We don’t separate “quant researchers” from “developers” — everyone codes to a high level and has the opportunity to do research.

- Mission-driven: our climate foundation (https://www.qc.foundation/) has made significant divestment commitments over recent years. For many of us, it's why we're here.

We’re hiring Quant Developers — a generalist team of engineers and researchers who own both the research pipeline and software infrastructure across the entire business. Stack is Rust, Python and C++. We want sharp, collaborative people with no big egos.

Stackable | Product Engineer - Web & UI | Remote (Germany/UK) | ~20 people | Full or part-time

We build an open source data platform on Kubernetes. The product (Stackable Data Platform - SDP) bundles 12+ open source data tools (Trino, Apache Kafka, Apache Airflow, Apache Superset, etc.) and makes them work together. Right now everything is Infrastructure-as-Code only. We need someone to build a UI layer on top.

No mockups, no Figma, no product roadmap waiting for you I'm afraid, just a bunch of ideas :) We're all backend people and need someone to own this end to end. Play around with our product stack, figure out what customers actually need, build it.

Stack (because we got started without you...): Svelte/SvelteKit, TypeScript, TailwindCSS. SDP itself is Rust, Java, Python on K8s. Three releases a year. Not SaaS. Quality matters.

100% remote, Germany (UK possible) only, no other countries, sorry. No Scrum, minimal meetings. Interview process is usually just two conversations. The position isn't on our homepage yet as I'm on vacation. Send a mail to recruiting@stackable.tech and I'll get back to you next week. Please mention HN in your mail. My personal mail is also in my HN profile. I'm the Co-founder and CTO.

New Lantern | https://newlantern.ai | Software engineers (backend and generalist product engineers, founding security engineer) | Full time in San Francisco, CA (ONSITE)

New Lantern is building an AI radiology resident—think Cursor for radiologists. Our application integrates the three software tools radiologists use all day [1], together with AI, to create a platform that saves radiologists toil and lets them focus on reading images and finding disease.

We are a series A startup with ~15 engineers (~30 total staff), have live customers generating revenue, several years of runway, and are backed by Benchmark, Anthropic, and other great investors.

We're hiring for several engineering roles. You'll work directly with our founder/CEO, our staff radiologists, and our end users to build a product that radiologists rely on daily. You'll have real ownership and autonomy, and ship meaningful work frequently.

I'm Steve, New Lantern's Head of Engineering. If you're interested or want to learn more, shoot me a note at (my HN username)@newlantern.ai. I've already hired one engineer from HN this year and interviewed many more!

Kinelo | kinelo.com | Product Engineering (Backend+AI focus) | San Francisco | Onsite (with flexibility)

We are hiring two Product Engineers to join us in our newly opened office in SF. We're small and early and you'll help shape team culture.

Kinelo solves "context myopia": autonomous and semi-autonomous AI agents don't know what they don't know, so they can't search or find the background information required to accomplish tasks accurately and effectively. The result looks like slop but it's not due to model performance, more due to workflow integration. From there, we're rapidly moving into organizing humans together with autonomous "AI coworkers" into workflows that span both. Our goal is to change how organizations are run and structured.

Our #1 hiring criteria for this position is immense software wisdom, the kind not yet encoded in the weights of an LLM. We are not looking for artisans to meticulously craft single lines of code. We're looking for software engineers excited to use the leverage that AI offers for code production to permit focus on higher order technical architecture, product requirements, and user needs.

We're looking for enough experience that indicates accumulated wisdom in shipping and maintaining reliable, scalable software, solid CS fundamentals, experience taking products from 0 to 1, and versatility.

Our current tech stack includes TypeScript, a managed container service, Postgres, and Redis. But we are adaptive and you should be too. We highly value software engineering and computer science fundamentals and experience with other languages like Go, C++, Python is valued.

Competitive salary, meaningful (~first batch of hires) equity, founder previously exited to Apple, strong fundraising history (~$10m).

Please email us at jobs@kinelo.com. If you want to stand out, tell us how you think the job of a software engineer is changing. There's also a full JD here: https://job-boards.greenhouse.io/kinelo/jobs/4205846009
