#156The 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

#158We'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

#159We build an AI system that builds software for complex construction & infrastructure megaprojects to sell things currently only sold by service providers. To do this, we both do whatever it takes to solve complex projects' needs AND build the system that automates ourselves out of it. We just raised our seed round (25m$ valuation) and currently have 4 people, looking to hire 6-10 total this year.
== Platform Engineer Build the system that takes our jobs. Algorithms, infrastructure, shared components, agents, and internal tooling - across the full stack. Our platform engineers build everything from our custom meeting integration to AI coding agent harnesses, sandbox environments, complex shared app features and more.
== Customer Delivery Lead / Forward Deployed Engineer Help build the AI systems that run megaprojects. We’re looking for a customer-obsessed generalist who can understand complex problems and ship solutions - part product designer, part delivery lead, part AI wrangler. In this role you deploy with customers, build software that solves their problems and do whatever it takes to maximally learn about the way they run their complex projects.
