Experienced Software Engineer
Automattic Remote
WordPress doesn’t try to keep its users inside walled gardens, a rare thing in a world that is dangerously moving away from the open web. Instead, WordPress gives them the freedom to build a business website, an online store, or a personal blog – the way they like it. Big sites or small, using the community-run open source project or Automattic’s WordPress.com , vanilla or customized with hundreds of plugins, WordPress users always get to own and control their data, their expression, and their freedom. We’re always looking for talented and experienced engineers worldwide, excited to help Automattic’s product ecosystem, and join our mission to make the web a better place.  What have we worked on recently? AI is at the heart of many new product developments and powers a lot of our day-to-day development workflows. WooCommerce is the most popular and most flexible e-commerce platform on the web. We're working tirelessly on giving you all the control, while keeping...

Senior AI Software Engineer

At Solo, our AI initiatives are helping teams bridge that gap from pilot to production. With our roots in critical cloud infrastructure (gateways, proxies, service mesh) trusted by Fortune 500s, Solo is uniquely positioned to lead AI's next wave. As a nimble startup, we innovate faster, our engineers contribute to high-impact OSS (we're a top CNCF contributor) and solve real scalability challenges.
