Location: 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 the platform fast and stable. Gutenberg is a new block-level editor for WordPress with clean abstractions for users, too, not just developers. Tumblr is a microblogging social network where users create, share, and follow what they love. To view more of our recent work, check out our longer product list on Automattic.com . How do we work? We’re kind to each other and our users – we build a positive, supportive, and inclusive culture of cohesive teams focused on building useful products for our customers. We work as a global and distributed workforce resulting in a unique way of working built around our creed . We offer flexible work arrangements allowing our team members to work when they feel best. We open-source! We’re cool with open-sourcing everything except passwords, or secret keys. We ship often, deploying many times daily with the help of peer code review, continuous integration, and our global workforce in over 70 countries. We welcome collaboration, and you can be involved in any discussion across our many communication channels. We encourage you to learn and develop and we support you with what you need – covering expenses, easy internal mobility, coaching. Enough about us, let‘s talk more about you. Working at Automattic might be a good fit if: You care and often obsess over the quality and the details of your work. Debugging any problem is a fun challenge and not a chore. Understanding the layers of abstraction below and above your work isn't something extra, but how you operate. You have production experience with several programming languages, frameworks, and paradigms. We mostly use PHP and JavaScript at Automattic, we expect you to be comfortable with the idea of becoming an expert in these languages, even if being one isn't a requirement to apply. In your mind abstraction is associated as much with cost as it is with value. You have experience working at scale – it can be on the backend and performance side, or via the complexity of interacting with a multi-million diverse userbase. Are open and able to travel 3-4 weeks per year to meet up with your teammates in person. These are exciting times at Automattic and you’ll have a unique opportunity to shape the future of our products. Join us! We look forward to hearing from you.

Location: Austin, Texas Workplace: remote About Collectly Collectly is a fast-growing healthcare technology company transforming revenue cycle management (RCM) through AI-driven automation. Millions of patients navigate inefficient billing systems every day, while providers face delayed payments, rising administrative burden, and operational complexity.   Collectly applies artificial intelligence to automate workflows, accelerate cash flow, and modernize the patient financial experience; enabling healthcare organizations to operate more efficiently and focus on delivering care.   There could not be a hotter space to play in.  Healthcare is a $4.9T industry and is adopting AI technology at 2.2x the rate of the rest of the economy.  RCM is at the heart of this transformation as it has a clear and demonstrable ROI to our customers. We’re a hybrid team, with roots in Santa Monica and teammates distributed across the U.S. and Europe.     The Opportunity As a Senior Software Engineer, you’ll join a small, talented team building Collectly’s core pre-service product. Our stack is Python-first, and we’re looking for engineers who are comfortable designing and evolving backend systems in Python. Experience with React is a strong plus, especially if you enjoy working across the stack to deliver polished, user-facing experiences. You'll collaborate closely with the founder, engineering leadership, product managers, designers, and fellow engineers to ship high-quality, impactful features for healthcare providers and patients alike. Key Responsibilities Work closely with the founder, product managers, designers, and engineers to design and build a high-impact product. Build and ship critical features with intent, strong attention to detail, and a focus on long-term maintainability and scalability. Own features end to end, from shaping requirements and implementation to testing, observability, deployment, and iteration in production. Contribute to and help shape our engineering culture as the team grows. Required Qualifications You have 6+ years of experience building and operating complex web applications in production environments. You have strong experience building backend systems, ideally in Python using frameworks like FastAPI or Flask. You’re comfortable working across the stack. Experience with React is a strong plus, especially if you enjoy building thoughtful, user-facing experiences. You understand that velocity and quality aren’t opposites. When well done, they’re multiplicative. You think in terms of outcomes, not just implementations. You care about solving real customer problems, even when the requirements aren’t perfectly defined. You prefer pragmatic, well-reasoned solutions over theoretical perfection, and you know when “good and shipped” beats “perfect and late. You’re comfortable owning features end-to-end, from vague ideas to production impact and iteration. You reside in the United States How We Work: Start with a 1–2 week onboarding onsite in Los Angeles/Santa Monica with our CTO — travel and accommodations fully covered.
