Senior Software Engineer

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.     The Opportunity As a Senior Software Engineer, you will help build core parts of the Collectly platform. 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. We are a hybrid company, partly based in Santa Monica, USA and partly remote, spread out around the United States & Europe. 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.
