Senior Backend Engineer

Aurelian

ABOUT AURELIAN Aurelian builds AI tools that help 911 centers handle more with less, so telecommunicators can stay focused on what matters most and communities get the response they need. AVA is a conversational AI agent that answers non-emergency calls; the agent routes, triages, and resolves the calls without any human intervention. By handling administrative calls like noise complaints, lost dogs, and parking inquiries, AVA eliminates hold times and lets call-takers focus their energy on actual emergencies. CORA supports call-takers on the calls that matter most. CORA is an on-screen assistant that delivers real-time SOP checklists, smart reminders, and contextual guidance as an emergency call unfolds, so dispatchers stay calm, consistent, and confident when every second counts. When AVA detects an emergency mid-call, it transfers the caller to a telecommunicator and passes along the caller details, location, incident type, and key statements directly into CORA. The call-taker never starts from scratch. The problem we're solving is serious. The average emergency communications center is 30% understaffed nationwide. Staffing shortages drive burnout and attrition, which makes the shortage worse. Meanwhile, 60-80% of the calls coming in aren't even emergencies at all. Aurelian addresses both sides of that equation: AVA reduces unnecessary call volume, and CORA makes every emergency call more manageable for the people handling it. Aurelian is live in centers across the country, answering thousands of non-emergency calls every day, and is backed by New Enterprise Associates and Y Combinator. Aurelian is growing rapidly; we are hiring people who want to help scale this work and make a real difference in public safety infrastructure for communities across the country. WHY JOIN US Aurelian builds state of the art, multimodal conversational AI systems that help save lives. We work directly with 9-1-1 call centers to modernize emergency response workflows - where reliability, speed, and usability aren’t “nice-to-haves,” they’re mission-critical. We’re hiring a Senior Backend Engineer to help build out the core systems that make up the Aurelian platform. You will solve complex, technical challenges ranging from optimizing latency in realtime AI pipelines, to building robust analytics solutions, and creating flexible solutions to integrate seamlessly with customer systems.   WHAT YOU’LL BE DOING Among other things, you will: * Architect Core Systems: You will help architect core pieces of our voice AI and automation platform for reliability and scalability to help us serve 911 centers across the center in their most critical workflows. * Drive Engineering Excellence: You will raise technical standards, contribute to code review and maintenance processes, and help define what engineering excellence looks like at Aurelian. * Solve Hard Problems: You will solve hard technical problems across a wide range of domains - everything from building effective guardrails to optimizing audio pipeline latency to effectively evaluating AI performance. WHO WE’RE LOOKING FOR * You thrive on autonomy and constantly seek out new challenges. * You have 4+ years of software engineering experience. * You have strong engineering fundamentals, you know your strengths but are always excited to learn new skills. To learn more about what it's like to work at Aurelian, visit our About Us page and follow us on LinkedIn to stay up to date! We encourage you to apply even if you don’t meet every qualification listed above. We believe exceptional people come from many different backgrounds, and we’d rather connect with you than miss the opportunity. Come do the best work of your life and join us in shaping the future of critical technology that truly matters.
