Senior Systems Engineer

ABOUT SORIS We are a stealth technology company building at the intersection of foundational AI and systems design for real-world impact. Our mission is bold: to reimagine one of the largest and most entrenched industries on the planet, creating an entirely new model that is faster, fairer, and fundamentally better for humanity. Unlike wrapper companies or point solutions, we are building a full-stack AI platform from the ground up; one that is agentic, vertically integrated, and designed for scale. This gives us the rare ability to solve problems others can’t touch, operating with orders-of-magnitude more efficiency than legacy systems. Our founding team has scaled category-defining companies in frontier tech, aerospace, mobility, and AI. We’ve led organizations from zero to multibillion-dollar valuations, pioneered new industries, and built products that reshaped how people live and move. Now we’re assembling a small, fiercely talented team to take on our most ambitious challenge yet. Joining us means working on cutting-edge research with direct application, where your code doesn’t sit in a lab, it changes lives. You’ll be part of an environment that values intellectual rigor, creative rebellion, and the courage to build what others say is impossible. This is a once-in-a-generation opportunity to help design and deploy the infrastructure of the future. We’ve raised capital in record time, and are scaling our foundational team now. If you’re motivated by hard problems, high impact, and the chance to leave a legacy, we’d love to talk. THE ROLE We’re looking for a Senior Software Engineer with backend engineering expertise to join our Engineering team. You’ll work alongside the CTO and other engineers to build Soris’ first MVP. You will be doing foundational work such as building our core APIs that interact with our agentic systems, building a deployment infrastructure that allows rapid experimentation, architecting our RAG pipelines and architecture, and setting best practices for the entire engineering organization. This is a ground-floor opportunity where your work will directly shape the platform, culture, and impact of Soris. Candidates with a good fit for this role: * Want to ship fast, iterate, and own outcomes. * Thrive in ambiguity, asking questions and solving problems across the stack. * Believe in building systems that are secure, transparent, and human-friendly. WHAT YOU’LL DO * Design and build core backend systems and APIs that power our Soris products. * Develop scalable data pipelines and storage systems for high-availability agentic systems. * Collaborate with the product division to integrate agentic workflows into the core platform. * Work closely with early stakeholders to deliver solutions that solve real pain points. * Contribute across the product lifecycle: architecture, implementation, testing, deployment, and monitoring. REQUIREMENTS * 5+ years of experience building backend services from end-to-end. * Strong proficiency in Python, Go, Rust, or a similar language. * Demonstrated expertise in system design and development. * Experience with databases (SQL/NoSQL), cloud infrastructure (AWS/Azure/GCP), and CI/CD pipelines (GitHub actions). * Experience with Infrastructure-as-Code (Terraform is a huge plus!). NICE-TO-HAVES * Strong experience building or integrating AI agents into production systems. * Background in highly regulated industries (HIPAA, SOC2, HITRUST, PCI, etc.). * Experience with payment rails (Stripe, SVB, Square etc.). * Experience optimizing payment flows, financial reconciliation, or compliance-heavy data pipelines. * Contributions to early-stage startups or small teams where wearing multiple hats was key. * Knowledge of security and compliance best practices for handling sensitive customer and financial data. ENGINEERING CULTURE AT SORIS Our values guide how we work: * Extreme Ownership: We own outcomes, not just code. At Soris, we never say “that’s not my job”. * Always Be Curious: Ask questions. Explore new ways. * Go Farther Together: Collaboration beats silos. WHY JOIN US? * Competitive compensation package, including salary and equity. * Benefits include employer-covered health insurance for you, your spouse, and partially for children * Be part of an engineering team with massive influence on product, culture, and direction. * Work with cutting-edge AI agents and modern tech stacks. APPLY If you’re excited about transforming big antiquated industries, shipping fast, and working with a driven, world-class team, then we’d love to hear from you!
