Join us to invest in yourself, your career, and the financial world. The role: As a Senior Software Engineer (IC3) on SoFi’s Prism team, you’ll help build Prism, SoFi’s internal AI platform for knowledge work. Prism connects employees with the AI models, business context, and tools they need to solve important problems more effectively. It also creates a continuous learning loop by capturing what works—and what doesn’t—so our workflows improve over time and employees can deliver better results faster. In this role, you will pair hands-on software development with systems thinking. You will take technical ownership over feature delivery and key service components—translating partially defined technical problems into production-grade, highly available microservices. You will collaborate closely with partner teams (such as Autonomous Coding, CI/CD, and product squads), practice operational rigor, and use AI-assisted engineering tools responsibly to raise quality and delivery velocity across our engineering community. What you’ll do: • Design, implement, test, deploy, and operate foundational components of Prism and contribute to the underlying components. • Build and maintain telemetry, usage instrumentation, and reporting pipelines to provide clear visibility into Prism and the learning feedback loop. • Lead technical feature execution for assigned platform work streams, breaking down complex tasks to parallelize implementation with teammates and aligning dependencies with product and engineering managers. • Participate actively in technical design reviews, reasoning through architectural trade-offs (such as latency, fault tolerance, concurrency, and security) and documenting clear technical specifications. • Contribute to team engineering quality by following and refining coding conventions, automated testing patterns, and reusable service templates. • Drive operational excellence by automating test and deployment workflows, participating in on-call service ownership, acting as an incident resolver, and implementing post-incident remediations to prevent recurrence. • Engage directly with internal customers to understand their day-to-day workflows, support adoption of Prism, and incorporate feedback into iterative system improvements. • Mentor early-career engineers through thoughtful code reviews, constructive design feedback, and pair programming to foster continuous team growth. What you’ll need: • Education & Minimum Experience Requirements: Bachelor’s Degree + 2–3 Years of Experience OR Master’s Degree + 2 Years of programming experience in software engineering, computer science, or a related field. • Proven programming proficiency in at least one modern backend language (such as Java, Kotlin, Python, Go, or Scala). • Solid experience building and operating distributed backend services in a microservices or cloud environment, with an understanding of concurrency, fault tolerance, idempotence, and API design. • Practical experience working with relational databases, persistent data stores, and data modeling concepts. • Practical understanding of operational excellence: logging, metrics, distributed tracing, automate
