Senior Software Engineer, Payments

The role

You will design, build and operate core systems for Nova, a banking and payments network for private markets. The work covers the ledger, bank and payment integrations for ACH and wires, KYC, and secure PII handling. You will own parts of these systems from design through on-call operation.

What you will do

• Design, build and operate core Foundations systems: the ledger, bank and payment integrations, KYC, and secure PII handling
• Take problems from design through rollout and on-call operation
• Model complex financial and identity domains in relational data and build service contracts and APIs for Product teams
• Build for correctness, auditability, security and reliability; help catch predictable failures early
• Improve the team's work through code reviews, design feedback and mentoring other engineers
• Work with Product teams and Compliance/Risk to keep the platform coherent across team boundaries

Required qualifications

• 5+ years building backend or full-stack systems, including backend services that other teams or users depend on
• Senior-level impact: you have owned significant systems or features from an ambiguous problem through launch and operation
• Experience with financial systems, payments, ledgers, or banking/KYC integrations, or a strong record in another domain where correctness and reliability are non-negotiable
• Strong data-modeling skills in relational databases
• Comfort working in a Ruby on Rails environment, or evidence you will ramp quickly
• Comfort with service-oriented systems, real bank and payment-rail integrations, and workflow orchestration
• Comfort working in a startup environment, applying financial-grade rigor while keeping pace with a lean team

Nice to have

• Experience with double-entry accounting or general-ledger design
• A background in fintech infrastructure or another highly regulated, high-stakes environment
• Familiarity with gRPC/protobuf APIs and event-driven or workflow-orchestration patterns, such as Temporal
• Experience handling sensitive PII and building systems that meet KYC/AML compliance and security requirements

• Equity package
• Benefits that support life in and outside of work
• Funders & Founders program
