Staff Software Engineer

What You'll Do
Set technical direction across the bank's systems. Own the medium-to-long-term technical strategy for the bank's core surfaces — cloud infrastructure, data platform, core banking configuration, CI/CD, networking, and the Bank ↔ Affirm Inc integration — and make the architecture calls the rest of the team builds against. Generalist breadth is expected; you go deep where the risk is highest.
Own the hardest problems end-to-end. Personally design, build, integrate, and operate the most ambiguous and highest-stakes pieces of the stack, and own incident response for them. You take the problems no one else can fully scope and turn them into well-defined systems with clear failure domains, monitoring, and runbooks.
Be the force multiplier on a small team. Set and hold the bar for code review, design review, and examiner-readable documentation. Establish the patterns and standards that let a deliberately small team punch far above its size, and level up every engineer who joins after you.
Ship AI-first, and push the frontier of it. Treat AI tools and agentic workflows as a load-bearing capability for code, design review, runbook generation, and operations — and actively push yourself and the team on what an AI-leveraged engineering function can deliver in place of additional headcount.
Lead vendor selection and ownership. Drive evaluation, integration, and ongoing oversight of the bank's third-party platforms across the core, data, identity, observability, and card-processing stacks. Carry the bank's most critical vendor relationships end-to-end: integration, operations, escalation, and audit.
Define the integration boundary with Affirm Inc. Set the domain edges, data flows, and integration patterns between the bank and Affirm Inc so the bank's products work seamlessly inside the Affirm ecosystem while preserving the legal and regulatory separation the charter requires. Drive this across Affirm Inc engineering teams whose systems integrate with the bank's.
Build for examiners. Partner with Legal, Compliance, Risk, BSA/AML, Finance, and Internal Audit so compliance is a property of the product from day one. The systems you design are the artifacts FDIC and state examiners will inspect — design and document them to a standard that holds up under examination and audit review.
Own the operational posture of the bank's systems. Set the reliability, observability, alerting, runbook, incident-response, and disaster-recovery practices that keep the bank standalone-operable and audit-ready, while keeping the operational footprint intentionally small.
Influence up and across the organization. Communicate technical strategy, tradeoffs, and constraints with clarity to bank executives, the Bank Board, Compliance, Risk — and to engineers outside the bank across the broader Affirm org. The relationships you build beyond the team shape how cleanly the integration boundary works.
Help grow the team and the bar. As engineers join, they inherit a function whose architecture, practices, and standards you helped set. Mentor peers, provide high-signal feedback, contribute to hiring, and lead by example.
What We Look For
8+ years of software engineering experience, with staff-level, hands-on builder credentials and a track record of owning ambiguous, high-stakes systems end-to-end through launch and operations
Comfortable owning ambiguity at the largest scale on the team — you move fast, make the tough prioritization calls, take ownership before being asked, and balance speed with the engineering judgment the hardest decisions require
Hungry to leverage AI to drive outcomes — fluent with AI-assisted development tools (Claude, Cursor, Codex, agentic workflows) and actively pushing yourself and your team to use them as a multiplier for code quality, velocity, and what a deliberately small team can ship
Bias toward simplicity — experience building toward a small, lean engineering culture that rewards "buy over build", a default-deny posture, and standalone-operability over an abundance of tooling
A track record of setting technical direction — you've defined architecture and multi-quarter technical strategy for systems beyond your own projects, and led the execution of it across engineers and teams without needing a management title to do so
Deep systems thinking across public cloud infrastructure (AWS preferred), infrastructure-as-code (Terraform), and cloud data platforms (Snowflake or comparable) — you understand their failure modes and tradeoffs, not just their surface APIs
Regulated-environment experience — direct work in banking, payments, securities, healthcare, or another setting subject to external examination, where the work involves examiner-facing documentation and decisions
Direct experience selecting, integrating, and operating meaningful third-party platforms under operational ownership after launch
Comfortable as the technical face of the work to non-engineering stakeholders — bank executives, the Board, Compliance, Risk, Finance, and examiners — and able to document decisions so they hold up under audit review
Exceptional written and verbal communication — you can distill complex technical, regulatory, and operational concepts into clear narratives for executives, boards, and non-engineering audiences
Nice to have
Prior work inside a bank, neobank, Banking-as-a-Service provider, card issuer/processor, or fintech with a chartered bank subsidiary
Direct experience with a de novo bank launch, an early-stage bank buildout, or a greenfield regulated platform
Hands-on experience with a bank core, card processing / issuer processor integration, or digital bank experience integration
Hands-on experience standing up a greenfield cloud organization — fresh cloud org, IAM model, and data platform — under a tight, default-deny security posture
Familiarity with the regulatory framework that shapes the work: FDIC examinations, GLBA / Reg P (affiliate data sharing), BSA/AML, Reg E, Reg DD, Reg Z, model risk, and third-party risk management

Skills Required
8+ years of software engineering experience with staff-level, hands-on builder credentials
Proven track record owning ambiguous, high-stakes systems end-to-end through launch and operations
Ability to own ambiguity at large scale, prioritize, and take ownership proactively
Fluency with AI-assisted development tools and agentic workflows (e.g., Claude, Cursor, Codex)
Deep systems thinking across public cloud infrastructure (AWS preferred), infrastructure-as-code (Terraform), and cloud data platforms (Snowflake or comparable)
Regulated-environment experience (banking, payments, securities, healthcare, or similar) involving examiner-facing documentation
Direct experience selecting, integrating, and operating third-party platforms under operational ownership
Experience setting technical direction and multi-quarter technical strategy across teams without a management title
Ability to act as technical face to non-engineering stakeholders and document decisions to hold up under audit
Exceptional written and verbal communication skills
Experience owning incident response, reliability, observability, runbooks, and disaster recovery for production systems
Prior work inside a bank, neobank, BaaS provider, card issuer/processor, or fintech with a chartered bank subsidiary
Experience with de novo bank launch, bank core or issuer-processor integrations, or greenfield regulated platform builds
Hands-on experience standing up a fresh cloud org, IAM model, and data platform under a tight default-deny security posture
Familiarity with regulatory framework (FDIC exams, GLBA, BSA/AML, Reg E, Reg Z, Reg DD, model risk, third-party risk management)
