Domain Owner — Core Banking

Nymbus (https://nymbus.com/) is not just a leader in fintech; we are a community of innovators passionate about reimagining banking. Our modern core platform and cloud based technology serve as the backbone for financial institutions eager to modernize and excel.

Nymbus is building the next generation of fintech platforms, and Domain Owners are among the most consequential leadership roles in delivering that vision. This role owns the Core Banking domain: the foundational system layer that processes every financial transaction, maintains every account balance, and enforces every posting rule across the platform.

WORK ENVIRONMENT:

We are a remote first company, with occasional travel required for team collaboration or client engagement.

POSITION SUMMARY:

The Domain Owner for Core Banking is the senior product leader responsible for the strategic direction, squad output, and commercial outcomes of the Core Banking domain at Nymbus.

You lead multiple squads that build and evolve the core banking engine — deposits, lending, account structures, posting models, settlement, interest accrual, and the fundamental ledger infrastructure that every other domain depends on. You manage Builders directly, collaborate daily with others assigned to your domain, and are accountable for everything your domain ships.

This is not a traditional product management role. You operate with four capabilities simultaneously: strategic product leadership, people leadership of Builders, domain subject matter expertise, and AI-first execution. You are expected to be a hands-on SME in core banking systems — someone who has designed, built, or deeply operated core banking platforms and can guide your teams through the complexity of core banking, from operations, finance, teller, to products, entitlements, GL and reconciliations.

ESSENTIAL JOB FUNCTIONS/RESPONSIBILITIES:

Strategic Product Leadership

Owns and executes on the product roadmap for the Core Banking domain

Define the vision for how Nymbus builds a modern, configurable, multi-tenant core banking engine

Prioritize squad work against business outcomes, client needs, and platform strategy

Represent the domain in executive planning, client conversations, and board-level updates

Drive commercial outcomes — your domain's reliability and capability directly impacts every client relationship

People Leadership (Builder Management)

Hire, develop, and performance-manage all Builders in the Core Banking domain

Set clear expectations for AI-first execution, specification quality, and delivery velocity

Coach Builders on domain expertise — particularly the nuances of ledger integrity, posting models, and regulatory constraints

Build a team culture of precision, ownership, and continuous improvement

Ensure Builders operate at the Nymbus hiring bar and AI fluency standard

Domain Subject Matter Expertise

Serve as the authoritative SME for core banking within Nymbus

Design and reason about account hierarchies, sub-ledgers, and posting models including memo posting, hard posting, reversals, and adjustments

Understand batch processing, end-of-day settlement, and cutover windows including how posting order and timing affect balances and downstream systems

Define product configuration logic for deposit products (fees, interest accrual, minimum balances, tiering, exceptions)

Model core-to-digital integration patterns including event propagation, synchronization delays, and reconciliation strategies

Address data integrity, auditability, and operational controls required for regulatory and financial reporting

Guide teams through loan servicing complexity — payment application logic, accrual calculations, payoff quotes, per-diem interest, and exception workflows

Understand regulatory frameworks deeply: Reg D, Reg CC, Reg DD, Reg Z, TILA, RESPA, and their operational implications on core system behavior

Navigate the tension between multi-tenant configurability and system correctness — every institution has different product configurations, but the ledger must always balance

AI Execution

Model AI-first working practices for the domain — use Kiro, Claude, and spec-driven development personally

Set the standard for how Builders in your domain leverage AI tools

Ensure specifications for core banking logic are precise, testable, and take full advantage of AI-augmented workflows

Drive continuous improvement in squad velocity through AI-native methodology

Evaluate and adopt new AI tools and practices that accelerate domain output

Recognize that core banking demands exceptional specification precision — AI tools must enhance, not shortcut, correctness

Cross-Domain Coordination

Coordinate with other Domain Owners on integration surfaces — Digital Banking, Payments, and Origination all depend on Core

Own the contract between Core and its consumers — define how other domains interact with the ledger, accounts, and posting engine

Partner with the Architecture Spine on platform-w…
