Summary

OneStream is the AI operating system for modern finance. As Sr. Director, Software and Quality Engineering, you will lead our unified software development and quality engineering organization, bringing both disciplines under one leader accountable for how we build, test, and ship the OneStream Platform.

You will direct and execute the strategy for front-end engineering, API development and integration, and test automation on our Microsoft-based stack (C#/.NET, React, and Azure), while making AI-enabled development and testing the default way our teams work. Just as important, you will grow the leaders and engineers who make it happen. This role suits a leader who has driven both software and quality engineering forward, knows OneStream and the CPM/EPM space, stays close to the technical decisions, and is energized by building people.

Primary Duties and Responsibilities

Engineering Strategy and Delivery

Direct the strategy for front-end, API/Integration, and quality engineering, aligned to business outcomes and partnered closely with Product, Architecture, Security, and CloudOps.
Lead development and QE as one organization, embedding quality into design, development, and release, and delivering predictably across multiple teams with clear priorities, measurable outcomes, and honest communication of risk.
Stay hands-on in architecture and design reviews, code and test reviews, and complex debugging, while balancing speed and stability and managing technical debt and modernization as part of the roadmap.

Front-End and API Engineering

Own the architecture, standards, and roadmap for OneStream’s React-based browser experiences, including performance, accessibility, design systems, and secure client-side design, in partnership with UX and Product.
Drive integration capabilities that connect OneStream to customer, partner, and ecosystem systems, including REST-based and event-driven patterns.
Build APIs and services on C#/.NET and Azure, establishing API-first development and contract testing so teams can build in parallel with confidence.

Quality Engineering and Test Automation

Define the quality framework: test strategy, coverage targets, release criteria, and metrics such as escaped defects, flakiness, and cycle time.
Lead automation across UI, API, integration, performance, and security layers, with quality gates built into CI/CD and testing shifted left.
Invest in test infrastructure, environments, and data, and partner with Support and Customer Success to turn customer-found issues into prevention.

AI-Enabled Engineering

Drive adoption of AI-assisted development, code review, and test generation across engineering and QE, and measure the impact on productivity and quality.
Apply AI to testing, including test case generation, self-healing automation, defect triage, and risk-based test selection.
Establish responsible AI practices covering security, governance, data privacy, and human review, and partner with data and AI teams to integrate models and intelligent workflows into the platform.

Team Growth and Culture

Lead, coach, and grow Engineering Directors, Managers, QE leaders, and Staff+ engineers, building a bench with clear succession plans.
Own talent strategy: hiring, onboarding, retention, performance management, and technical and leadership career paths for engineers and QE specialists.
