• Work closely with Product and Design to understand ambiguous problems, clarify requirements, and translate customer and business needs into high-impact technical solutions.
• Develop and refine core Sales Planning capabilities, including quota management, capacity planning, territory management, and AI-powered revenue planning.
• Optimize application and platform performance by identifying and resolving bottlenecks as the product scales to support complex enterprise-grade datasets.
• Help define technical requirements and contribute to the migration toward a common platform architecture across products.
• Design scalable data models, APIs, and system architectures capable of supporting complex business logic and high data volumes.
• Maintain high standards for code quality, automated testing, observability, reliability, and production readiness.
• Build and maintain reliable, observable production systems with a strong focus on uptime and operational quality.
• Leverage AI development tools effectively to accelerate engineering delivery while maintaining reliable and maintainable code.
• Contribute to the productization of AI within a new enterprise performance management offering and help shape its long-term technical foundation.
• Support the development of AI model feedback loops and, where applicable, evaluation and guardrail systems that improve model behavior and reliability.
• Mentor other engineers and contribute to a strong engineering culture centered on technical excellence, collaboration, and ownership.
• Participate in an on-call rotation to provide after-hours support, resolve critical issues, and help maintain system uptime.

Requirements:

• 5+ years of professional software engineering experience with strong full-stack proficiency.
• Strong experience with Python, React/TypeScript, and databases.
• Experience building and scaling products from early-stage development through production environments.
• Strong systems-thinking and architectural judgment, with the ability to design robust data models and APIs for complex business logic and high-volume datasets.
• Experience working closely with Product and Design teams and translating customer feedback and business requirements into effective technical solutions.
• Strong customer-centric mindset and product sensibility, with an ability to balance technical considerations with user and business outcomes.
• Proven experience building observable, reliable production systems and taking ownership of production quality and performance.
• Practical ability to use AI-powered development tools to ship reliable software efficiently.
• Excellent communication and collaboration skills, particularly in cross-functional product development environments.
• Strong ownership mindset and comfort operating in an early-stage product where requirements and priorities may evolve.
• Django experience is strongly preferred.
• Experience building AI model feedback loops to continuously improve model behavior is a plus.
• Experience implementing AI evaluation and guardrail systems is a plus, including offline and online evaluations, safety filters, policy enforcement, failure detection, human-in-the-loop workflows, and red-teaming.

Benefits:
