We’re Hiring: Senior Full-Stack Product Engineer/ Solution Architect!

We are seeking a visionary Senior Full-Stack Product Engineer and Solution Architect to lead the design and development of our next-generation software products. The ideal candidate will bridge the gap between complex business requirements and scalable technical solutions, ensuring high performance, security, and seamless user experiences across our entire ecosystem.

Location: San Jose, United States
Work Mode: Work from Office
Role: Senior Full-Stack Product Engineer/ Solution Architect

What You'll Do:

• Architect and build scalable full-stack applications using modern frameworks and cloud infrastructure.
• Lead technical decision-making and define system architecture for high-traffic platforms.
• Collaborate with product managers and designers to translate vision into functional code.
• Mentor junior engineers and conduct rigorous code reviews to maintain high standards.
• Optimize application performance and ensure security best practices across the stack.

Role Overview

We are seeking a senior, hands‑on engineer who can translate a PMO process into a dependable product and own the solution end to end. This role combines product thinking, application architecture, full-stack implementation, data engineering, and enterprise operations. The successful candidate will shape the right workflow, explain key design decisions, and deliver an application that teams can use and trust in production.

Key Responsibilities

• Lead product and solution architecture, clarify requirements with stakeholders, and turn them into a practical delivery plan.
• Design and implement the application across its user experience, APIs, persistence layer, integrations, deployment, and operational documentation.
• Make sound tradeoffs for security, usability, data integrity, maintainability, and future reporting.
• Partner with PMO, product, data, security, and operations stakeholders through launch and ongoing support.
• Workflow and UI design. Turn the PMO process into a simple update flow with an editable milestone grid, product and revision groups, field validation, date variance, and “Path to Green” prompts. Build accessible, keyboard-friendly data-entry experiences.
• Application and database design. Build secure APIs and a transactional data model for programs, product revisions, milestones, owners, statuses, and dates. Support concurrent edits safely and shape data for future reporting.
• Field-level audit history. Capture who changed each field, when, and its previous and new values. Include a change reason where appropriate, and retain audit events separately from current values.
• Snowflake integration. Design reliable data movement, authentication, error handling, retries, reconciliation, and monitoring. Clearly explain how application data enters Snowflake and stays in sync. Snowflake Streams and Tasks can support CDC patterns after changed data is in Snowflake; define the upstream movement and synchronization design as part of the solution.
• Enterprise security and operations. Implement SSO, role-based access, protected credentials, deployment pipelines, backups, logging, and support documentation. Apply least-privilege access and appropriate authentication for application connections.
