About the Role

Join us in building the next-generation financial planning and forecasting platform that drives strategic decisions across our organization. As a Senior Full Stack Engineer, you’ll own critical services end-to-end, influence architecture, and mentor peers while delivering features that directly impact how Finance plans and analyzes billions in revenue. 

You’ll work across a modern, containerized microservices architecture—spanning frontend UX, backend APIs, and data modeling—while championing engineering best practices and reliability.

Essential Duties and Responsibilities:

• Build end-to-end features across the frontend (Next.js/MUI) and backend (FastAPI/Python) with clean, maintainable code.
• Design APIs & data models for financial planning, forecasting, and analysis workflows; ensure data integrity and performance in PostgreSQL.
• Own services in production: implement logging, metrics, tracing, alerting, and SLOs; debug issues across microservices.
• Performance & reliability: profile endpoints, tune queries, reduce page load times, and optimize containerized deployments.
• Security & compliance: apply secure coding practices, manage secrets, enforce least privilege in AWS, and support audit needs (e.g., access controls, data retention).
• Infrastructure as Code: define and evolve CloudFormation stacks, IAM policies, networking, and autoscaling strategies.
• CI/CD & quality: improve pipelines (GitHub Actions), automate tests, and champion code review standards and documentation.
• Collaboration: work closely with PMs, designers, Finance partners, and data engineers to translate business rules into resilient software.
• Mentorship & leadership: guide teammates, influence architecture decisions, and raise the engineering bar across the team.

• Solid knowledge of AWS, containers, CI/CD (GitHub Actions), and Infrastructure as Code (CloudFormation preferred).
• Proven track record in designing and operating microservices, REST APIs, and secure, scalable architectures.

• Excellent communication skills and the ability to collaborate with Finance stakeholders on complex business logic.
• Bachelor's degree in Computer Science or related field.

Preferred

• Experience with async workloads (Celery, queues like SQS), Redis caching, and domain-driven design.
• Knowledge of data pipelines/ETL and analytics workflows; comfort with forecasting/planning concepts.
• Exposure to role-based access control (RBAC), auditing, and compliance in enterprise settings.
• Performance tuning of React/Next.js (SSR/SSG, caching) and Postgres (query plans, indexing).
