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.

Requirements

6+ years of professional software engineering experience, including 3+ years working across both frontend and backend on modern web apps.
Strong proficiency in Python (FastAPI) and PostgreSQL (schemas, migrations, performance, transactions).
Production experience with Next.js + MUI (or React + component libraries), TypeScript, and accessible UI.
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.
Familiarity with testing strategies (unit/integration/e2e), observability, and pragmatic documentation.
Excellent communication skills and the ability to collaborate with Finance stakeholders on complex business logic.
Bachelor's degree in Computer Science or related field.

Nice To Haves

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).
Familiarity with OpenAPI/Swagger, contract testing, and API versioning strategies.
Prior experience mentoring engineers or leading technical initiatives.
Master's degree in Computer Science or related field.

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.
