Build and improve core Opportunity Engine features, business logic, and integrations.

Design and optimize PostgreSQL databases and data models.

Write automated tests and participate in code reviews.

Deploy and maintain services using Docker and AWS.

Troubleshoot production issues and improve performance, security, and reliability.

Collaborate with frontend and product teams to deliver features end-to-end.

Understand and contribute to the broader application stack when required.

Required Qualifications

2+ years of professional software engineering experience, with strong backend experience.

Currently pursuing or have completed a Bachelor’s or Master’s degree in Computer Science, Information Systems, or a related field.

Strong proficiency in Python and experience with FastAPI or a similar framework.

Experience building REST APIs and working with PostgreSQL.

Experience with SQLAlchemy/SQLModel and database migrations.

Working knowledge of React, JavaScript, and TypeScript.

Experience with Git and Docker.

Familiarity with cloud environments, preferably AWS.

Understanding of software engineering fundamentals, testing, debugging, and API design.

Strong problem-solving and communication skills.

Nice to Have

Experience with pgvector, embeddings, semantic search, or AI/ML integrations.

Experience with WebSockets or real-time applications.

Experience with GitHub Actions / CI/CD.

Experience with AWS EC2, RDS, and S3.

Experience working in an early-stage startup or small engineering team.

What We're Looking For

We are looking for a backend-focused engineer with full-stack awareness who can work independently, understand an existing codebase, take ownership of features, and make thoughtful decisions around performance, security, scalability, and maintainability.

The ideal candidate is comfortable learning across the stack and working in a fast-moving startup environment.
