Backend Developer

Location: Kansas City, MO (Remote-First) Type: Full-Time Level: Mid to Senior

Join Pumpfiat as a Backend Developer and build the secure, scalable systems that process and deliver millions of permission-based prospects with unwavering reliability and compliance.

About the Role

You’ll design and maintain the core infrastructure that powers Pumpfiat’s data pipeline, API layer, and compliance features. Your code will handle high-volume data processing while ensuring security, auditability, and performance — directly impacting client deliverability and trust.

This is a remote-first role with a preference for candidates able to collaborate effectively with the Kansas City, MO timezone.

Key Responsibilities

• Design, build, and maintain scalable APIs and microservices using Node.js and/or Python.
• Develop secure data pipelines for ingestion, cleansing, segmentation, and export of millions of records.
• Implement robust compliance features (consent tracking, audit logs, encryption at rest/in transit).
• Optimize database performance (PostgreSQL, MongoDB, or similar) and query efficiency at scale.
• Collaborate on system architecture, security reviews, and infrastructure decisions.
• Write clean, tested, and well-documented code with monitoring and alerting built in.

What We’re Looking For

• 4+ years of professional backend development experience.
• Strong proficiency in Node.js (Express/NestJS) or Python (FastAPI/Django).
• Experience building RESTful and/or GraphQL APIs at scale.
• Deep knowledge of relational databases (PostgreSQL preferred) and query optimization.
• Familiarity with cloud platforms (AWS, GCP, or Azure) and infrastructure as code.
• Understanding of security best practices (encryption, OWASP, GDPR/CCPA data handling).
• Ownership mindset — you take pride in systems that are reliable, observable, and maintainable.

Nice to Have

• Experience with data processing tools (Kafka, Spark, Airflow, or similar).
• Background in email infrastructure, deliverability, or compliance-heavy environments.
• Contributions to open-source projects or a strong GitHub presence.
