About the role

Bluefish AI is looking for a Senior Backend Engineer to own the data platform infrastructure that powers our AI marketing platform; building the systems that reliably move and process data at scale. This role sits within the Data Engineering team and focuses on building scalable, observable, and resilient systems that handle production data. You will work closely with data engineers and product teams to level up data pipelines and ensure data acquisition scales with the business. This is an exciting opportunity to shape the future of AI‑driven technologies and make meaningful contributions to real‑world applications. This role is based in our NYC office and follows a hybrid working policy with 3 days in office.

Requirements

5+ years building and operating production backend or data platform systems.

Strong distributed systems fundamentals: event-driven architectures, async processing, message queues.

Experience with AWS: SQS/SNS, Kafka, Lambda, ECS, S3, and EventBridge.

SQL and NoSQL database experience (PostgreSQL, DynamoDB).

Experience designing systems with robust error handling, idempotency, and reliable delivery guarantees.

Comfortable working across languages; our stack is Python and TypeScript and you'll be expected to be productive in both.

Experience mentoring mid/junior engineers and raising the technical bar across a team.

Experience with pipeline orchestrations.

Background in web scraping or data acquisition at scale.

Familiarity with vector databases or ML-adjacent infrastructure (embeddings, inference endpoints).

Experience with big data, especially with AI/ML platforms and use-cases.

Infrastructure as Code experience (Terraform).

Ability to partner with product, AI, BI, and data science teams as a technical thought partner, translating business and analytical needs into data platform decisions.

Experience working across time zones in distributed teams, with a track record of defining collaboration rhythms (communication standards, documentation practices, and ceremonies) that keep geographically dispersed teams aligned.
