Senior Backend Engineer (Python)

As our Senior Backend Engineer, you’ll design and build the backend infrastructure that supports high-throughput, reliable, and secure AI agent workflows. You’ll work cross-functionally with ML engineers and data scientists to operationalize models at scale.

 

 

Architect and implement scalable APIs, microservices, and event-driven systems to power ML pipelines and agent orchestration

Design efficient data modeling, ETL, and persistent storage suited for high-volume, real-time agent data 

Optimize backend performance and ensure system stability under heavy concurrent load

Collaborate closely with founders and ML teams to deliver end-to-end agent features

Establish CI/CD pipelines, monitoring frameworks, and enforce backend security best practices

Mentor junior engineers and contribute to team culture and best practices

 

 

5+ years designing, implementing, and maintaining backend systems in Python

Experience building distributed, scalable services with microservices or serverless architectures

Strong grasp of relational and NoSQL databases, message queues (e.g., Kafka), and ETL patterns 

Proven track record in API design (REST/gRPC), authentication, and reliable asynchronous processing

Familiarity with containerization (Docker, Kubernetes) and observability tools (Prometheus, Grafana)

 

 

Prior experience launching AI products or backend systems for ML/agent-driven applications

Knowledge of LLM APIs, prompt pipelines, and agent orchestration

Familiarity with cloud-native tools (AWS Lambda, S3, DynamoDB, GCP/Azure equivalents)

Experience in startup or early-stage environments

 

 

Competitive equity & pay - get in early and own what you build.

Work closely with experienced founders with a proven startup track record.

Move fast, ship fast - no corporate bureaucracy.

Shape the AI revolution in healthcare - massive market, untapped potential

We’re transforming front office operations for healthcare practices through AI-first automation. Think agentic AI that streamlines insurance verification, claim management, pre-authorization, denials management, coding and reviewing notes, and every mundane, repetitive task that bogs down practice staff. Our mission? Free up healthcare professionals to focus on what matters most: their patients.
