About the Role

As a Senior Software Engineer (Backend) at Pangram, you will design, build, and scale the production systems that serve our core technology to a rapidly growing user base and own the backend infrastructure that powers Pangram's AI detection platform. This is a senior, high-autonomy role: you'll make architectural decisions, solve hard scaling problems, and ensure our systems are reliable and performant as demand grows. You'll work across our Django backend and AWS infrastructure, collaborating closely with our frontend and machine learning teams.

This is a full-time, on-site role in our Brooklyn office reporting to our CTO.

What You'll Do

• Design and implement scalable backend services and APIs to serve AI detection capabilities at scale

• Own the reliability, performance, and observability of production systems

• Architect and maintain data pipelines, caching layers, and service infrastructure on AWS

• Collaborate with ML engineers to deploy and serve machine learning models in production

• Identify and resolve bottlenecks across the stack as traffic and complexity increase

• Establish and improve engineering best practices around testing, deployment, and incident response

Qualifications:

You are a great fit for this role if you have:

• 5+ years of professional software engineering experience, with a strong backend focus

• Proficiency in Python and Django (or comparable Python web frameworks)

• Deep understanding of backend architecture patterns: RESTful API design, relational databases, message queues, caching strategies, and asynchronous task processing

• Hands-on experience with AWS services (e.g., EC2, ECS/EKS, RDS, S3, SQS, CloudFront, Lambda)

• Experience designing systems for high availability, horizontal scalability, and graceful degradation

• Strong debugging and performance-profiling skills in production environments

Strongly Preferred

• Experience with containerization (Docker) and container orchestration (Kubernetes)

• Familiarity with CI/CD pipelines and infrastructure-as-code tools (Terraform, CloudFormation, or similar)

• Experience with monitoring and observability tooling (e.g., Datadog, Prometheus, Grafana, ELK)

Nice to Have

You are an exceptional fit for this role if you also have:

• Experience deploying and serving deep learning models in production (model serving frameworks, GPU infrastructure, batch vs. real-time inference)

• Familiarity with React or frontend technologies sufficient to collaborate effectively across the stack
