Job Details

Our client is hiring a Senior Software Engineer to help design, build, and scale intelligent software agents that drive automation across their Ruby and AWS-based platform.

Why the Change to Python:
Our client's core backend is currently written in Ruby/Rails - a decision based on early founder expertise, not architectural fit. As they scale, they've identified significant limitations. They are considering transitioning to Python for long-term infrastructure and agent services in the mid-to-long term. However, they need engineers now who can help us stabilize and scale what we have - then lead the evolution.

You'll work closely with leadership, product, and customer-facing teams to build core systems that power real-time document workflows, automation triggers, and integrations that help financial institutions move faster.

Responsibilities
Own and drive technical projects from architecture to delivery
Build scalable, fault-tolerant services on AWS (Lambda, ECS, RDS, S3, CloudWatch, etc.)
Refactor legacy code for long-term clarity, testability, and scalability
Translate customer and product insights into high-leverage workflow automation
Participate in the on-call rotation to ensure uptime and reliability
Help shape team culture through mentorship, feedback, and ownership
