Senior Backend Software Engineer

At Spring Labs, we’re building a unified platform that powers end-to-end workflow automation for customer support and compliance teams in financial services. Our AI-native system interprets customer intent, understands regulatory nuance, and orchestrates complex processes through configurable automation — helping banks and fintechs scale service, reduce manual work, and stay audit-ready without adding headcount.

We’re looking for a Senior Backend Engineer who can own core services end-to-end : ingestion, processing, orchestration, and delivery at scale. You’ll work closely with product, data science, and infra to evolve a system that processes high-volume, high-stakes customer interaction data—reliably and fast.

If you're passionate about tackling complex problems with a team of accomplished professionals, and the opportunity to learn from domain experts excites you, we’d love to hear from you!

What you’ll do

• Design, build, and operate backend services and APIs that power Spring Labs’ core platform
• Own data ingestion and processing pipelines (batch + real-time) for large, messy, multi-source datasets
• Productionize machine-learning workflows by integrating models into backend systems with clear contracts, monitoring, and rollback paths
• Design and maintain scalable service architectures (APIs, workers, queues, schedulers)
• Improve system reliability through better testing, observability, error handling, and automation
• Partner closely with data science to turn experiments into durable, production-grade systems
• Influence architecture decisions and set backend engineering standards as the platform scales

About you

• 3+ years of professional software engineering experience, with a strong backend focus
• Strong proficiency in Python ; experience with distributed systems is a plus
• Hands-on experience designing and maintaining RESTful APIs and backend services
• Experience working with data pipelines and processing frameworks
• Exposure to event-driven systems, queues, or workflow engines
• Comfortable deploying and operating services in production (monitoring, debugging, scaling)
• Familiarity with databases (relational and/or NoSQL) and data modeling
• Experience integrating ML/LM models into production systems
• Strong engineering judgment—knows when to build, refactor, or simplify
• Comfortable using AI-assisted and agentic coding tools as a force multiplier —to accelerate development, improve code quality, and explore solutions faster, while maintaining strong engineering judgment and ownership of the final output.
