Job summary

Zipliens is seeking a Senior Backend Software Engineer to build the core systems powering our data-heavy lien resolution platform for personal injury law firms. You’ll own integrations, design scalable APIs, and mentor engineers while leveraging AI-first tooling to process medical records and lien documents accurately and at scale.

You’ll collaborate with partner teams and help shape our backend infrastructure and patterns.

Qualifications

• 6+ years of backend software development in production.
• Significant experience with Python/Django or a comparable framework (Node.js, Rails, Laravel).
• Experience designing and building APIs that other teams or external parties consume.
• Experience integrating third-party APIs, especially where data is inconsistent.
• Hands-on AWS experience - EKS/EC2, RDS, S3, and queueing (SQS or similar).
• You should understand the infrastructure your services run on, not treat it as someone else’s problem.
• Strong SQL and PostgreSQL, including query optimization and schema design against large tables.
• Hands-on experience with LLM or ML features, whether in production or through prototypes and experimentation: prompting, evaluation, and understanding how they fail.
• Experience using or experimenting with agentic coding tools, and interest in building tooling around them.
• Experience mentoring engineers and raising standards on a growing team.
• Excellent written and verbal communication - you’ll be explaining technical constraints to non-technical stakeholders and to external partners.

Responsibilities

• Own third-party integrations end to end, and help build the platform that makes new ones fast to stand up.
• You’ll work directly with counterparties’ technical teams to define contracts, handle their data formats, and build the abstractions that keep one-off integrations from becoming permanent maintenance debt.
• Build and operate ML/LLM systems that extract structure from medical records, lien correspondence, and other unstructured documents - including the evaluation and monitoring that tells you whether they’re actually working.
• Refactor and decompose monolithic services into systems that scale independently - and operate them once they’re live.
• Mentor mid-level engineers and set the bar in code review.
• We’re adding engineers quickly this year; the seniors we hire now establish what good looks like for everyone who follows.
