Full Job Posting

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.
  • Build and maintain backend services and data processing workflows over large datasets, automating what's currently manual.
  • Operate what you build: troubleshoot production issues and implement security practices appropriate to sensitive legal and medical data.
  • Work directly with internal stakeholders to translate business needs into technical solutions.

Qualifications:

  • 6+ years of software development experience building and maintaining backend systems 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 or partner APIs, especially where the data is inconsistent, and the counterparty's documentation isn't solid.
  • 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.

Nice to Have:

  • Experience with document processing or extraction from unstructured data.
  • Working knowledge of React and JavaScript. Backend is the focus, but we'd like someone who can pick up frontend work when it unblocks them.
  • Familiarity with Kubernetes. We have an SRE who owns the cluster - you won't be running it, but you'll be deploying to it and debugging your services in it.
  • Experience handling sensitive data such as PHI, or working under HIPAA-style requirements.

Benefits

  • Private Health Care Plan (Medical, Dental & Vision)
  • Company HSA contributions for HDHP participants
  • Flexible Spending Accounts (Health & Dependent Care)
  • Company-Paid Short-Term Disability Coverage
  • Voluntary Long-Term Disability, Life, AD&D, and Supplemental Coverage Options
  • 401(k) Plan with Company Match
  • Paid Time Off (Vacation, Sick Time & 10 paid Holidays)
  • Parental Leave
  • Pay Disclosure: The total base salary range for this role is $136,000 - $184,500 annually with an opportunity to earn a discretionary quarterly bonus. Final compensation will be determined based on skills and experience.
