Описание

Responsibilities

  • Lead the scoping, design, and delivery of complex backend systems in Python on AWS: services, data models, and asynchronous pipelines.
  • Build and scale LLM-based systems that process large volumes of unstructured documents and data with precision and explainability.
  • Design external-facing APIs and integrations with third-party systems that customers depend on.
  • Own database and query performance as data volume grows; proactively manage technical debt.
  • Contribute to architectural discussions and decisions across the entire product, and iterate with teams to modify and prioritize within the development effort.
  • Accurately estimate your work, consistently meet deadlines, and help others estimate theirs.
  • Take a leading role in incident and bug resolution; be the strong debugger others turn to.
  • Lead the adoption of best practices for development, testing, and deployment.
  • Mentor other engineers through code review, pairing, and design feedback.
  • Use AI tooling deliberately to multiply your own output and quality.

Requirements

  • 5+ years of software engineering experience building and operating backend systems in production.
  • Know Python (our main stack), though we're open to strong candidates from other OO backgrounds.
  • Experience with AWS and serverless technologies (Lambda, Step Functions), asynchronous workflows, and cloud environments.
  • Strong knowledge of relational databases and their performance tuning, ideally PostgreSQL.
  • Mastery of software development fundamentals: system design, debugging, testing, and problem-solving.
  • Experience building external-facing APIs or designing integrations with third-party systems.
  • You take full ownership of your work and drive projects to completion with minimal oversight.
  • You communicate proactively: surfacing blockers, asking the right questions, keeping stakeholders in the loop.
  • You thrive on experimentation: comfortable testing ideas, measuring results, and iterating quickly on problems no one has solved before.
  • You're excited by problems others are struggling with.

Nice to have

  • Experience working with LLMs in production and an understanding of what it takes to deploy them at scale.
  • Experience with document pipelines and processing large amounts of data.
  • Experience with distributed systems.
  • Experience in insurance, fintech, or another data-heavy regulated domain.

We offer

  • Competitive salary (based on experience level)*.
  • Significant equity options package.
  • 20 days of PTO a year.
  • Global team offsites (2024 - Lisbon, 2025 - Cartagena, 2026 - Tbilisi).
  • Healthy living/gym stipend.
  • Mobile phone bill stipend.
  • Continuing education credits.
  • For US employees only: 100% covered medical, 100% covered vision and dental for individuals and families.
  • 401(k) plan with employer contribution (regardless of employee contribution)
