A hands-on individual contributor role. Most of your time goes to writing code, solving hard problems, and making architecture decisions as the platform scales.

What you'll do

  • Architect high-throughput systems for email delivery, reporting, calendars, and customer data integrations (Salesforce, SMTP, third-party APIs).
  • Modularize backend services for resilience and independent scaling.
  • Find and fix bottlenecks in PostgreSQL queries, API latency, and data-heavy operations.
  • Keep customer data syncs reliable as client volume grows.
  • Shape the technical foundation for AI features, from system design and data pipelines to production.
  • Improve developer experience and internal tooling.

What we're looking for

  • 8+ years building production backend systems, with strong Java/Spring Boot or a comparable framework.
  • Deep experience with relational databases at scale, ideally PostgreSQL: query tuning, multi-tenant schema design, partitioning.
  • Production AWS experience: architecting, deploying, and operating systems.
  • A record of owning complex backend projects end to end.
  • Sound technical judgment with incomplete information, and clear communication with engineers and non-engineers.

Nice to have

  • High-volume data integrations, bulk email, or large-scale API orchestration.
  • Multi-tenant B2B SaaS background.
  • Infrastructure as code (Pulumi, Terraform).
  • Building or integrating AI features in production.

Lead the work of embedding AI throughout Axle. A hands-on individual contributor role: you build customer-facing agentic features, ship frequently, and turn ambiguous problems into polished product.

What you'll do

  • Architect and ship agentic product experiences that large banks can trust with real work.
  • Make key architecture decisions that balance performance, cost, and maintainability.
  • Own the agent infrastructure: evals, guardrails, tool integrations, observability, and testing.
  • Build backend APIs (Python, Django/FastAPI) and AWS infrastructure, and work with product engineers on the UI.
  • Establish patterns, systems, and processes for the AI team as it grows.
  • Track new AI tools, models, and techniques for use in the product.

What we're looking for

  • 4+ years building production backend software, including 2+ years shipping LLM-powered features.
  • Deep experience with frontier models: prompting, tool use, context management, and the harnesses around them.
  • Experience making agentic systems production-grade: evals, guardrails, observability, and failure handling.
  • Ability to own work from concept to production on a small team.

  • Strong command of full-cycle enterprise sales, including prospecting, demos, negotiation, and complex procurement processes.
  • A consultative sales approach with the ability to engage and influence senior executives and decision-makers.
  • Excellent communication, presentation, and relationship-building skills.

  • Previous experience working at an investment bank.
  • Experience as an early sales hire at a high-growth startup, helping build and scale a sales function.

What we offer

  • Competitive base, uncapped commission with accelerators, and meaningful equity.
