Job summary

Aboon is seeking an experienced senior back-end engineer to advance our Rails-based platform that powers Workplace and TPA products for 401(k) retirement administration.

You'll work across our Rails system, data connectivity layer, and major feature development to support fiduciary, auditable workflows used by advisors and business owners. Remote US-friendly position with strong compensation.

Qualifications

• 6+ years of professional software development experience.
• Deep expertise in Ruby/Rails: domain modeling, background jobs, API design, performance.
• Proven track record designing scalable APIs and data models — and strong instincts for permissions, idempotency, and auditability in systems that move real money.
• Proficient working with coding agents; we’re not hand-rolling boilerplate.
• Familiarity with AWS and infrastructure-as-code.
• Experience integrating third-party systems (payments, identity, CRM, payroll) and designing for their failure.
• Excellent communication skills and a collaborative mindset.

Responsibilities

• Own major feature development end-to-end across our products, from design doc through deployment and monitoring.
• Build the tool surfaces our agents act through: typed, permissioned, logged actions against our system of record, with staging-and-promote patterns so nothing writes to a plan without a gate.
• Design and run our data connectivity layer: recordkeeper feeds, payroll providers, payments, and identity.
• Make auditability a priority so that every action, human or agent, is traceable, explainable, and regulator-ready.
• Lead architectural discussions, write design docs, and mentor through code review.
