Hiring Company: ION Water

One-liner: ION transforms the way water costs are controlled through affordable housing’s only smart End-to-End Water Management solution. The Software Architect will own the data architecture and lead a distributed engineering team to ensure data correctness and high-quality code for the ION platform.

Salary: $150K/yr - $170K/yr

Why Join Us:

• • End-to-end smart water management platform transforming how multifamily housing controls water costs, with 20,000x more granular data than traditional meters
• • Partnered with Meta on a 26M gallon conservation initiative, 100K+ units deployed, trusted by 1/3 of top U.S. affordable housing developers
• • Remote-first environment with competitive compensation and benefits.

Role Responsibilities

• • Own the data architecture and correctness of the ION platform — relational and time-series modeling, reconciliation, and the integrity of high-volume meter data
• • Lead and mentor a distributed engineering team, and raise the quality bar without adding unnecessary process
• • Set and document architecture direction across the stack — serverless backend, data products, and the React / Next.js front end
• • Build and ship production backend code in TypeScript and Node.js
• • Make pragmatic build-versus-buy and storage decisions based on scale, reliability, maintainability, and cost
• • Improve testing, observability, code review, and deployment discipline across the team
• • Partner with Product, Operations, Sales, and the CTO to turn business requirements into technical plans

Qualifications

Required

• • Data-first engineer: deep in relational data modeling and SQL performance tuning at scale on a major relational database (PostgreSQL, Oracle, SQL Server, or MySQL)
• • Experience ensuring data correctness, including reconciling internal systems against an external source of truth
• • Experience with time-series or high-volume operational data — or strong relational depth and the ability to ramp into it
• • 5+ years building production backend, data, or cloud systems; 3+ years in a senior technical role (Architect, Staff / Principal Engineer, or hands-on Engineering Lead)
• • Demonstrated experience leading and mentoring engineers on a distributed team
• • Deep AWS serverless experience (Lambda, SQS / SNS, S3, DynamoDB, IAM, VPC) and infrastructure-as-code
• • Strong TypeScript / Node.js — or comparable backend depth and the ability to become productive quickly
• • Comfortable reasoning about and reviewing a React / Next.js front end
• • Strong grasp of idempotency, retries, dead-letter handling, ordering, backfills, and incident response

Preferred

• • PostgreSQL and TimescaleDB (our current stack)
• • MQTT or other device / IoT telemetry experience at scale
• • Utility, energy, water, building-operations, or billing domains
• • Anomaly detection, signal processing, or time-series analytics
• • S3-based analytics — Athena, Glue, Parquet
• • Docker, ECS / Fargate, ECR, and CI/CD pipelines
• • TypeScript / Node.js
• • PostgreSQL / TimescaleDB
• • MQTT / IoT telemetry
• • React / Next.js familiarity
