Advance Your Career at Planstin

Located in Southern Utah, Planstin is at the forefront of benefits administration and business services. We simplify health insurance for employers and individuals, emphasizing cost-effectiveness and excellent service in a complex market. As our company grows, we’re looking for talented individuals eager to progress in their careers.

About The Role

We are looking for a Senior Full Stack Engineer to help build out the next generation of the Planstin Membership Platform—a complex system that spans membership management, pricing engines, CRM integrations, ETL pipelines, and an evolving AWS-based microservice architecture. In this role, you’ll work directly with the founder/architect who built the current system, take ownership, anticipate problems before they surface, and propose thoughtful solutions. The right engineer must be comfortable adapting their plan when the business direction shifts. This is not a narrow feature-factory role. We need someone who can see the whole system, understand how the parts interact, and help push the architecture forward.

This position is based in St. George Utah but we'll consider full time remote and out of state for the right candidate.

What You'll Do

Backend (Primary)

A large Nest.js backend powering:
Distributed services deployed with AWS CDK (Lambda, RDS, S3, EventBridge, ECS/Fargate, etc.)

Frontend

React SPA for internal and external membership tools
Admin dashboards, configuration UIs, step-based workflows, and data visualization
Integration with partner systems

DevOps / Infrastructure

AWS CDK (TypeScript) for infrastructure automation
CI/CD optimization
Observability, error handling, and performance tuning

Data & Domain Work

Implementing and refining a high-complexity relational schema
Helping convert messy real-world data into stable, normalized structures
Identifying inconsistencies in business rules — and proposing solutions

Additional Tasks Will Include

Spot architectural risks early
Suggest simplifications and abstractions
Build tooling when manual work becomes repetitive
Improve reliability of pipelines ingesting external data
Question things that “don’t smell right”
Understand the why behind every model, process, or mapping
Ask great questions
Provide options, not just code

Qualifications

6+ years professional experience building production systems
Deep experience with:
Node.js / TypeScript
Nest.js (or equivalent DI-based frameworks)
React
AWS (Lambda, S3, RDS, IAM, EventBridge, API Gateway)
AWS CDK (TypeScript)
Relational databases (PostgreSQL strongly preferred)
SQL, migrations, schema design, performance tuning
Strong grasp of system architecture and distributed workflows
Ability to reverse-engineer complex datasets and design clear abstractions
Comfortable reading messy real-world data and making sense of it
Very strong debugging and production-troubleshooting skill
Writes clean, maintainable, well-structured code
Proactively identifies problems and proposes solutions
Comfortable shifting direction when priorities change
