Position Overview:

We are seeking a collaborative, proactive, and results-driven full stack Software Engineer with a strong backend emphasis to join our dynamic team. In this role, you will play a crucial part in developing and maintaining custom cloud-based applications for Vibes customers, with a focus on backend development and lightweight server-rendered frontend work delivered through discrete, project-based engagements. The primary stack is Ruby on Rails; engineers with solid backend fundamentals in comparable languages such as Python or JavaScript/TypeScript are encouraged to apply. Additionally, you will contribute to AWS infrastructure managed through Terraform, ensuring optimal performance and scalability across our cloud services.

An ideal candidate possesses a growth mindset, strategic thinking capacity, and strong communication skills. This role holds significant impact at Vibes during a period of exciting growth. In a world marked by constant change and uncertainty, one area that's growing rapidly is the digital consumer engagement space - specifically, how brands establish personalized, 1-on-1 interactions with consumers at scale. This role places you at the heart of this exciting evolution in consumer engagement. The position reports to the Senior Director of Professional Services and offers hybrid work in the Chicago metro area. If you're eager to build systems that offer large enterprises the latest innovations in mobile marketing technology and spread positive vibes, then you have an opportunity to thrive here.

This is a full-time, hybrid position based in the greater Chicago metro area, reporting to the Senior Director of Professional Services. Vibes has been recognized in 2026 as a Built In Best Places to Work.

Primary Responsibilities:

Feature development with guidance:

• Build and extend features across backend services and admin applications, working from well-defined tickets with senior engineer support
• Implement data models, API endpoints, and lightweight frontend components in a server-rendered context
• Write clean, tested code and participate in MR-based code review as both author and reviewer

Infrastructure and deployment:

• Make targeted infrastructure changes within established Terraform module patterns like adjusting variables, modifying resource configurations, and promoting changes across environments
• Participate in CI/CD pipeline workflows and understand how infrastructure and application releases interact across dependent services

Operational work:

• Write scripts to initialize, migrate, and transform data across relational and NoSQL data stores
• Investigate production issues using cloud-native observability tools (logs, metrics, and distributed tracing) escalating when appropriate and building diagnostic skills over time

• Read and contribute to architectural documentation as you build context on the system

Required Qualifications:

• Comfort with relational databases: writing queries, understanding joins, and working with migrations (PostgreSQL preferred)
• Familiarity with REST APIs: consuming them, understanding request/response patterns, and debugging integration issues
• Hands-on AWS experience with core services: Lambda, SQS, S3, RDS, and CloudWatch. You should be comfortable navigating the console, reading logs, and reasoning about how these services interact
• Exposure to infrastructure-as-code concepts, ideally Terraform, like reading existing configurations, understanding what a terraform plan is telling you, and making changes within established patterns
• Git-based workflow: branching, pull/merge requests, resolving conflicts
• Excellent problem-solving skills and the ability to troubleshoot complex issues across the full stack
• Strong communication and collaboration skills, with the ability to work effectively in a fast-paced, team-oriented environment
• Passion for learning and staying updated on emerging technologies, best practices, and industry trends
• Dedication to delivering high-quality solutions that meet the needs of our clients and stakeholders, with a focus on usability, reliability, and scalability
