Senior Ruby On Rails Developer Jobs in Merrillville, IN

You'll be the sole people manager for an established team of 10 solid engineers (6 onshore, 4 nearshore) building the LOS/CRM platform behind our refinance process. The team is more than a third of Caribou's product engineering, and you'll be one of six leaders reporting to the CTO. 

The team operates in a Ruby on Rails monolith and a Python monorepo for Google ADK Agents. The strategic mandate for the role is to build agentic orchestration to guide our origination platform, automating the repetitive, high-volume steps of the refinance process so our team can spend more time on the applications and moments that need a person's judgment.

Round-the-clock agentic orchestration extends what our team can already do by handling routine steps at any hour so customers get faster answers, while our team focuses on the applications where a person makes the difference.

Separate from the product work, we're deploying agentic engineering across all repos using Claude Code. You'll improve your team's practice across practitioner capability and codebase readiness, targeting top-quintile productivity and helping define how we measure it.

The team is new to agentic orchestration, and bringing them up on it is the work. Within the year, we expect agentic orchestration to be handling the full range of routine refi steps, with our team focused on exceptions, edge cases, and judgment calls. Your management and architecture skills sharpen on the way, and scope grows as you prove it out.

• Build and hold the team: hiring, coaching, performance conversations, and career growth for ten engineers.
• You won't ship features. You will read designs, weigh trade-offs with senior engineers, and know how the system actually works.
• Keep the codebase healthy across quarters, including making the case to Product when tech debt needs paying down.
• Grow your team's agentic engineering practice, moving each engineer up our capability model through mentoring and pairing.
• Lead production health for your team's services: on-call rotation, alerts and monitoring, incident response, and the follow-through after.
• Guide secure SDLC for your team: vulnerability patching, threat modeling on new agentic surfaces, and origination workflows kept audit-ready under SOC 2 and GLBA.
• Partner with Product, design, security, and data. Product sets the roadmap. You decide how it gets built.
• Collaborate with the other engineering managers to set how we engineer at Caribou.

• Prior experience leading engineers who build and operate production applications and back-end integrations.
• Experience guiding a team's shift to agentic engineering, or adding AI into existing products for material business value.
• Customer-focused leaders with a passion for well-crafted software, committed to growing their own leadership and engineering skills.
• Experience leading a distributed team across time zones, including nearshore or offshore engineers.
• Full-stack understanding of production software systems, from hosts and HTML, to models and MCP, to databases and DNS, to runtimes and REST.
• Collaborative, people-first leaders who lead with context over command and control.

If you meet most of what's above and not all of it, apply anyway.
