About the role

WeTheHobby is evolving from a high-growth startup into a mature, event-driven enterprise. We are seeking a Senior Software Engineer to act as an architectural partner to the SVP of Engineering. Your mission is to help define the blueprint for our future state: decoupling our monolith, eradicating spreadsheet-dependency, and building a "Central Nervous System" that connects our operational tools with our financial truth.

The right candidate is an "AI-Augmented Systems Architect." This isn't a role for someone who wants to sit in a corner and close tickets; it’s for a key thinker who wants to shape the very bones of a company.

We are looking for the right-hand to the SVP of Engineering, someone who will act as a partner that can recognize flaws and fix them on their own rather than waiting for instructions.

This is an on-site role at our flagship facility in the Neighborhood of the Arts in Rochester, NY with the potential for fully remote working.

What you'll do

• Co-Architect the Blueprint: Work alongside the SVP of Engineering to design a Service Oriented Architecture (SOA) that is resilient, observable, and built for 10x scale.
• Modernize & Decouple: Strategically break down the legacy monolith into domain driven services, ensuring zero downtime and high data integrity.
• AI-Accelerated Engineering: Champion the use of AI tools (Cursor, Claude, LLMs) to accelerate design, refactoring, automate documentation, and rapidly prototype new system components.
• Eliminate Manual Friction: Systematically replace manual spreadsheet workflows with robust, automated digital processes that live within our platform.
• Technical Mentorship: Level up the engineering team by setting a high bar for code quality, architectural thinking, and the adoption of modern development tools.

The Tech Stack:

• Frontend: React/Typescript
• PostgreSQL (RDS), Entity Framework, Event-Driven Patterns
• Observability: Structured Logging (Serilog/Seq)
• AI Tooling: Advanced proficiency in Cursor, Claude Code, or LLM-driven architectural design.

Qualifications

• Bachelor’s degree in Computer Science, Software Engineering, Computer Engineering, or a related field, or equivalent practical experience.
• Proven experience building, scaling, and optimizing technology infrastructure at a Series B, C, or D startup in the technology, eCommerce, media, entertainment, or streaming sectors, or at another high-growth company.
• Led or played a significant role in migrating a monolithic application architecture to a service oriented or microservices-based architecture.
• Familiarity with Whatnot, Fanatics Live, or similar livestream commerce platforms, as well as the eCommerce, collectibles, media, or entertainment industries.
• Excellent communication, collaboration, and leadership skills, with the ability to influence cross functional stakeholders and drive technical initiatives.
