About Us

K2 Venture Partners is a hands-on software development studio specializing in AI-first problem solving and zero-to-one product development, founded by serial entrepreneurs who've built dozens of products and sold multiple companies. We partner with early-stage companies to transform bold ideas into market-ready products, with a core focus on achieving product-market fit through rapid, traction-centric development.

The Role

We're seeking an exceptional software engineer who combines technical excellence with pragmatic product thinking. As a full-stack generalist, you'll own entire features from database design to user interface, working closely with our product team to deliver cutting-edge software solutions. This role demands versatility and technical depth. While you'll touch every part of the stack, we especially value strong backend expertise—building robust APIs, designing scalable databases, implementing complex business logic, and integrating AI/RAG capabilities. You'll architect systems that can evolve with rapidly changing startup needs while maintaining the flexibility to jump into React when the frontend needs attention. You'll be a technical partner to founders, translating business requirements into elegant technical solutions and making critical architecture decisions that shape products from their earliest stages.

What You'll Do

• Design and implement scalable backend systems including APIs, databases, and microservices that power multiple startup products
• Build AI-powered features and RAG (Retrieval-Augmented Generation) systems to create intelligent, context-aware applications
• Architect data models and implement business logic that captures complex domain requirements while remaining flexible for iteration
• Develop responsive frontend interfaces using modern React patterns when needed to complete end-to-end features
• Collaborate directly with founders to understand their vision and translate it into technical roadmaps and implementation plans
• Make critical technology decisions around frameworks, infrastructure, and architecture patterns that set products up for long-term success
• Write clean, maintainable code with comprehensive testing that allows for rapid iteration without sacrificing quality
• Participate in code reviews and contribute to engineering best practices across multiple codebases

What We're Looking For

• Strong computer science fundamentals with the ability to design elegant solutions to complex problems
• 3+ years of professional software development experience with a track record of shipping production systems
• Deep expertise in backend development: RESTful API design, database modeling, authentication/authorization, and performance optimization
• Experience with modern backend languages and frameworks (Python/Django/FastAPI, Node.js/Express, Go, or similar)
• Solid understanding of software design patterns, clean architecture principles, and when to apply them pragmatically
• Hands-on experience with cloud platforms and containerization technologies
• Frontend development skills with React and modern JavaScript/TypeScript
• A product-minded approach: you care about user outcomes, not just technical implementation
• Excellent communication skills with the ability to explain technical concepts to non-technical stakeholders

Nice to Haves

• Experience with AI/ML frameworks and Large Language Models (OpenAI, Anthropic, vector databases)
• Background in early-stage startups or product development agencies
• Contributions to open-source projects or technical writing
• Experience with mobile development (React Native, Flutter)
• DevOps expertise with CI/CD pipelines and infrastructure as code

Logistics & Perks

• Location: Westlake, OH. Hybrid schedule (3 days/week in office)
• Competitive compensation
• Work on diverse, cutting-edge products across multiple industries
• Direct mentorship from successful serial entrepreneurs
• Small, high-impact team where your decisions directly shape product outcomes
• Flexible PTO and comprehensive health benefits
