We’re hiring a Senior Software Engineer with strong architectural instincts, clean coding practices, and previous experience working in a startup environment.

You’ll be responsible for building modern backend systems (approx. 70% of your time), while also contributing to a React-based frontend (approx. 30%). You should be comfortable owning features end-to-end and thrive in the fast, iterative, and sometimes ambiguous nature of early-stage startups.

This role is for someone who’s done this before—who has helped a product go from zero to scalable, who embraces uncertainty, and who builds with both today and tomorrow in mind.

Key Responsibilities

• Design and implement scalable backend microservices using modern best practices
• Architect robust, maintainable codebases with clean design and naming conventions
• Develop and improve APIs that power personalized commerce experiences
• Use modern AI/LLM tools to supercharge your development workflow
• Implement frontend functionality using React as needed
• Own feature delivery end-to-end, from backend logic to frontend polish
• Participate in architecture discussions and guide system design
• Write clean, test-driven code and contribute to engineering documentation
• Help shape and enforce engineering best practices
• Work directly with a tight-knit startup team where your decisions have visible impact

Requirements

• Bachelor's degree with honors
• 7+ years of professional SW engineering industry experience
• Previous experience at a startup, ideally in early-stage or growth environments
• Strong backend development skills with OO Python. Not just scripting
• Solid React and modern JavaScript experience. 
• Comfortable architecting and building systems from scratch
• Fluent in core web concepts: HTTP, APIs, data flows, typing systems
• Experienced with SQL and database design for both OLTP and OLAP systems
• Familiar with modern DevOps or cloud deployment practices
• Passionate about test-driven development and clean code
• Able to work independently in a fast-paced, changing environment
• Clear communication skills and a collaborative mindset

Bonus Points For

• Shopify or e-commerce platform experience
• Prior use of LLMs or generative AI in your dev workflow
• Exposure to complex system design and scalable architecture
• Experience writing unit/integration tests and working in CI environments
• Building systems that support enterprise-level scale

Why This Role Is Different

• Early-stage impact: You’re not maintaining a legacy system—you’re helping build the future of the company.
• Startup agility: Move fast, experiment, and iterate with a team that values shipping well-designed code.
• AI + commerce: Work at the intersection of personalization, machine learning, and real-world business value.
