At Core, we are fundamentally reshaping the fitness landscape by moving away from traditional studio models toward an instructor-first, virtual-first future. We believe that current digital fitness options often overlook diverse communities and specific consumer needs. Our mission is to empower instructors to reach their students through a platform that celebrates a wide variety of styles and backgrounds. By breaking down barriers and stereotypes, we are working to make wellness more accessible and inclusive for everyone. As a venture-backed startup, we are currently in the early stages of product development and are looking for passionate builders to help us launch our MVP and define our engineering culture.
The role
We are seeking a Senior Tech Lead Software Engineer with a strong focus on the frontend to join our team on a full-time basis. This is a senior-level position perfect for someone who thrives in early-stage environments and wants to be one of the first engineering hires. You will work in a hybrid capacity, helping us build and scale our platform from the ground up while shaping the technical direction of our product.
Core responsibilities
- Design and implement exceptional user experiences for both fitness instructors and their students across desktop and mobile web platforms, including Progressive Web Apps.
- Lead the development of our web strategy and embeddable components using Svelte, ensuring our technical architecture is both robust and flexible enough to iterate quickly based on user feedback.
- Collaborate closely with cross-functional partners to evaluate technical tradeoffs, translate ideas into reality, and maintain high-quality code standards throughout our product lifecycle.
Skills and experience
To be successful in this role, you should possess a deep understanding of frontend fundamentals and a proven track record of delivering high-quality software. We value candidates who bring:
- Expertise in frontend development with a willingness to work across the stack on APIs and backend systems when necessary.
- Experience working within agile teams at either high-growth startups or established technology companies.
- A self-starting mindset characterized by curiosity, empathy, and a collaborative spirit.
- Bonus points for familiarity with MobX, Elixir, Flutter, or experience building with video technologies and two-sided marketplaces.
- Fluency in English.
Compensation and benefits
We believe in rewarding our early team members for their commitment and impact. This role offers a salary range of $130,000.00 to $180,000.00 per year, along with significant, competitive equity. Our benefits package includes:
- Comprehensive medical, dental, and vision insurance, with 100% of premiums covered for employees and 90% for dependents.
- A 401k retirement plan.
- A flexible hybrid work environment.
