About Everfit

At Everfit, we're on a mission to build the future of personalized fitness. We connect coaches and clients seamlessly through a global wellness marketplace where anyone can find the perfect coach - regardless of budget, goals or location. With nearly 280,000 coaches in 200+ countries, our platform supports not only personal trainers, but Olympic athletes, military trainers, celebrity coaches, cancer rehab specialists, and everyday heroes transforming lives through fitness. We're not just helping people get stronger—we're helping coaches build thriving businesses that make a real impact.

From workouts and nutrition to habit coaching, payments, and client communication, Everfit brings it all together with a powerful layer of automation to help coaches scale their impact and grow their business. We're integrating next-gen AI sidekicks - smart assistants that help coaches program and unlock deep health insights in real time. Imagine if Jarvis from Iron Man doubled as your personal fitness strategist!

Position Overview:

We are looking for a Tech Lead to anchor the technical direction of Everfit's Core squad, the most used, most business-critical part of our platform.

This is primarily a technical leadership role. Roughly 80% of your time will be on technical direction, architecture decisions, system design, code reviews, and mentoring engineers across Core's sub-squads. Around 20% will be hands-on coding, focused on the most complex and highest-stakes parts of the system.

What makes this role unique is breadth. Core's teams span backend, frontend, mobile, and DevOps, and you'll need to provide meaningful technical oversight across all of them. You don't need to be an expert in every discipline, but you should be fluent enough to guide architecture decisions, challenge technical trade-offs, and earn the trust of engineers regardless of their stack. Your primary depth is backend — that's where the hardest system design problems live. But your awareness of how mobile, frontend, and DevOps connect to the backend is what makes you effective as the technical anchor for Core.

We operate with an AI-first engineering mindset. You'll champion AI tools across the squad, helping engineers move faster, write better code, and ship with more confidence. We're also building AI features into the Core product itself, so you'll help shape how AI integrates with the coaching workflows coaches rely on every day.

Your impact

Technical Direction & Architecture

• Own the architectural patterns and technical standards for Core's backend systems — workout programming engines, scheduling logic, nutrition tracking, multi-tenant platform infrastructure, notification pipelines, and third-party integrations.
• Drive solution design for complex features: new product areas, cross-squad integrations, platform-level changes, and performance-critical systems.
• Make architectural decisions that balance delivery velocity with long-term maintainability — Core is a high-frequency product and tech debt accumulates fast.
• Define and uphold engineering standards across all six Core sub-squads: API design, data modeling, testing practices, code review culture, and documentation.
• Proactively identify and lead reduction of technical debt in coordination with Engineering Management and Product.

Hands-on Engineering (~20%)

• Stay in the code on the most critical work — core platform infrastructure, high-risk migrations, cross-squad technical foundations, and architectural proof-of-concepts.
• Review pull requests across sub-squads with depth and speed, giving feedback that helps engineers grow — not just ships.
• Set the standard for what good code looks like across Core: observable, testable, maintainable, and scalable.

AI-First Engineering

• Champion AI-assisted development across all Core sub-squads — from code generation and test writing to automated documentation and PR reviews.
• Collaborate with the AI squad on integrating AI features directly into Core workflows: smart programming suggestions, automated progress summaries, AI-powered onboarding.
• Help engineers build practical AI fluency through pairing, demos, and shared tooling workflows.

Mentorship & Team Growth

• Mentor and coach engineers across Core sub-squads — raising the technical bar through code reviews, architectural guidance, and technical pairing.
• Run regular technical discussions and design reviews that help engineers grow as system thinkers, not just feature builders.
• Contribute to hiring across Core: design technical assessments and conduct engineering interviews calibrated to the Core domain.

Cross-functional Collaboration

• Be the primary technical voice in product discovery across Core — shaping what's feasible, what's scalable, and what will cause pain six months from now.
• Partner closely with Core PMs, BAs, QA Lead, and Design to ensure technical decisions translate cleanly into user-facing product quality.
• Align with Tech Leads in other squads (Marketplace, Payment, AI) on shared infrastructure, platform standards, and cross-squad integrations.
• Represent Core Engineering in cross-functional leadership discussions, communicating system decisions with clarity to non-technical stakeholders.

Yêu cầu công việc

Must-Have

• 5+ years of software engineering experience with a strong backend foundation, plus 2+ years in a Tech Lead, Senior Lead, or equivalent technical leadership role.
• Deep backend expertise: system architecture, API design, data modeling, async and event-driven processing, performance optimization, and distributed systems.
• Solid understanding of frontend engineering (React or similar) — enough to review architecture decisions, guide performance trade-offs, and provide meaningful technical direction to FE engineers.
• Solid understanding of mobile engineering (iOS or cross-platform) — enough to assess architectural quality, review technical decisions, and collaborate effectively with mobile engineers.
• Comfortable with DevOps fundamentals — CI/CD pipelines, containerization, cloud infrastructure (AWS preferred), and deployment practices — so you can oversee and guide the full delivery lifecycle.
• Experience building or scaling complex SaaS products with multiple feature areas — ideally platforms with high user frequency and diverse product surfaces (scheduling, tracking, integrations, notifications).
• Proven ability to set and uphold engineering standards across a cross-discipline team — not just within a single stack.
• Excellent English communication skills — able to lead technical discussions, write clear architectural decisions, and align non-technical stakeholders on trade-offs.
• High ownership mindset: you take problems end-to-end, proactively surface risks, and drive them to resolution.
• AI-first engineering mindset: you actively use AI tools to work smarter and help your team do the same.

Nice to Have

• Hands-on production experience across multiple disciplines — shipped both backend and mobile or frontend features in the same product.
• Familiarity with our stack: Node.js, MongoDB, PostgreSQL, AWS, Docker, React.js, iOS (Swift) — or equivalent experience with comparable technologies.
• Experience building domain-specific engines: scheduling systems, rule engines, workflow automation, or data-heavy tracking features.
• Background in fitness tech, health tech, coaching tools, or any high-frequency B2B SaaS product.
• Experience working with distributed engineering teams across Vietnam, US, or UK time zones.
• Hands-on exposure to AI feature integration — LLM-powered suggestions, AI-assisted workflows, or personalization systems.
