Stark builds the world’s most powerful electric motorcycles. From the VARG MX to the road-legal VARG EX & SM, our bikes have won world championships and are engineered to outperform anything with a combustion engine.
We’re based in Sant Boi, Barcelona, growing fast (77% year-on-year), and building a team that will take us even further. If you want to work on a product that people are genuinely obsessed with, this is it.
Stark will become the global market leader in premium motorcycles. Building premium motorcycles requires innovation and we need your help to make us succeed in building the backend for our AI systems.
Our mission is to lead the way towards a sustainable motorcycle industry, by reducing plastic and CO2 pollution.
This will be achieved by building sustainable products that are superior to traditional technology in terms of Performance, Emotion and Design.
The Engineering Manager — Web owns the delivery and technical health of both the Frontend and Backend web teams. This is a hands-on leadership role: the EM drives product and project management, triages and fixes bugs, and makes anything happen that the business needs from its web stack. The primary domain is e-commerce, but the scope extends to any web-related challenge that surfaces across the company—from payment integrations and order workflows to internal tooling and data pipelines.
We need a technical leader who has shipped and scaled high-volume e-commerce systems, can context-switch between frontend and backend problems daily, and brings enough DevOps fluency to keep the infrastructure running while the teams build. The right person combines deep JavaScript expertise with solid Python knowledge and the operational instinct to unblock teams fast.
Team & Delivery Leadership:
Manage and grow the Frontend and Backend web engineering teams: hiring, 1:1s, career development, performance reviews.
Own sprint planning, prioritization, and day-to-day project management across both teams.
Be the single point of accountability for getting things shipped—coordinate across design, product, QA, and external vendors as needed.
Step in personally to unblock critical issues: debug production incidents, write code, review PRs.
E-Commerce & Web Platform:
Drive the architecture, reliability, and evolution of the e-commerce platform (catalog, cart, checkout, payments, order management).
Own integrations with payment providers, ERP systems, and third-party services.
Ensure the platform handles high-volume traffic and transaction spikes without degradation.
Identify and resolve performance bottlenecks across the full stack.
Technical Ownership:
Maintain high code quality standards through code reviews, testing practices, and CI/CD pipelines.
Make pragmatic architectural decisions that balance speed of delivery with long-term maintainability.
Manage cloud infrastructure and deployments (AWS); handle DevOps tasks including monitoring, alerting, and incident response.
Keep the security posture strong—WAF configuration, dependency management, access controls.
AI & Tooling:
Drive adoption of AI-assisted development tools (Claude, Cursor, Copilot) across both teams to accelerate delivery and code quality.
Continuously evaluate emerging AI tools and integrate them into the development workflow where they add real value.
Cross-Functional Problem Solving:
Act as the go-to technical resource for any web-related need that arises across the company.
Build internal tools, dashboards, and automations when they solve real problems.
Collaborate closely with the IT Director to align web team priorities with company-wide technology strategy.
Authority to define technical standards, tooling, and workflows for both web teams.
Decision-making power over sprint priorities and resource allocation within the web engineering scope.
Direct access to company leadership for fast escalation and alignment on business-critical issues.
Freedom to evaluate and adopt new technologies, frameworks, and services that improve delivery or platform performance.
Authority to propose and drive process improvements across the web development lifecycle.
Must have:
5+ years of professional software engineering experience, with at least 2 years managing engineering teams.
Deep proficiency in JavaScript/TypeScript across both frontend (React, Next.js, or equivalent) and backend (Node.js, Express, or equivalent).
Proven experience building and scaling e-commerce platforms with high transaction volumes.
Solid Python knowledge for scripting, automation, data processing, or backend services.
Working DevOps skills: CI/CD pipelines, AWS services (EC2, ECS, Lambda, S3, CloudFront, RDS), containerization, monitoring.
Experience with payment gateway integrations and order management workflows.
Track record of managing both product and project delivery—not just technical execution.
Hands-on experience with AI-assisted development tools (Claude, Cursor, GitHub Copilot, or similar) and a clear vision for integrating AI into engineering workflows.
Strong communication skills in English, both written and verbal.
Nice to have:
Experience with headless commerce architectures or composable commerce stacks.
Familiarity with ERP integrations (SAP, NetSuite, or similar).
Experience with infrastructure-as-code (Terraform, CloudFormation).
Background in B2B and B2C e-commerce models.
Knowledge of web security best practices and WAF management.
Experience working in a fast-growing, scaling company.
