Full Job Description

📋 Description

• As a Backend Engineer (MarTech) at Leaply, you will play a critical role in building and evolving a unified marketing technology platform that directly drives business performance by transforming fragmented tools into a cohesive, scalable system powering growth across global markets.
• You will take full ownership of five or more existing backend services—including Hokuto, UA automation, Creo Factory, Revealbot, and Creo-translate—by evaluating their current state, identifying architectural bottlenecks, and leading systematic improvements in reliability, scalability, and maintainability to support rapid business growth.
• Your day-to-day work will involve developing and maintaining production-grade integrations with Meta, TikTok, and Google Ads platforms, implementing robust error handling, rate limiting, retry mechanisms, and webhook processing to ensure silent-failure-free operations and reliable data flow.
• You will redesign the tracking architecture by migrating from client-side to server-side tracking (leveraging the CAPI pattern for Facebook and similar platforms), write comprehensive test coverage, and build intuitive tools that empower Growth Managers to independently configure and manage tracking for their marketing funnels without engineering dependency.
• You will eliminate manual operational workflows currently reliant on tools like Airtable by automating routine tasks, enabling marketing teams—including UA managers, designers, and growth leads—to operate autonomously and efficiently in campaign execution and optimization.
• Proactively, you will identify and implement emerging martech solutions before they become bottlenecks, shaping the long-term technical vision of the marketing stack and influencing product and engineering priorities through data-driven insights and systems thinking.
• You will collaborate closely with non-technical stakeholders such as UA managers, designers, and growth managers, translating business needs into technical solutions while maintaining clear communication and shared ownership of outcomes.
• The team at Leaply operates within Skelar AS, a venture builder that launches and scales international IT product companies using venture capital principles, backed by a network of experienced founders and specialized infrastructure teams.
• You will join a high-autonomy, fast-moving culture where ownership is expected—you are encouraged to identify problems, propose solutions, and drive impact without waiting for task assignment, all while leveraging AI tools to amplify your effectiveness and strategic thinking.
• In this role, you will deepen your expertise in performance marketing systems, server-side tracking, and cloud-native backend architectures while contributing directly to a business that has already achieved positive unit economics and is targeting 10x growth by year-end.
• You will gain exposure to a full venture builder ecosystem, including access to internal clubs, training programs, conferences, and a community of serial entrepreneurs, enabling both technical and professional growth beyond pure engineering.

🎯 Requirements

• 3+ years of commercial backend development experience
• Proficiency in Node.js and TypeScript as the primary technology stack
• Strong experience building reliable API integrations with error handling, rate limiting, retries, and webhook management
• Hands-on experience with GCP services such as Cloud Functions, Cloud Run, BigQuery, or Firestore
• Demonstrated systems thinking—ability to design architecture, anticipate bottlenecks, and define technical priorities independently
• High autonomy and ownership mindset—capable of identifying problems and driving solutions without PM direction
• Proven ability to collaborate effectively with non-technical teams including UA managers, designers, and growth leads
• Habitual use of AI tools to enhance productivity, decision-making, and strategic thinking in daily workflows

🏖️ Benefits

• Access to Skelar’s venture builder infrastructure, including 8 specialized support teams covering recruiting, finance, legal, and communications
• Membership in a founder community with experience launching multiple successful businesses, offering mentorship and peer learning
• Participation in internal professional clubs (marketing, development, finance, recruiting, brand ambassadorship) for cross-functional growth
• Opportunities for training, courses, and conference attendance to support continuous learning
• Health insurance provided as part of the compensation package
