About project:

Backend development for mobile and web projects

SKELAR is a venture builder that builds international IT product companies according to the rules of the venture capital world. Together with our co-founders, we assemble strong teams to launch tech businesses and win in global markets.

We are currently looking for a Backend Engineer (MarTech).

We are Leaply, an ecosystem of digital and physical products designed to help people build healthy habits and improve their quality of life. We operate in global markets - the US, Tier 1, Europe, and beyond.

In June 2024, we launched an app focused on habit-building, using a subscription-based monetization model and a performance-first marketing approach (Meta, Google, TikTok). Within the first two months, we achieved positive unit economics and are now on track to grow 10x by the end of the year.

Our team is building its third business together, with successful exits behind us and a deep understanding of our niche and target audience. We move fast, communicate openly, and set ambitious goals.

What you’ll do:
— Build and evolve a unified marketing technology platform — not just a collection of tools, but a cohesive system that directly drives business performance;

— Take full ownership of 5+ existing services (Hokuto, UA automation, Creo Factory, Revealbot, Creo-translate): evaluate their current state, identify architectural bottlenecks, and systematically improve reliability, scalability, and maintainability;

— Develop and maintain production-grade integrations with Meta / TikTok / Google — ensuring robust error handling, rate limiting, retries, and clear monitoring so the system operates reliably without silent failures;

— Redesign the tracking architecture by shifting from client-side to server-side (CAPI pattern for Facebook and similar platforms), implement proper test coverage, and build tools that allow Growth Managers to independently configure tracking for their funnels;

— Eliminate manual operational workflows (e.g., in Airtable) and enable marketing teams (UA managers, designers, growth managers) to operate independently without engineering support for routine tasks;

— Proactively identify and implement new martech solutions before they become bottlenecks - shaping the long-term vision of the domain and driving technical and product priorities.

This role is for you if...

Must-have

— 3+ years of commercial backend development experience;

— Node.js / TypeScript as the main stack;

— Strong experience building reliable API integrations — including error handling, rate limiting, retries, and webhooks;

— GCP experience — Cloud Functions, Cloud Run, BigQuery, Firestore, or similar cloud environments;

— Systems thinking — able to see the system beyond individual tasks; independently designs architecture and defines development priorities;

— High level of autonomy — does not require a PM to define tasks; identifies problems and proposes solutions independently;

— Ability to collaborate with non-technical stakeholders — UA managers, designers, growth managers;

— Ownership mindset — proactively identifies risks, drives solutions, and thinks in terms of business impact;

— Uses AI as part of their workflow to move faster and think broader.

Nice-to-have

— Experience with Meta Business SDK / TikTok Marketing API / Google Ads API;

— Understanding of performance marketing — ROAS, CAPI, pixels, attribution;

— Experience building server-side tracking (e.g., Facebook CAPI or similar);

— Experience with marketing automation tools (Airtable automations, Make/Zapier, or custom solutions);

— Experience working on B2C subscription products with aggressive performance marketing.

SKELAR is an environment for self-realization of people who are able to create successful companies. We call such companies the next big everything. We believe in their power and scale.

To do this, we have created all the opportunities within our venture builder:

— 8 infrastructure teams that help businesses close any issues: from recruiting and communications to finance and legal issues;
— A community of founders who have already launched more than one business and can share practical experience;
— Internal clubs by professional areas: marketing, development, finance, recruiting, brand ambassadorship;
— Trainings, courses, attending conferences;
— Health insurance.

3-month project with possible continuation.

The project is a business platform consisting of 2 mobile apps, 2 web interfaces and admin dashboards for cleaning-on-demand and their back office.

Development from scratch, in a team of 7 developers. Your primary focus will be the development of server-side logic, working with AWS, and the creation of endpoints to serve front-end tasks.

Urgent position, start ASAP.
