Job Description
Senior Backend Engineer
Hostinger
Role Description Do you love building things that actually ship - not sitting in meetings about shipping? This job might be for you. We're looking for a generalist who's comfortable across the stack - backend, data pipeline, background jobs, and the occasional frontend change. You'll work closely with the CTO and product team to ship features fast, with fewer meetings and more doing. Your day-to-day - Build and maintain backend features: - APIs, background jobs, integrations. Our stack is Ruby on Rails but if you're strong in Python or TypeScript and willing to learn, that works too. - Improve and maintain our data pipeline: - Write reports and queries in PostgreSQL and BigQuery to keep affiliate data (clicks, conversions, commissions, payouts) correct and up to date. - Build internal dashboards and reports: - Payout summaries, revenue attribution, cohort breakdowns, etc. - Fix performance issues: - Bad queries, slow background jobs, bottlenecks. Keep things running well under load. - Use AI tools (Claude Code, Cursor) daily to move faster. We care about what you ship, not how many hours you sit. - Work async with a small team: - Few meetings, lots of ownership. You ship it, you monitor it. - Jump in on technical support: - We rotate who handles deeper technical help for our CX team - running custom scripts, debugging client-specific issues, or digging into the data when something looks off. Qualifications - 5+ years of backend engineering experience, with strong proficiency in Ruby on Rails, or solid Python/TypeScript skills with a genuine willingness to learn our stack. - Strong SQL skills, including writing complex queries, optimizing slow queries, and working with both PostgreSQL and BigQuery in production environments. - Experience building and maintaining REST APIs and background job systems (e.g., Sidekiq, Celery, or similar), with an understanding of reliability, retries, and failure handling. - Experience building internal tooling and dashboards - revenue reports, payout summaries, cohort analyses, or similar business-facing data products, ideally tied to financial or affiliate data. - Async-first, high-ownership work style - comfortable communicating through written updates, making independent decisions, and taking full responsibility for features from build through monitoring. - Practical experience using AI-assisted development tools (such as Cursor, Claude Code, GitHub Copilot, or similar) as a regular part of the development workflow to increase output quality and speed. Requirements - Data or analytics engineering background - prior work with data pipelines, event tracking, affiliate/conversion data, or analytics engineering is a meaningful differentiator for this role. - Familiarity with dbt (data build tool) for building and maintaining data transformation models, or a strong desire to learn it quickly in the context of analytics and reporting. Benefits - Real impact: High-impact ownership in a small team working closely with leadership - your work is visible, directly shapes growth. You influence decisions and priorities, not just execute tasks. - Growth ownership: High autonomy over your domain, with the trust and resources to execute well. - Flexibility: Remote-first setup - work where and how you’re most effective. - Growth support: Real room to grow, with a learning budget to improve execution. - Flat structure: Direct access to decision-makers, and the ability to influence direction without layers of approval.
