Job Description

Senior Backend Engineer

Hostinger International

• 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.

Job Requirements

  • 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.

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.

• Operate as a product engineer focused on solving real user and business problems, not clearing a backlog. You bring ideas, challenge assumptions, and own outcomes. • Work in an AI-first development flow. Use tools like OpenAI Codex and GitHub Copilot not just to go faster, but to do more: explore multiple approaches, validate ideas quickly, and build things that previously wouldn't have been worth the effort. • Primarily focused on backend: designing, developing, and maintaining scalable services with .NET 10, ASP.NET Core, and GraphQL. Comfortable stepping into front-end work when the problem calls for it, since AI-assisted development means you don't need to be a specialist to ship quality UI. • You're aligned to a product team and typically work alongside one or two other engineers on any given project, pairing on tough problems, reviewing each other's work, and shipping together rather than in parallel. • Uphold a high quality bar. Engineers write their own tests at the unit, integration, and end-to-end levels, and every line of code, human-written or AI-assisted, is reviewed by a human before it ships. • Drive technical improvements across the codebase. Proactively identify friction, propose changes, and see them through to adoption. Be a first responder for production. Use DataDog, Grafana, OpenTelemetry, and Microsoft Azure to quickly diagnose incidents, minimize impact, and harden the system against recurrence.
