Must-have

• Strong commercial iOS experience with Swift and UIKit.
• Experience with real production mobile applications.
• Ability to own iOS feature delivery end-to-end: app logic, UI flow, API integration, edge cases, debugging, and release preparation.
• Experience working with legacy code: refactoring, stabilizing, debugging, improving performance, and shipping without unnecessary rewrites.
• Strong understanding of REST APIs, mobile/backend integration patterns, auth flows, error handling, retries, caching, and release impact.
• Ability to think about API as a contract between backend and mobile app: data structure, required/optional fields, error states, backward compatibility, edge cases, and expected app behavior.
• Real backend hands-on experience. You do not need to be a backend specialist, but you must have written or changed server-side logic, APIs, scripts, services, or backend-adjacent functionality in a production or production-like environment.
• Strong engineering ownership: you clarify requirements, understand dependencies, surface risks, communicate trade-offs, and drive features to production-ready state.
• Practical AI-native engineering workflow with tools like Claude, Cursor, Copilot, ChatGPT, or agentic systems — with the judgment to verify, review, and own the output.
• Ability to work in a startup environment with changing priorities, imperfect systems, and high responsibility.
• Fluent Russian for team collaboration and professional English for documentation, product discussions, and technical materials.

Nice to have

• Experience with Drupal, PHP, Pantheon, or similar CMS/API backend stacks.
• Experience with Firebase Remote Config, feature flags, environment configuration, or experiment configuration.
• Experience with AI integrations, LLM-powered features, AI coach flows, voice AI, chat-like products, or near-real-time user interactions.
• Experience with Amplitude, event tracking, product analytics, or funnel debugging.
• Experience with CI/CD for iOS: Fastlane, GitHub Actions, GitLab CI, automated builds, or release pipelines.
• Experience with backend infrastructure concepts: MariaDB, Redis, Solr, Varnish, caching layers, queues, or monitoring.
• Experience in EdTech, gamified products, rewards, learning products, career development products, or engagement-driven mobile products.
• Experience working as the main mobile engineer or mobile owner in a small product team.

You will fit well if

• You are a strong iOS/mobile engineer who wants broader ownership.
• You enjoy building real product features, not just isolated technical tasks.
• You are comfortable working across mobile, backend, configuration, QA, and release boundaries.
• You can work with legacy systems without getting stuck in frustration or endless rewrites.
• You use AI tools seriously and practically — not as a shortcut around engineering expertise, but as a multiplier on top of it.

What you will get

• A core role in a small AI-native team with high trust, high responsibility, and direct product impact.
• Hands-on experience with AI-native engineering: agentic workflows, AI-assisted development, and company-level AI tooling applied to a real production product — not a greenfield demo. Building this expertise inside a real product will give you a strong competitive advantage as an engineer.
• Remote-first, async-friendly work: we keep meetings to a minimum, rely on clear written communication, and trust people to work in a way that helps them do their best work.
• Competitive salary.

Compensation: competitive, based on seniority, relevant experience, and contract setup. Salary/rate range will be shared with selected candidates before the first interview, in line with applicable pay transparency requirements.
