[Hiring] Senior Full-stack Engineer @altegio

Role Description

We’re looking for a senior engineer who enjoys solving complex problems, influences product decisions, and knows how to accelerate development with AI without compromising quality.

How We Build Software:

• We’re building an AI-first development process: almost all code is written with coding agents, including Claude Code and Codex.
• Our repository contains over 100 shared skills, an AI agent reviews changes, and deployments are triggered from Slack.
• Colleagues without an engineering background also use AI, with developers reviewing their changes.

The main challenge is navigating a large codebase, understanding business logic and edge cases, and verifying that solutions work correctly.

We need an engineer who:

• Delegates as much work as possible to AI.
• Critically evaluates AI output.
• Takes ownership of the quality of the final solution.

What You’ll Do:

• Own tasks end to end: Clarify requirements with the CTO and product team, explore code and data, and choose solutions even when there’s no detailed specification.
• Influence product decisions: Analyze user journeys and feedback, proposing solutions that account for UX, product consistency, and implementation costs.
• Ensure quality: Define acceptance criteria, plan testing and rollbacks, and cover key and edge cases with automated tests.
• Build full-stack features: Work across the stack, from UI to database, safely modify existing code, and ship small MRs behind feature flags.
• Use AI effectively: Delegate tasks to coding agents, provide the necessary context, and verify their code, tests, and results.
• Improve engineering practices: Review colleagues’ changes and turn successful approaches into shared skills, agent workflows, and automated checks.

Upcoming Product Areas:

• Developer and vibe-coding tools, including a public API, MCP server, marketplace, plugins, and embeddable modules.
• Expanding payments capabilities.

Qualifications

• Commercial development experience with PHP and Vue, React, or a similar frontend framework.
• Hands-on experience using coding agents in real-world projects.
• Strong engineering fundamentals, including transactions and concurrency, idempotency, time zones, access control and data ownership, N+1 queries, and working with tables containing millions of rows.
• The ability to identify risks, flag blockers, and propose solutions.
• English proficiency at B1 level or above.

Nice to Have

• Experience with payments, webhooks, OAuth, and public APIs.
• Experience with high-load systems and technologies such as MySQL, Redis, RabbitMQ, and ClickHouse.
• Hands-on experience with Sentry, Grafana, Kubernetes, CI/CD, and gradual rollouts.
• Experience building custom skills, coding agents, or MCP servers used by a team.

Our Tech Stack

• Backend: PHP 8.3, Slim 4, Symfony Components, RoadRunner.
• Frontend: Vue 3, TypeScript, Pinia, Vite.
• Data and infrastructure: MySQL, Redis, ClickHouse, RabbitMQ, GitLab CI/CD, Docker, Kubernetes.
• AI: Claude Code, Codex.

Our Hiring Process

• Recruiter screening — 30 minutes.
• Technical interview in two parts:
  • Without AI: Review a real engineering solution and conduct a code review of a small full-stack PR.
  • With AI: Solve a task using your preferred coding agent and discuss your workflow and how you validate the results.
• Product deep dive and leadership meeting: Work together on an ambiguous problem and discuss your decision-making approach.

What We Offer

• Competitive, market-aligned compensation.
• A product at scale: High traffic, a large customer base, and complex business logic. Your decisions will impact businesses and their customers across multiple countries.
• Real ownership and influence: Minimal bureaucracy, direct interaction with C-level leadership, and involvement in product decisions.
• A strong engineering culture: Code reviews, knowledge sharing, and open discussions about technical decisions.
• Fully remote work.
• Employment in Armenia or Kazakhstan, or a contractor arrangement through an individual entrepreneur (IE).
• Your choice of equipment: MacBook, Mac mini, Lenovo, or Dell.
