Why Phoenix Games?

You'll join an international engineering team building products from scratch with modern technologies—without legacy code or unnecessary bureaucracy. We value clean architecture, ownership, continuous learning, and engineers who love creating impactful software.

If you're passionate about full-stack development, AI, and building scalable products, we'd love to hear from you.

About the role

ClassOwl is a school-management system used by educational institutions. We are hiring a Middle+/Senior PHP Full-Stack Developer to join the team and work on our existing product.

The application is built on a custom PHP framework. Most tasks involve extending and improving the current application: adding product functionality, changing web interfaces, maintaining APIs and integrations, and investigating issues reported from staging or production.

The developer will work across backend and frontend parts of a feature. It is important to understand an existing codebase, make changes carefully, and consider how they affect different school installations. We expect the person to take part in a feature from clarification and estimation to implementation and code review.
 

What you will work with

• backend and frontend features in an existing PHP application
• vanilla JavaScript, HTML, CSS, jQuery — not a React/Vue SPA
• MySQL and SQL queries
• REST APIs used by the mobile application
• third-party integrations
• debugging and fixing issues in staging and production
   

Responsibilities

• clarify requirements together with the Business Analyst, asking questions that help narrow down scope where needed
• estimate tasks and discuss solutions with the Lead Developer, considering the impact across different school installations
• review code from other developers and give constructive feedback
• maintain and extend REST APIs used by the mobile application
• integrate and maintain third-party services
• investigate and fix bugs reported by QA, Customer Support, and from staging/production
• write and optimize SQL queries for new and existing functionality
   

What we expect

• 4+ years of PHP web-development experience, including backend and frontend work
• strong knowledge of PHP, vanilla JavaScript, HTML, CSS, and MySQL
• experience writing and optimizing SQL queries
• experience working with an existing (legacy/production) codebase
• ability to work with REST APIs and third-party integrations
• Git and Linux experience
• English at B1 level or higher
   

Terms of cooperation

We offer two cooperation formats to choose from ФОП (standard) and ФОП+ (an extended package with paid vacation, bonuses, and additional compensations). Details of each format are discussed during the interview.

Forest AI

## Start: ASAP

Full time preferred, four days works, three is possible. Freelance, permanent or B2B: your choice (freelance day rate discussed separately).

The best developers are now part product manager and part project manager of their own army of AI coding agents. Their job is making sure those agents deliver what the business actually needs, not just what someone wrote in a ticket. In that world the bottleneck isn't producing correct code. It's understanding the business and communicating clearly.

We work Claude Code first. If you don't believe in delivering that way, this isn't the right fit.
 

## About Forest AI

Forest AI helps companies become benchmark-driven in how they build AI agents. AI agent development demands an order of magnitude more testing before release than traditional deterministic software. We build the automated evaluation and testing layer that makes testing at that volume practical, so our customers can put AI into production in places where being wrong is expensive.

## What you'll actually work on 

Your first engagement is with a German insurance venture (name shared in conversation) building an AI-driven B2C insurance value chain, quote, consult and purchase, all AI-driven, going live. There is a second track automating their internal insurance operations. It runs like a startup: decisions in-house, no corporate approval loops, ideas become working software the same day.
 

## The role

100% hands-on. You take a vague business need, turn it into a system that works, and keep it working, owning the why, the build and the test without depending on someone else for the biggest chunk of it.
 

• - Pick up signal fast. Hear one sentence mid-meeting, recognise it carries real information about what the business needs, work out what the speaker actually wants, and go deliver it.
  
  - Own outcomes to completion. We drop you into a project, say "automate this manual customer workflow," and three months later it just works, without anyone directing every detail.
  
  - Own customer satisfaction. If the customer doesn't see the ROI, the software gets thrown out. Everyone here writes down why a feature matters to the customer. Sometimes that lands in a presentation. When it doesn't, it lands in the commit message.
  
  - Push the business for clarity. Press for decisions where the right AI behaviour can't be intuited, or where the data to decide it doesn't exist yet.
   

## How we build

TypeScript end to end. Next.js and React on the front, Postgres on Supabase, AWS underneath, an agent framework (we use Mastra, any comparable one is fine), and Langfuse for tracing and evaluation.

Claude Code is the primary build tool, not an accessory. That's the part we care about most.

The specific tools matter far less than how quickly you become productive with them. If you've shipped serious software in another stack and you steer AI agents well, you're in scope.
 

## What we're looking for
 

• 
  - Based in Estonia.
  
  - Several years building and running production software real customers depend on: APIs, backend services, data pipelines, and the operational reality of keeping them up.
  
  - A track record of owning a customer-facing build from zero to production, ideally more than once.
  
  - AI-native, hard requirement. Claude Code or Codex as your daily driver.
  
  - Roughly a year of real, hands-on exposure to building LLM-based features in production. Nobody has five years of it. Claiming so is a red flag.
  
  - Strong discipline around automated testing, CI/CD and monitoring. Evaluation and testing are our product, so this matters more here than in most places.
  
  - Real customer-facing time: consulting, forward deployed engineering, founding your own company, or an in-house role where you sat with the business. You've run requirements conversations and can separate the requests that genuinely drive return from the wishes and curiosities that arrive alongside them.

  
  - Pragmatic, solutions-first. No "not in my ticket" reflexes.
  
  - Working language is English. German is a plus, not a requirement. A significant share of the data you'll work with is in German.

Meet the YozmaTech

YozmaTech isn’t just another tech company – we’re a global team of go-getters, innovators, and A-players helping startups and product companies scale smarter and faster. We build dedicated development teams across 10+ countries, creating strong, long-term partnerships based on trust, transparency, and real impact. Here, every idea counts. We value people who are proactive, open-minded, and ready to grow. If you’re passionate about building meaningful products and want to join a team that feels like family – you’ll feel right at home with us.

We are looking for a Senior Full-Stack Engineer who can independently own the migration of a legacy portal end-to-end. The engagement is short-term, for 3–4 months.

Our client a dedicated modernization track, not a feature squad. We're rebuilding a large EV-charging back-office portal from a legacy stack onto React 18 + TypeScript, and we want it done fast. You take a legacy screen and own the whole path to its replacement: reverse-engineering what the old flow actually does, designing and building the BFF endpoint behind it, and shipping the new page.
The Team
Small and lean – a couple of developers on the same migration, plus QA. Minimal process, minimal handoffs. There is no PM writing you specs for the screens you replace: the legacy system is the spec, and you're expected to read it

Key Requirements:
🔹 8+ years of frontend development in production environments;
🔹 5+ years with React (v18; v19 a bonus);
🔹 Strong TypeScript, JavaScript, SCSS/Sass;
🔹 5+ Java/Kotlin, Spring Boot codebase – reading it and building BFF endpoints in it (you won't own core backend services);
🔹 Redux Toolkit, Thunk, RTK Query;
🔹 MUI, Vite, CSS Modules, Storybook;
🔹 Proven full ownership of features and flows – you scope, decide and ship without being managed through it;
🔹 Ability to reverse-engineer an unfamiliar codebase: trace a flow end to end, read backend code and SQL, and find the hidden branch nobody remembers;
🔹 Comfortable working in a Java/Kotlin, Spring Boot codebase – reading it and building BFF endpoints in it (you won't own core backend services);
🔹 Solid understanding of frontend architecture, design patterns and performance at scale;
🔹 Experience building or maintaining a shared component library;
🔹 English – Upper-Intermediate or higher.

Will be plus:
🔹 Experience on a large legacy migration / modernization project;
🔹 Familiarity with CI/CD pipelines, Docker, deployment workflows;
🔹 UI testing frameworks;
🔹 Experience with AI coding agents / CLI tools (Claude Code, Cursor, Copilot) – we use them daily;


What you will do:
🔹 Own migrations end-to-end: legacy flow → API contract → BFF endpoint → new page;
🔹 Establish what a legacy screen really does – the undocumented branches, the permission gates, the edge cases operators rely on – by reading code and data, not by asking around;
🔹 Build and extend the BFF layer (Java/Kotlin + Spring Boot): endpoints, response shapes, permission gates;
🔹 Build and contribute reusable components to our shared UIkit library;
🔹 Make the architectural calls on your own pages, and review the other migration developers' work;

What you're walking into:
🔹 Two portals live side by side. New pages are feature-flag gated and embedded next to legacy screens in iframes; navigation, state and deep links cross that boundary via postMessage. Coexistence, not a clean rewrite;
🔹 The legacy system is the requirements doc. 10+ years of accumulated behaviour, largely undocumented, partly dead code. Distinguishing intended behaviour from accident is the daily job;
🔹 A monolith at the other end of your BFF. Its own conventions – failure bodies returned with HTTP 200, inconsistent payload shapes, queries older than the framework you're wrapping them in;
🔹 Multi-tenant and permission-dense. Every page, tab and dropdown is gated per service provider and per role. An empty filter is usually a 403, not a rendering bug;
🔹 Real scale in the data layer. Large grids, virtualized infinite selects, look-ahead pagination, async exports. Render performance is a design constraint, not a polish pass;
🔹 Parity with the screen you replace. Operators live in these pages all day; a dropped seconds field in a timestamp comes back as a bug report;
🔹 Debt in the new repo too. Pre-existing type errors, lint noise, half-migrated patterns. Leave things better; don't declare bankruptcy;

Interview stages:
🔹 HR-interview;
🔹 Technical interview with client;
🔹 Reference check;
🔹 Offer;

Why Join Us?

Ready to build something meaningful?

Let’s talk. Your next big adventure might just start here.

Our client: US product company, an athletics management platform used by thousands of schools across the United States: rosters, eligibility, scheduling, officials assignment and payments. A mature product with real scale, now adding AI features to the core workflows.

You will own features end to end, across the stack, in a small team where what you ship reaches production the same week.

Format and time zone

Fully remote from Ukraine. The team is distributed across US time zones, with its core on US Central Time. We ask for a few core overlap hours daily, in practice from around 16:00-17:00 Kyiv time. Everything else is asynchronous and written by default, with a low meeting load.

What you'll do

• Build user-facing features in Node.js/Express and React with TypeScript, from spec to production
• Own the full slice: API design, database schema changes, rollout and the monitoring that follows
• Work AI-first every day: funded frontier models from Anthropic and OpenAI, agentic coding tools, and repo-level convention files so generated code follows the team's patterns. The tools are used hard, the output is reviewed by humans, and PRs say what was generated
• Bring your own practice to the team: custom skills, project conventions, prompts and workflows that make the whole team faster, not just you
• Raise engineering standards through code review, architectural patterns and targeted refactors
• Support what you ship on a light shared on-call rotation

Requirements:

• 5+ years shipping production software as a full-stack engineer
• Strong Node.js with Express (or NestJS) and React, both in TypeScript
• PostgreSQL: schema design, migrations, query optimisation
• Working knowledge of AWS (ECS/Lambda, Secrets Manager, CloudWatch) and CI/CD in GitHub Actions
• Daily, hands-on use of AI coding tools (Claude Code, Cursor, Copilot or similar). Not occasional autocomplete, but agentic workflows, custom skills that encode project conventions, and the judgement to tell genuinely good generated code from code that merely looks plausible
• Comfortable owning a feature alone, from database to UI
• English B2+ 

Nice to have

• Angular, for the parts of the platform built on it
• MCP servers, custom agent skills or other tooling you built around AI-assisted development
• React Native
• Domain experience in scheduling or logistics
