Ready to build, improve and ship? Let’s talk!

Codebridge is looking for an Applied AI Engineer to build the AI functionality of a corporate learning platform end to end. Agents — planning, tool use, acting across the product — are the core, surrounded by retrieval, content generation, and labs. Everything is model-agnostic across Claude, OpenAI, and Gemini. 

     Responsibilities

• Design and ship agents — the core of the role: planning, tool use, memory, and guardrails, orchestrated with LangChain/LangGraph, exposed via MCP where it fits, running behind a provider-abstraction layer with model routing and cost control
• Build product features end to end — from the front end through backend services to the model call in the cloud
• Set up and tune retrieval: ingestion, chunking, retrieval quality, reranking, and grounded generation with citations
• Evolve the content-generation pipeline: grounded generation from ingested sources, structured outputs that survive provider differences, and accuracy checks that keep generated material true to source
• Develop hands-on lab environments in a sandboxed execution platform: mock APIs, auto-verification harnesses that grade learner work, and managed multi-provider model access with per-user budgets
• Take charge of evaluation infrastructure: task datasets, deterministic and model-based graders, regression suites, and cross-provider benchmarks

     Requirements

• 4+ years in software engineering, with production systems you can walk through end to end
• 1+ years shipping production LLM applications — agents, tool use, retrieval — with hands-on work across at least two of the three major platforms (Anthropic, OpenAI, Google)
• Depth in agent development: tool use, memory, multi-step orchestration, and MCP — you've built and debugged MCP servers, not just consumed them
• Claude Code as a daily working tool, plus working fluency with the OpenAI API and Gemini — or a demonstrated ability to get there fast, since the abstractions matter more than any single SDK
• Evaluation fluency: task datasets, deterministic and model-based graders, regression suites. "I tested it manually and it looked fine" is an unfinished sentence
• Solid Python for LLM tooling, with experience in LangChain/LangGraph or an equivalent orchestration framework
• Comfort with sandboxed cloud execution environments, CI, and API security basics
• Clear technical communication — you can review someone else's work rigorously and kindly, and explain a model limitation to a non-engineer without jargon
• A responsible, outcomes-focused mindset
• Advanced English or higher
  
  Nice to Have: 
• Experience with TypeScript/Node/React 
• Provider certifications (Anthropic, OpenAI, or Google Cloud AI) or demonstrable equivalent depth 
• Experience with learning platforms, developer education, or technical enablement 
• Experience with LLM gateway/routing layers, structured-output schemas across providers, or multi-model evaluation tooling 
• Public evidence of technical judgment: open-source contributions, technical writing, or talks 

     What we offer

• Technical Ownership: You own the AI architecture and the standards behind it
• Modern AI Work: Agents, retrieval and evaluation as the everyday job, not a side experiment
• Collaborative Environment: A team that values partnership, creativity, and mutual respect
• Flexible Work: Work remotely from the comfort of your home or join us in our modern Kyiv office
• Generous Time Off: 20 paid vacation days + 15 sick leave days annually
• Professional Growth: Compensation for courses, certifications, and learning resources
• Cutting-Edge Tools: Access to premium AI tools (Cursor Pro, Claude Code, GitHub Copilot, etc.)

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.
