Position overview

We are seeking a Full Stack Engineer who builds with AI in the loop — both as a daily development practice and as a product capability. You are fluent with coding agents (Claude Code, Cursor, Copilot) and ship faster because of them, not despite them. You understand how to design, prompt, evaluate, and operate LLM-backed features in production — including model selection, context engineering, evals, guardrails, and cost and latency tradeoffs.

Beyond AI, you have deep Golang and React/TypeScript expertise and own features end-to-end: from understanding business requirements, through writing and testing code, to deployment and production monitoring. This role requires strong autonomy, proactive communication, and the ability to deliver reliable, scalable solutions in a modern cloud environment.

This position operates according to the CET time zone.

Responsibilities

• Design and ship LLM-powered product features: prompt design, retrieval, tool and function calling, structured outputs, streaming, evaluation harnesses, and guardrails.
• Operate AI features in production: monitor quality, latency, cost, and failure modes; iterate on prompts, models, and architectures based on real usage.
• Use AI coding tools (Claude Code, Cursor, Copilot) as a core part of your workflow to accelerate delivery without compromising code quality.
• Design, develop, and maintain backend services using Golang and frontend applications using React/TypeScript.

• Define and maintain infrastructure using Terraform and deploy services in Kubernetes clusters.
• Build and maintain CI/CD pipelines in Jenkins for automated deployments.
• Ensure high-quality code through comprehensive testing and code reviews.
• Monitor application performance and troubleshoot issues in production environments.
• Contribute to UI/UX improvements and ensure seamless integration between frontend and backend.

Requirements

• Demonstrable production experience shipping LLM-powered features. Be ready to walk through a feature you built: prompts, evaluation approach, failure modes you fixed, and how you measured success.
• Hands-on with at least one major LLM provider's API (Anthropic, OpenAI, AWS Bedrock, or equivalent), including streaming, tool use, and structured outputs.
• Daily use of AI coding assistants in your workflow; able to articulate where they help, where they hurt, and how you maintain code quality.
• Strong, in-depth knowledge of Golang.
• Experience delivering complex backend systems from design to production.
• Solid background with Kafka and event-driven architectures.
• Hands-on experience managing AWS environments.
• Proficiency with Terraform for infrastructure-as-code.
• Experience deploying and operating services in Kubernetes.
• Building CI/CD pipelines in Jenkins.
• Proven ability to ensure quality through comprehensive testing.
• Strong proficiency in React and TypeScript.
• Experience contributing to front-end features, UI components, and client-side logic.
• Ability to seamlessly integrate frontend with backend services.
• Excellent English communication skills, written and spoken.
• Self-driven and able to work independently while managing workload effectively.

Nice to have

• Experience with agent frameworks, multi-step tool-use loops, or RAG systems at scale.
• Built or maintained an evaluation pipeline (offline evals, LLM-as-judge, human review loops).
• Open-source contributions, published writing, or talks on applied AI engineering.

We're looking for an experienced Go Backend Developer to build a server-side slot game engine from scratch on a Go-based GDK. This is a 3-month freelance project with full ownership of the engine — from math model to RGS integration and certification readiness.

You'll be the game-logic authority on the project, working closely with a Game Designer, Mathematician, and Frontend Developer.

What you'll be doing

• Building the slot engine end-to-end: lifecycle interfaces (spin generation, keep-generate, history replay), win evaluation, and RGS integration contract
• Owning the game mathematics: RTP structure, reel strips, paylines / clusters / Megaways / avalanche, and probabilistic outcome modelling
• Implementing the full feature set: free spins, buy bonus, ante bet, max-win validation
• Externalizing all math configuration (reel sets, RTP, volatility, paytable) so Game Design and math can update values without code changes
• Running RTP simulation and validation harness; attaching simulation reports to each submission
• Driving builds through platform integration review and remediating findings until accepted
• Maintaining backend documentation: math/game-logic spec, config format, architecture records, README
• Actively using AI tools (Claude, ChatGPT, Gemini) to accelerate scaffolding, math modelling, and documentation — with reproducible, documented workflows

What we're looking for

• 3+ years of Go backend experience, layered service design, unit-testable game logic
• SDK lifecycle interfaces: spin, keep-generate, deterministic history replay
• Server-authoritative slot math: RTP, reel strips, paylines, Megaways, cascades, free spins, buy bonus
• All math in config — no hardcoded values; integer/fixed-point arithmetic only, no floating-point on monetary ops
• RNG exclusively via SDK-injected client

What we offer

• Strong mid-senior team — you'll work with experienced engineers, not learn on the job alone
• Real architectural influence — this is a greenfield engine, your decisions shape the product
• Flexible schedule — we care about results, not hours logged
• No micromanagement — you own your scope end-to-end and are trusted to deliver

YGO.ai is a VC-funded AI tourism platform. 
This is a hands-on senior backend role for someone who uses AI to ship fast and cares about the product, not just the code.

This is not a traditional coding role. 
You'll use Claude Code and other AI tools to multiply your output, always thinking about how the feature you're building helps the user. 
We have no QA team, so you own the quality of what you ship: everything you deliver has to work.
 

What you'll do

• Own features end to end, from spec to deployment to fixing bugs
• Use Claude Code to generate Golang backend code, then review the output for quality and architectural fit
• Fix bugs to learn the codebase, then build new features quickly
• Make fast decisions on what to build, buy or generate with AI
• Talk to customers when they report issues and ship fixes the same day
   

At Lead level, on top of the above

• Be the spokesperson for your pod, internally with product, design and leadership, and externally with clients
• Coordinate work across the pod: break initiatives down, sequence them, surface blockers

• Represent your pod in product planning and bring a strong product point of view to scoping and trade-offs

   

This is not a people-management role. 
No one-to-ones, no performance reviews, no career coaching. 
The coordination work sits on top of your engineering, not instead of it and most of your week is still spent building.
 

Our stack
Go monorepo (no framework, 3+ services), PostgreSQL, Redis, Docker Compose mirroring production, Jaeger tracing, BetterStack for logging and alerting, Redis Asynq queue. 

Claude Code is mandatory.

You must have

• An ownership mentality and a strive for simple, high-quality solutions

• Excellent spoken English and a good connection for daily video calls
• Availability full-time, in European or African time zones (±3 hours from CET)
• Willingness to do occasional on-call
   

Required at Lead level

• Multi-year experience leading a pod, squad or similar unit (a hard must)
• Comfort facilitating a pod without formal authority
• Willingness to be the external face of your pod in client meetings

Don't apply if

• You've never used Claude Code or similar AI coding tools
• You're a perfectionist who loves to code for its own sake
• You need detailed specs before starting
• You see AI as a threat rather than leverage
• You're outside European or African time zones
• You want a people-management role or to lead in name only without being hands-on

About the project

We're preparing to rebuild an inherited Go microservices codebase for an insurtech client (US market). The code was written by a previous team and handed over "as is." Before we commit to refactoring or rewriting, we need an independent technical audit from an experienced Go developer. Your report will drive the per-service decision: accept as-is, refactor, or rewrite.

Scope

Audit ~11 Go repositories (microservices + shared SDK/utils modules) across four dimensions:

1. Security — vulnerabilities, hardcoded secrets, dependencies with known CVEs, service-to-service auth.
2. Code quality — architecture, technical debt, error handling, test coverage, idiomatic Go.
3. Performance — goroutine/resource leaks, DB usage (N+1, pooling, timeouts, transactions), context handling.
4. Readiness for handover — how maintainable the code is for a new team (docs, CI/CD, migrations, bus factor).

Stack: Go 1.17 and 1.20 (both EOL — upgrade will be a separate recommendation), gRPC, Kong API Gateway, protobuf contracts, a dedicated secrets service, microservices architecture.

Toolchain: go vet, staticcheck, golangci-lint, gosec, govulncheck, osv-scanner, go test -cover -race — automated pass plus manual review of security-critical paths and architecture.

Deliverables

1. Audit report (markdown) — findings by severity (Critical/High/Medium/Low/Info), each with repo, file:line, impact, recommendation.
2. Readiness matrix per service (security / quality / tests / performance / readiness).
3. Executive summary — top risks and a strategy recommendation (accept / refactor / rewrite) per service.

You

• 5+ years of production Go.
• Real experience auditing or deep-reviewing large, unfamiliar codebases.
• Confident with Go static analyzers and vulnerability scanners.
• Solid on microservices, gRPC, and DB work.
• Write clear, prioritized reports — interpretation, not raw tool output.
• Self-directed: we provide the spec and access, you deliver without hand-holding.

Nice to have: fintech/insurtech background, EOL Go migration experience, Kong/protobuf familiarity.

About the Role

We are looking for a Lead AI-First Backend Engineer to join a product team building an AI-powered tourism platform.

This is not a traditional backend role. We don’t need someone who just writes code — we need an engineer who builds features end-to-end using AI tools, takes ownership of delivery, and ensures what gets shipped actually works.

You will use Claude Code and other agentic AI tools to significantly accelerate development while maintaining high standards of architecture, performance, and product quality.

Key Requirements (Must-Have)

• 5+ years of experience with Golang (exceptional 4+ years considered)
• Proven hands-on experience with Claude Code or similar AI coding tools (mandatory)
• Strong experience delivering backend systems in production
• Demonstrated experience leading delivery within a team (informal or formal tech lead)
• Strong English communication skills (Upper-Intermediate or higher)

What Makes This Role Different

• AI writes most of the code — you guide, review, and ship
• You are responsible for end-to-end feature delivery
• There is no QA team — you own quality completely
• This is a hands-on engineering role, not people management

What You’ll Do

• Own features end-to-end: from specification to deployment and bug fixing
• Use Claude Code to generate backend code in Golang
• Review AI-generated code for correctness, performance, and architecture
• Quickly iterate: fix issues, learn the codebase, and ship new features
• Make pragmatic decisions on what to build vs buy vs generate with AI
• Work directly with users/customers to resolve issues and ship fixes fast

Lead Responsibilities (Without People Management)

• Act as the spokesperson for your pod (engineers, product, design)
• Coordinate delivery: break down work, align priorities, remove blockers
• Represent your team in product planning and stakeholder discussions
• Contribute to product decisions and trade-offs with a strong product mindset
• Join client conversations when needed to align on requirements and delivery

👉 You remain primarily a hands-on engineer — leadership sits on top of your IC work.

Tech Environment

• Backend: Golang monorepo (multiple services, no heavy framework)
• Infrastructure: Container-based (Docker, PaaS-managed)
• Databases: PostgreSQL, Redis
• Async: Redis-based queues
• Observability: Jaeger (tracing), Betterstack (logging & alerts)
• AI Tooling: Claude Code (mandatory)

What You’ll Build

• AI-driven platform features and agent-based systems
• Backend services and APIs
• Data pipelines and integrations
• Connections to external APIs (suppliers, partners, AI providers)

You’re a Great Fit If You

• Think in features and systems, not just code
• Use AI as your primary development tool
• Can quickly identify issues in AI-generated code
• Ship fast but always validate quality
• Have led delivery in a team (even without formal title)
• Care about product impact, not just implementation

Important Notes

• This is not a people management role
• This is a high-ownership, high-speed environment
• Candidates must demonstrate real AI-first development experience
