Overview

We are looking for a Lead Full-Stack Engineer with a passion for creative game design and systems engineering. You won’t just be pulling tickets from a backlog: you’ll be the technical authority for our products. You will lead two completely different engineering ecosystems: the highly optimized, memory-sensitive world of game clients and the backend infrastructure. You will bridge the gap between creative vision and technical reality, ensuring that the incredible experience enjoyed by players is powered by a robust, secure and scalable backend.

Main Responsibilities

What You Will Do:

• E2E Game Architecture: Design, implement, and maintain complete game features. You will seamlessly integrate scalable server-side backend services with high-performance client-side gameplay and UI logic
• Decoupled Systems: Design a flexible, modular backend that efficiently serves data to various frontend game clients, ensuring seamless integration regardless of the client engine used
• Full-Stack Optimization: Balance performance across the entire product. Optimize server-side load management and database queries while simultaneously managing client-side memory and frame rate stability across a wide range of devices
• Unified Observability: Implement robust real-time data collection, logging, and crash reporting, to track the user journey from client-side actions to back-end server responses
• System Health & Proactive QA: Monitor the entire stack to swiftly detect, diagnose, and resolve cross-domain issues – whether they originate as client-side crashes or backend server bottlenecks
• Security & Risk Mitigation: Implement E2E security protocols for secure client-server communication. Protect sensitive user data on the server while deploying client-side risk mitigation, such as anti-cheat mechanisms and exploit prevention
• Act as the Technical Translator: Serve as the core bridge connecting UI/UX designers, Game Designers, and engineering leadership. You will help translate creative requirements into actionable code while ensuring the backend can support those designs
• Elevate the Team: Mentor developers in modern client-side and backend techniques, fostering a culture of high-quality code and technical ownership
• Set the Standard for Documentation: Create and maintain a unified knowledge base covering both sides of the stack – from API specs and server infrastructure to engine integration manuals
• Drive Agile alignment: Holistically scope features during sprints, ensuring technical requirements align with business goals while actively managing and reducing technical debt

What to Expect:

• Strong Planning and prioritization: You will organize the plan so that you and the team can seamlessly shift gears from optimizing a memory allocation issue in the morning to designing a stateless architecture handling thousands of concurrent players in the afternoon
• Stakeholder management: You will work with product owners and game designers to translate their vision into technical reality, reviewing mechanics and proposing a viable, performant alternative
• Architecture engineering: You will marshal monitoring telemetry to ensure the servers stay up during massive traffic spikes and adjust the approach to facilitate high availability
• Product engineering: You will balance the demands of shipping features fast against the necessity of keeping the codebase clean, scalable, and modular
•  

Mandatory Requirements

• 6+ years of development experience and 1+ year of leadership experience
• iGaming/Gambling experience will be a huge plus
• Proven Full-Stack Expertise: Deep professional experience in both game client development and scalable server-side backend architectures
• High Tolerance for Complexity: You are comfortable diving into ambiguous problems and designing systems from the ground up
• Proactive Problem Solver: You find and fix memory leaks, architecture flaws, or security vulnerabilities before they ever impact a player
• Exceptional Communicator: You can explain complex backend constraints to non-technical stakeholders and break down creative requirements into clear engineering tasks
• Experienced Leader: You have a track record of mentoring engineers, driving architectural decisions, and leading projects through the full software development lifecycle

Nice to have:

• Experience with Python
•

N-iX is looking for Senior Kotlin Engineer - to join the team

Our client is a fast-growing European fintech company in the business spend management space. Products include smart corporate cards, software for business analytics optimisation, and automated invoice management. Operates primarily in Europe, serving SME and mid-sized business customers in a regulated environment (GDPR).  We're looking for a Senior Back-End Engineer to design, build and operate scalable Kotlin microservices on AWS, increasing delivery throughput without compromising quality

Responsibilities:

• Design, build and operate scalable Kotlin microservices on AWS.
• Apply AI-native delivery practices across the CDLC to increase delivery throughput without compromising quality.
• Work with distributed systems, relational databases (e.g. PostgreSQL), and observability tooling (e.g. Grafana) in production.
• Multiply the output and quality of the squad you join, and share patterns/practice beyond your immediate team so adoption compounds across the organisation.
• Embed directly into a client squad as a hands-on Individual Contributor (not a coaching/managerial role).

Requirements:

• 5+ years of commercial backend engineering
• Kotlin; scalable microservices on AWS.
• AI-native delivery practices applied across the CDLC
• Production experience with distributed systems
• Relational databases, e.g. PostgreSQL
• Observability tooling, e.g. Grafana
• Excellent English communication skills
• Experience working in Agile / Scrum / Kanban

Nice-to-Have:

• Specific AWS services (EKS, Lambda, SQS) or Prometheus. The RFP names AWS and Grafana only (Grafana as an example of observability tooling) — these additional specifics are common adjacent tools, not stated requirements

Senior Engineer (React/Node, GCP/Cloudflare), AI-native, long-term. Read the first lines before you apply.
 

IF YOU CAN'T SOLVE BASIC systemdesign.io PROBLEMS, DO NOT APPLY. I WILL THROW A SYSTEM DESIGN EXERCISE AT YOU DURING THE INTERVIEW, AND WE WILL BOTH LOSE TIME IF YOU CAN'T SOLVE IT.

This is not a formality. The URL shortener is the floor. If you can only solve the "easy" problems, this role is not for you. My last round of interviews was full of people who could not reason through a basic system, so I am being blunt on purpose.
 

WHO I AM
I am a senior developer and CTO running a small high-end dev agency. I only take serious, high-stakes work. No WordPress, no throwaway projects. Full remote, building for clients all over the world. This role is not customer-facing: you work directly with me, I deal with the clients. I want someone long-term who becomes part of the company and builds something real with me, done properly, never rushed or half-baked.
 

THE ROLE, DAY TO DAY
- Fully AI-driven. Your day is orchestrating AI agents (Claude, Codex, and similar), reading and reviewing their code, and holding the line on quality, including blocking a merge when the output is not good enough. You are not hand-writing everything.
- Building genuinely cool things and going deep on automation.
- Stack is mostly React and Node, plus GCP and Cloudflare.
 

WHAT I ACTUALLY NEED (this is the job)
- System design. You can take requirements and design a database schema, then defend your tradeoffs. You reason about concurrency: race conditions, locking, idempotency, what happens when two requests land at the same time. You can architect a system end to end: caching, cache invalidation, failure modes, blast radius, and what breaks when traffic goes 10x.
- Real infra and cloud: GCP, Cloudflare, CI/CD, deployments.
- You can sketch an architecture live in Excalidraw. It takes two minutes to learn. If you do not know it, learn it before we talk.
- You drive AI agents every day and review their output with a critical eye.
- Fluent English, reliable, autonomous.

SETUP
- Full remote, full time. Work whenever you want, as long as the work gets done.
- $2,500/month, plus I pay for your Claude Code Max plan.
- Your own machine for now. We can look at hardware later.
- Long-term, with room to grow and become part of the company.
 

HOW TO APPLY
No cover letter, I do not read them. Send a link to a short video, 3 to 5 minutes:
1. Camera on so I can see you, screen-share your setup, and show me how you drive and review your AI agents day to day.
2. Then pick one system-design problem (a URL shortener, or a read-heavy news site serving millions of reads a day) and walk me through your design while sketching it in Excalidraw: the database schema, how you handle concurrency, what you cache and how you invalidate it, and what breaks at scale.

Keep it real, not scripted. If you send a CV or a generic AI-written message with no system-design walkthrough, I will not reply.

IF YOU CAN'T SOLVE BASIC systemdesign.io PROBLEMS, DO NOT APPLY. I WILL THROW A SYSTEM DESIGN EXERCISE AT YOU DURING THE INTERVIEW, AND WE WILL BOTH LOSE TIME IF YOU CAN'T SOLVE IT.
