N-iX is a global software development company founded in 2002, connecting over 2,400+ tech professionals across 40+ countries. We deliver innovative technology solutions in cloud computing, data analytics, AI, embedded software, IoT, and more to global industry leaders and Fortune 500 companies. Join us to create technology that drives real change for businesses and people across the world.

Our client - Europe's largest online car marketplace with 30M+ monthly users across 18 countries - is investing in a next-generation Agentic Software Delivery platform. The goal is to enable autonomous engineering at scale, starting with SDLC automation and expanding further: humans steer, agents deliver.
This is a greenfield environment. A dedicated team will build an end-to-end platform on AWS, integrating with internal systems and delivery processes. The target is for 10–20% of JIRA stories to be handled through fully autonomous delivery within 12 months.

We are looking for a self-driven Engineer with AI experience who thrives in ambiguity and takes ownership without waiting to be directed. This is a proactive role - you are expected to identify problems, propose solutions, and drive them independently.
In addition to engineering, ~10% of your time will involve working with internal delivery teams: understanding their SDLC processes, identifying friction points, and feeding insights back into the platform. You will also support adoption by explaining and promoting the solution across teams.

Must-Have Requirements:

• 5-7+ years of full-stack software engineering experience.
• Hands-on experience with agentic coding tools (e.g. Claude Code, GitHub Copilot, Codex, Cursor) and an understanding of how they work underneath: model APIs, tool calling, agent loops, context management.
• Understanding of LLM API and tool-use patterns: function calling, tool orchestration, and the ability to integrate AI models programmatically, not just through existing UIs.
• Ability to evaluate trade-offs between off-the-shelf agentic tools and custom API-based implementations.
• Genuine enthusiasm for and an informed opinion on where agentic tooling is heading.
• Strong full-stack fundamentals; comfortable owning significant pieces end-to-end across frontend and backend.
• Solid experience in any primary backend language (Java, Python, etc.) combined with React or any other modern frontend framework.
• Proactive, self-driven mindset, able to work independently without detailed instructions.
• Strong communication skills in English (B2–C1).
• Comfortable working in greenfield environments with evolving requirements.

Strong Plus:

• Workflow Engines: Experience with workflow or orchestration engines (e.g. Camunda, N8N, or similar).
• Camunda experience specifically is a significant advantage given the current architectural direction.
• Familiarity with AWS AI services; AWS AI Practitioner certification (AIF-C01) is a notable bonus.
• Exposure to cloud-native orchestration patterns and multi-agent system design.

Mindset & Soft Skills:

• Proactive and self directed, drives outcomes without waiting for direction.
• Comfortable with ambiguity, makes pragmatic decisions when the path is not fully defined.
• Strong technical communication, effectively collaborates with peer engineers to understand domain context.
• Forward thinking, stays current with the AI and agentic tooling landscape and brings new ideas.
• Energized by transforming software delivery, not just a participant but a believer.

Who we are and who we’re looking for:

Cleo is not a place for developers who want to hide behind tickets and meetings.

We've built and are now evolving a next-generation trading platform, engineered for thousands of concurrent traders, delivering transparency and features unmatched in the industry, challenging and slowly beating giant corporations 100x our size.
 

Our success is rooted in a developer-first environment, free from middle management and corporate red tape - just pure focus on building. Extraordinary teams are built by extraordinary people - if you’ve ever felt unable to reach your full potential, felt a lack of impact, or weren’t challenged enough in your previous jobs, Cleo is the place to change that. If you ever wondered how your favorite tech influencer built his skillset and knowledge - join our team and experience the journey yourself, but don’t expect it to be easy.

This is an AI-native engineering role: you’ll be expected to use AI tools heavily for coding, testing, research, refactoring, and workflow automation - while still owning the correctness of the output.

Ideal candidate must:

• Genuinely enjoy software development

• Understand system design and design patterns beyond textbook definitions

• Can debug hard problems without waiting for perfect instructions

• Can explain technical tradeoffs clearly even to non-technical people

• Keep up with new tools, frameworks, and AI workflows

• Be proactive and take ownership instead of waiting to be assigned every task

What can you expect?

• Taking ownership of important parts of the project

• Working remotely with flexible working hours

• No corporate management or unnecessary meetings, just pure software development

• You will not just be following tasks; you will be assessing what needs to be done by yourself

• Working with the latest modern frameworks, services, and AI tools

• An amazing team of smart people where your ideas will be heard

What will you actually do?

• Categorical examples of tasks you might get:

○ Designing & implementing distributed cache for microservices

○ Implementing resilient trading data WebSocket streams

○ Optimizing order matching systems

○ Refactoring public APIs and docs

○ Researching new AI tools for suitability in our workflows

○ Setting up automated parallel AI testing pipelines

• Exploring new frameworks, services, and AI tools, then deciding what is actually useful

• Using AI heavily, but not blindly - verifying outputs, building guardrails, and improving workflows

• Architecture and system design of small components up to big services

Our tech stack:

• .NET C#, React - TypeScript

• MongoDB, PostgreSQL, EF

• Microservices, RabbitMQ, SignalR, ELK stack

Our hiring process:

1. Screening: 15-40 min MS Teams call with our Dev Team Lead

2. Task: Take-home coding task (you can use AI)

3. Follow-up: Call with 1-2 devs about your task solution + follow-up questions

4. Final evaluation: Call with our CEO to discuss the role and expectations in detail

Remuneration depends on skill level, ownership, and the value you can create. For this role, we expect most candidates to land around 2k-3k $/month, with room to go higher for someone who can take serious ownership from day one. Across the company, our technical compensation range is roughly 1.5k-5k $/month, from junior to senior-level contributors. We don’t care much about years of experience on a resume; we care about what you can actually deliver. We know that a hardworking developer with one strong year can outperform someone with 10 years in the industry, which we reward accordingly.

We move quickly, but we also filter quickly. If you bluff, exaggerate your experience, ignore the job post, or try to cheat your way through the process, it will become obvious fast and will only waste your time and ours.

We’re launching a new subscription mobile app for the US market, and we’re looking for a Senior User Acquisition Manager to own paid growth from day one. This is a strategic, high-ownership role across Meta, TikTok, Apple Search Ads, and ad networks, with room to layer in additional channels as we scale, but the primary responsibility is to work with Meta.

This is not a campaign-launch executor role. We need someone who has scaled a subscription app profitably in the US market before, thinks in LTV-payback horizons rather than day-1 ROAS, and can build a paid acquisition function from the ground up.

What you’ll own

• Full ownership of paid user acquisition on Meta Ads: strategy, structure, budget, optimization.
• Building the paid acquisition function: account architecture, naming conventions, measurement setup, testing cadence.
• Profitable scaling against subscription unit economics: CAC, LTV, payback period, trial-to-paid, ROAS D7/D30/D90, not just spending the budget.
• Measurement and attribution.
• Works closely with product, analytics, and design teams.

• Reporting that connects ad metrics to business metrics: CAC, LTV, payback, blended efficiency, and translating them into clear decisions for leadership.

   

Requirements

• 3+ years in paid user acquisition for mobile apps, with experience on subscription models
• Hands-on experience scaling subscription apps profitably in the US market: you can walk through a real app you grew, the unit economics, and the decisions behind them
• Deep, hands-on expertise in Meta App Campaigns (Advantage+ App Campaigns, AEO, Value Optimization)
• Multi-platform experience: iOS, Android, and web-to-app flows
• Fluency in subscription metrics: CAC, LTV, CAC: LTV ratio, payback period, ROAS D7/D30/D90, trial-to-paid conversion and how they trade off
• Strong working knowledge of SKAdNetwork (conversion value schemas, postback handling) and at least one MMP (AppsFlyer, Adjust, or Branch)
• Advanced analytical skills: you build your own dashboards and pull your own insights

• Upper-Intermediate (B2+) English

   

Nice-to-have

• Background in pet training, education, or lifestyle subscription apps
• Hands-on Apple Search Ads experience
• Experience launching a paid acquisition function from zero (0→1 product stage)
• Working knowledge of ASO and how it interacts with paid traffic
• Experience managing relationships with ad networks and negotiating placements/rates

• Comfort with automation tools (rules, scripts, Zapier) to remove manual work

   

Benefits

• Great compensation package with company-wide benefits
• Silicon Valley-rooted startup environment with a sharp focus on the US market
• Rapid professional development in a healthy corporate culture
• 24 days of paid vacation
• Remote work
• Health benefits
