Responsibilities

• Customize and extend AOSP for specific product requirements
• Modify and debug Android system services (framework + native layers)
• Work with HALs, Binder IPC, and low-level system components
• Implement and adjust behavior related to:
  • Device identity & system properties
  • Networking, telephony, sensors, and system state
  • Power, battery, and lifecycle behavior
• Integrate and adapt Android builds for virtualized / emulated environments
• Debug complex issues across Java/Kotlin and native C++ layers
• Analyze system logs, traces, and crashes (logcat, tombstones, systrace, etc.)
• Collaborate with reverse engineers and backend teams on system behavior

Requirements

Core Skills

• Strong experience with AOSP (building, modifying, debugging)
• Solid knowledge of:
  • Android architecture (Framework, System Services, HAL)
  • Binder IPC and Android service model
• Proficiency in:

  • Java / Kotlin (framework layer)

System-Level Understanding

• Experience with:
  • SELinux policies and system permissions
  • Android boot process (init, Zygote, system_server)
  • System properties and device configuration
• Ability to debug across layers (kernel ↔ HAL ↔ framework)

Tools

• adb, fastboot, logcat, systrace
• Debugging tools (gdb/lldb, ndk-stack)
• Build system (Soong / Make)

Who This Is For

This role is for engineers who:

• Enjoy working below the app layer
• Are comfortable breaking and rebuilding Android internals
• Prefer solving real system problems over building UI

🔑  Ideal candidate:

• 7–10 years in iOS engineering / consulting, with senior-level ownership of complex mobile products

• 5+ years of hands-on Swift experience, including production work with SwiftUI

• Experience with SQLite, GraphQL and/or REST APIs, RxSwift, and Swift Package Manager in real delivery environments

Your Go experience caught my eye! We’re building a team for an international CPaaS platform that powers messaging for AliExpress and 500+ global brands. And looking for a Full Stack Engineer (Go + React). 15+ years on market, flexible remote setup, strong team.

We are looking for a Senior Full Stack Engineer who is comfortable working on high-load, distributed systems and making architectural decisions, not just implementing tasks.

You will work on a CPaaS/CCaaS platform handling messaging and voice communication at scale. This is not a typical CRUD product: you’ll deal with real-time flows, external integrations, billing complexity, and systems where design mistakes surface quickly in production. You will be expected to take ownership from design to delivery and challenge assumptions when needed.

Main Responsibilities

– Design and implement new platform capabilities across backend and frontend (not just “features” but system-level improvements)

– Contribute to architecture decisions in a microservices environment (Go-based services, event-driven patterns, APIs)

– Build and evolve React-based interfaces used by enterprise customers and internal teams

– Work on integrations with external vendors (messaging providers, voice, billing systems)

– Investigate production issues in a high-scale environment and drive them to resolution—not just patch them

– Participate in technical discussions, trade-off analysis, and system design reviews

– Occasionally lead initiatives or own a domain end-to-end

Mandatory Requirements

– 4+ years of real production experience as a Full Stack Engineer

– Strong backend expertise with Go (3+ years), not just syntax, but concurrency, performance, and system design

– Solid frontend experience with React + TypeScript (2+ years)

– Experience building or maintaining distributed systems / microservices

– Good understanding of data modeling (SQL + NoSQL) and when to use each

– Ability to debug complex issues across services (not limited to your own code)

– Comfortable working in an environment where requirements evolve and not everything is predefined

Will be a plus

– Experience with real-time systems, messaging, or telecom domains

– Familiarity with event streaming (Kafka or similar)

– Experience with cloud platforms (GCP preferred)

– Exposure to billing systems or high-throughput APIs

What you get

– Work on systems that actually operate at scale and have real business impact

– A team where senior engineers are expected to influence architecture, not just execute

Remote work

We offer

– Your Wellness: Access to mental health programs, comprehensive medical insurance, and a sports card

– Your Happiness: Enjoy the company of cool teammates, a friendly atmosphere, a strong mentorship, and a variety of bonuses & corporate gifts

– Your Development: Benefit from free educational events & courses, and English classes with native speakers

– Your Career: Focus on your professional development in a supportive environment

– Work-Life Balance: Choose your working format – remote, office-based, or hybrid and engage in team-building activities

Think this role’s got your name on it? Go ahead and apply, we’d love to see what you’ve got!

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.
