Ukraine&Abroad | Full-Time | Full-stack | Remote 

About the role

We're growing two teams and looking for skilled Software Engineers with a product mindset to join either:

• Plug&Play (AI team) — owns Git integrations, remote content, AI infrastructure, and webhooks. We're looking for someone with at least some experience or solid conceptual understanding of how modern AI/LLMs work (prompting, embeddings, RAG, agent/tool-use patterns, or similar) — you don't need to be an ML engineer, but you should be comfortable reasoning about and building around LLM-based features.
• Borshch (DevOps team) — our infrastructure team, skewed toward backend, cloud infrastructure, deployment, and DevOps. We're looking for someone hands-on with AWS and Terraform, who's comfortable moving between backend development and infrastructure/DevOps responsibilities.

Both teams work on real product features end-to-end — architecture, implementation, testing, and monitoring — with strong ownership over their area.

What you'll do

• Design the architecture for your team's area (AI infrastructure & integrations for Plug&Play; cloud infrastructure & deployment for Borshch)
• Lead full-stack feature development — from API design to UI/backend implementation
• Write reusable code and internal libraries
• Optimize applications for speed, scalability, and reliability
• Solve bugs across the stack
• Cover functionality with tests and monitoring
• Work closely with product, design, and engineering peers
• Contribute across all phases of the development lifecycle
• Bring fresh ideas and suggest new technologies relevant to your team

Who you are

• 4+ years of experience as a full-stack or backend engineer (Mid+ for Plug&Play, Senior for Borshch)
• Strong proficiency with Node.js, JavaScript, TypeScript
• Experience with NestJS
• Experience with Postgres
• Comfortable owning a feature or system end-to-end, including architectural decisions
• Strong communication — you share your thinking and ask questions proactively
• A team player who puts the mission ahead of individual preference
• Beauty and simplicity of your code
• Upper-Intermediate or higher English

Important, depending on the team:

• For Plug&Play: some experience or working knowledge of modern AI/LLMs
• For Borshch: hands-on experience with AWS and Terraform (or similar infrastructure-as-code tools), and a DevOps mindset — happy to own deployment pipelines, CI/CD, and system reliability

Nice to have

• GraphQL
• Cloud experience (AWS) — required for Borshch, a plus for Plug&Play
• Infrastructure as code (Terraform, HashiCorp)
• Experience with vector databases or LLM orchestration frameworks (LangChain, LlamaIndex, etc.)
• Experience with containerization (Docker) and orchestration (Kubernetes/ECS)
• Familiarity with observability tooling (Datadog, Grafana, Prometheus, etc.)

• Manage releases through Google Play, Firebase App Distribution, and alternative distribution channels;
• Support different product flavors, regional builds, and white-label configurations;
• Update dependencies, improve legacy code, reduce technical debt, and introduce unit tests;
• Participate in code reviews and collaborate with development and QA teams.

Required experience and skills

• 5+ years of commercial native Android development experience;
• Strong Senior-level ownership and the ability to work independently with a large production codebase;
• Expert knowledge of Kotlin;
• Ability to read, understand, and modify production Java code;
• Strong hands-on commercial experience with RxJava, preferably RxJava 3, including RxAndroid;
• Strong practical knowledge of the classic Android View system: XML layouts, ViewBinding, and custom views;
• Practical commercial Android BLE experience;
• Experience with GATT services and characteristics, including read/write/notify operations;
• Experience with BLE connection management, reconnect logic, background restrictions, foreground services, and connection stability;
• Experience with Hilt or Dagger 2;
• Experience with Room and Android Navigation Component;
• Experience maintaining large multi-module Gradle projects;
• Understanding of build variants, product flavors, and complex build configurations;
• Experience with the Google Play release lifecycle;
• Experience maintaining and debugging production applications;
• Ability to investigate issues and make technical decisions without constant supervision;
• English level B2 or higher.

As a plus

• RxAndroidBle or similar BLE libraries;
• OTA/DFU experience, including Realtek/RealSil or similar solutions;
• WebRTC, audio/video calls, and audio-routing experience;
• Wear OS and Jetpack Compose experience;
• End-to-end encryption, Olm/Matrix, or SQLCipher;
• Media3, ExoPlayer, or MediaSession;
• GitLab CI and fastlane;
• Firebase App Distribution;

What we offer

• Fully remote, full-time cooperation;
• A long-term product with an established user base;
• Work with technically complex mobile functionality and physical Bluetooth devices;
• A professional development plan and regular feedback;
• Compensation for approved courses and certifications;
• 20 paid working days per year for vacation and sick leave;
