• Review business requirements, mobile designs, and technical specifications during Agile ceremonies to identify potential issues early and establish clear acceptance criteria.
• Manual & Exploratory Diagnostics
• Execute manual functional, regression, and exploratory testing on physical devices and emulators/simulators to discover edge cases and usability issues.
• Reproduce, isolate, and log detailed bugs, providing developers with precise steps to reproduce, screenshots, videos, and native system/network logs.
• Validate native device interactions, gestures (swiping, pinching, tapping), and application behaviors under variable network profiles and system interrupts.
• Mobile Automation Framework Engineering
• Build, configure, and expand our mobile test automation framework from the ground up to support both iOS and Android applications.
• Architect a clean, modular page-object framework that enhances our current test coverage and supports automated regression runs.
• Integrate mobile automated suites into our existing continuous delivery (CI/CD) pipelines and debug failed deployments.

Arise is a globally active weight-loss app with over 10 million downloads and a 4.7 rating on the App Store. Our mission is simple but ambitious: empower millions of people to become healthier and happier.

We're bringing Arise to Android — and we're looking for the developer who will build it. You'll be creating the Android version from the ground up, making the architectural decisions that will define the app for years to come. You'll work alongside our iOS developer and CEO (who built the original app) to deliver a product that matches the quality our millions of users expect.

If you thrive on ownership, make strong technical decisions independently, and want to build something used by millions, we'd love to hear from you.

Your Role:

• Build the Arise Android app from scratch — architecture, implementation, and release.
• Own the Android codebase end-to-end from day one.
• Make architectural decisions that balance speed of delivery with long-term maintainability.
• Collaborate with design to refine usability for a smooth user experience.
• Align with the iOS developer to ensure cross-platform consistency.
• Support monetization strategies by integrating features with measurable business impact.

Requirements:

• Middle 2+ Level Developer with proven track record.
• Minimum 4 years of Android development experience.
• Experience building an app from scratch — not just contributing to an existing codebase.
• Bachelor's degree in IT or related field preferred.
• Excellent problem-solving and critical-thinking skills.
• Comfortable working fully in English.
• Technical Skills
• Strong knowledge of Kotlin.
• Experience with Gradle and CI/CD tooling.
• Solid understanding of Material Design principles, patterns, and best practices.
• Ability to write clean, well-documented, and maintainable code.
• Why You'll Love Working with Us
• High autonomy: own your work from idea to release.
• Clear decision-making with minimal bureaucracy — no "meetings that should have been emails."
• Work with the newest hardware and technologies.
• Complimentary Claude Max subscription.
• Flexible, remote-first role (full-time).
• Paid annual leave.
• Direct collaboration with founders and management — your work will have visible impact.

Technical Product Manager – Mobile

At Öneriver, we build technology products for financial institutions and help our clients create better digital experiences.

We are looking for a
Technical Product Manager with 3–5 years of experience
to join our mobile product team.

This is not a traditional Product Manager role. We are looking for someone with a strong engineering background who can understand both the
product and technical sides of a problem
, work closely with engineering teams and engage directly with clients when needed.

The role will also include some aspects of the
Forward Deployed Engineer
approach: understanding real client problems, going deeper into technical details and helping teams turn those problems into practical solutions.

What You Will Do

• Own the technical product management of our mobile products.
• Understand business and client needs and turn them into clear technical requirements.
• Work closely with mobile, backend, frontend, DevOps, QA and other engineering teams.
• Contribute to the design of APIs, integrations, authentication flows and system-to-system data flows.
• Understand how mobile applications interact with backend services and third-party systems.
• Investigate technical issues by reviewing API requests/responses, logs, error messages and system behavior.
• Work directly with clients and their technical teams when needed.
• Understand client-specific problems and identify solutions that can become part of the core product.
• Create clear user stories, acceptance criteria, API flows, sequence diagrams and other technical documentation.
• Manage priorities between product roadmap, client needs, technical improvements and technical debt.
• Follow features from analysis and development through testing and production.
• Follow new technologies and use AI-assisted development and product tools where they can improve the way we work.

What We Are Looking For

• Bachelor's degree in Computer Engineering, Software Engineering, Computer Science or a related technical field.
• 3–5 years of experience
  in software development, technical product management, solution engineering or a similar role.
• Good understanding of the software development lifecycle.
• Good understanding of REST APIs, JSON, HTTP, authentication, authorization and system integrations.
• Basic knowledge of mobile application architecture and mobile-backend communication.
• Ability to work with SQL and relational databases for basic analysis and troubleshooting.
• Experience with tools such as Postman and Swagger/OpenAPI.
• Ability to read logs and investigate technical problems.
• Ability to create and understand sequence diagrams and system flows.
• Strong analytical and problem-solving skills.
• Ability to communicate effectively with both engineering teams and business stakeholders.
• Good command of English.

Nice to Have

• Previous hands-on software development experience.
• Experience with iOS or Android development.
• Knowledge of Java, Kotlin, Swift, JavaScript/TypeScript or a similar programming language.
• Understanding of microservice architectures.
• Familiarity with OAuth2, OpenID Connect and JWT.
• Familiarity with technologies such as Kafka, SSE or WebSocket.
• Basic knowledge of CI/CD, containers and cloud-native development.
• Experience in fintech, banking, investment or capital markets.
• Experience with B2B or enterprise products and client integrations.
• Experience investigating production issues.
• Experience using AI coding tools and LLM-based development tools.

Who Will Be Successful in This Role?

We are looking for someone who does more than forward a technical problem to the engineering team.

When a client says,
"This feature is not working in the mobile app,"
we expect you to start asking questions such as:

Which API is being called? What does the request look like? What is the response? Is the issue related to authentication, backend services, integration or the mobile application?

You don't need to be the person who writes every line of code. But you should be comfortable going into technical details, asking the right questions and working with engineers to find the right solution.

In short, we are looking for someone who combines the
product mindset of a Product Manager with the technical curiosity of an Engineer.
