So if you're someone who thinks big, moves fast and wants to make an impact right from day one, then get ready to join our industry-changing team.
The Role
As Tech Lead, iOS, you’ll be the primary technical owner of the 1inch Wallet iOS application. This is a hands-on individual contributor role with no direct people management responsibilities.

Build and improve modular, testable application components, and guide implementation across complex wallet flows.
Implement wallet features and technical improvements across the iOS application.
Integrate the application with backend services, blockchain networks and related wallet services.
Work with Product, Android, Backend, Blockchain and QA on shared product behaviour, API integrations, test coverage and defect investigation
Use AI-assisted tools in development and testing, reviewing and validating their output against engineering, quality and security standards.
Protect sensitive information by keeping private keys, recovery phrases, credentials and user data out of AI prompts and inappropriate logs.
Own and improve the iOS build and CI/CD workflow; monitor releases, investigate production issues and coordinate fixes and improvements to stability.
Who you are
You have strong hands-on iOS development experience with Swift, including experience building production applications.
You have practical experience working on a Web3 product, such as a wallet, DeFi application or product integrating with blockchain networks, and an understanding of crypto and trading.
You have experience with iOS build and CI/CD workflows and monitoring production applications.

You communicate technical trade-offs clearly and work well with Product, Android and QA.
You are comfortable taking ownership of the iOS application while working independently as its primary iOS technical owner.
You are pragmatic: you can move quickly while keeping reliability, security and maintainability in mind.
You use AI tools thoughtfully, question their output and take responsibility for the code you deliver.
Nice to haves
Experience building or maintaining a non-custodial wallet.
Experience with transaction signing, wallet recovery or transaction lifecycle flows.
Experience building modular, testable applications and handling asynchronous operations and network failures.
Experience with security-sensitive mobile functionality, mobile security reviews or incident response.

We are looking for an experienced Fullstack QA Engineer with a background in fintech, banking or other finance-related products to join our banking QA team. We build mobile banking apps on shared backend APIs. You will test both mobile apps and backend services by hand and help us build test automation for APIs and mobile apps. Our products move real money - cards, transfers, payments - so quality here matters.
What You Will Do
Test new features and run regression for iOS and Android apps;
Test backend APIs and integrations: requests, responses, logs;
Design and maintain test cases and checklists in TestRail;
Build, maintain and run automated API tests with Postman and Newman in GitLab CI;
Maintain and extend our existing Java / REST Assured API test framework (TestRail integration, Allure reporting), and bring it back to regular runs;
Contribute to mobile UI test automation for iOS and Android — together with developers in their native test suites or with cross-platform tools — with a focus on end-to-end checks against the real backend;
Prepare test data and test accounts for automated and manual runs;
Help evolve our test automation approach and tooling;
Clarify requirements directly with developers and product managers — we have no business analysts, so you will often find out how things should work yourself;
Take part in release checks (release candidate testing, post-release smoke) and help improve QA processes;
Use AI tools to speed up your work — and verify what they produce.
Requirements
3+ years of experience as a QA Engineer;
Experience in fintech, banking, payments or other finance-related products;
Solid test design skills: you write test cases and checklists from short task descriptions;

Hands-on API test automation: comfortable reading and extending automated API tests in code (Java or Kotlin preferred) and writing simple tests by analogy - not framework architecture from scratch - plus Postman/Newman (scripts, environments, collections); experience running it in CI;
Proxy tools - Charles or Proxyman: inspecting traffic, breakpoints, mocking responses;
Working with logs to localise bugs;
Strong communication skills and a proactive attitude: you ask questions, dig into unclear tasks and own the result;
Readiness to test manually - this is not a pure automation role;
Russian - native․
Nice to have
Building test automation in code from scratch: framework, CI pipeline, reporting;
GitLab CI: pipelines, schedules, artifacts;
Basic SQL;
Mobile UI test automation: Appium, Espresso/Kaspresso or XCUITest;
Experience with feature flags and testing releases with partial rollout.
Benefits
Fully remote work;

About the job
We have launched Keet Mobile on iOS and Android, bringing our full P2P technology stack to everyone. Keet Mobile is not your average app: it’s heavy lifting is performed by a custom JS runtime specially designed for peer-to-peer usage (in fact, it reuses 100% of Keet Desktop’s code!). The UI logic, on the other hand, is 100% React Native, giving us flexibility and the ability to iterate quickly.
We believe this pattern opens the door to huge possibilities in the future, and we need your help getting there!
Responsibilities
In this role, you will develop and maintain Keet Mobile, our peer-to-peer chat and calling app for iOS and Android. Keet Mobile is built with React Native and Expo, and its P2P core runs on the device itself in a Bare worklet. You'll own features end to end, from UI/UX implementation to using the P2P core apis.
You will:
- Build and polish features across chat, voice and video calls, media sharing, device pairing and identity backup
- Integrate native platform capabilities such as push notifications, camera, bio-metrics and background tasks on both iOS and Android
- Profile and optimise performance on real devices, including startup time, long chats, media handling, battery and network use
- Write unit and end-to-end tests, and help keep releases stable through CI and crash reporting
- Work closely with the core P2P, design and product teams, and review code with a high bar for quality
