About the Client

Our client is a leading enterprise data platform company building an open, high-performance data lakehouse for AI and analytical workloads. The platform combines an intelligent SQL query engine, an AI-ready semantic layer, and an open catalog built on Apache Iceberg — enabling Fortune 500 companies across finance, energy, manufacturing, and logistics to unify, query, and govern data at massive scale across cloud and on-premise sources.

About the Role

We are looking for a Senior SDET to lead the design of automated test frameworks and testing strategy for a large-scale distributed data platform. You will own the quality of the query engine, connectivity layer, and backend services end-to-end — from framework architecture through CI/CD infrastructure across all major clouds — and mentor middle engineers on the team.

This is a data-heavy, backend-focused role. We are not looking for web/UI QA engineers — the work centers on validating distributed query execution, data correctness at scale, connectivity drivers, and backend microservices.

Responsibilities

• Architect, design, and evolve automated test frameworks in Python / pytest for backend services, REST APIs, and distributed data components.
• Define testing strategy for new features and platform components — coverage, risk assessment, and quality gates.
• Own end-to-end, integration, performance, and regression testing covering SQL query execution, data correctness at scale, and platform APIs.
• Lead performance and load testing efforts with JMeter, including workloads over JDBC / ODBC / Arrow Flight drivers.
• Design and validate large-scale data testing scenarios — query plans, result correctness across heterogeneous data sources, metadata consistency, and behavior under high concurrency.
• Own CI/CD test pipelines in Jenkins — architect, maintain, and continuously improve.
• Provision and manage test environments in Kubernetes (GKE / EKS / AKS) across GCP, AWS, and Azure using Docker; drive automation and reproducibility.
• Investigate complex, cross-layer failures and drive root-cause analysis with engineering.
• Mentor middle SDETs, review test designs, and set quality standards across the team.
• Partner with US-based development leads on shift-left practices, testability, and release readiness.
•  

Required Qualifications

• Education: B.S. or M.S. in Computer Science, Computer Engineering, or a related technical field.
• Programming: Strong proficiency in Python, including pytest, with deep understanding of OOP, software design principles, and test framework architecture.
• SQL & Data: Advanced SQL skills and strong understanding of relational and analytical data systems, including query execution internals.
• Data-intensive testing experience: Demonstrated experience testing data-intensive systems — query engines, ETL/ELT pipelines, streaming platforms, or analytical databases. Candidates with only web/UI QA backgrounds are not a fit.
• Testing experience: 5+ years in backend/system test automation, with demonstrated ownership of test strategy and infrastructure.
• CI/CD & DevOps: Solid experience architecting and maintaining Jenkins pipelines and test environments.
• Containers & Orchestration: Strong working knowledge of Docker and Kubernetes (running workloads, debugging pods, deploying complex environments).
• Cloud: Hands-on experience with at least one major cloud (GCP, AWS, or Azure); exposure to more than one is a strong plus.
• Version Control: Confident with Git / GitHub workflows and code review practices.
• English: Upper-Intermediate or higher (B2+) — daily written and verbal communication with a US-based engineering team.
• Availability: Able to work EU hours with a 2–3 hour shift toward US West Coast time to ensure daily overlap with the client team.
• Leadership: Prior experience mentoring engineers, defining test strategy, or leading a QA/SDET function.
•  

Desired Skills

• Deep experience testing REST APIs and backend microservices at scale.
• Hands-on with distributed computing frameworks (e.g., Apache Spark, Kafka) and MPP SQL query engines (e.g., Presto, Trino, or similar).
• Strong understanding of modern data lakehouse concepts, open table formats (Apache Iceberg), and data warehousing.
• Experience with data connectivity drivers: JDBC, ODBC, Arrow Flight.
• Performance testing with JMeter or comparable load-testing tools at production scale.
• Kubernetes on managed services (GKE / EKS / AKS) and multi-cloud exposure.
• IaC tools such as Terraform.
• Deep understanding of query plan generation, query acceleration / materializations, and metadata integrity in distributed data systems.
• Prior experience leading a QA/SDET function in a data-platform or database engineering environment.

At Whitechain, we’re on a mission to revolutionize blockchain, smart contracts, and cryptography. As part of the WhiteBIT ecosystem, we’re building cutting-edge Web3 solutions, from our own EVM blockchain to non-custodial wallets, DeFi platforms, and GameFi experiences.We’re looking for ambitious innovators to help us bridge the gap between retail and corporate blockchain adoption. If you’re passionate about decentralization, Web3, and shaping the future of digital economies, this is your chance to make an impact!

The future of Web3 starts with you — join us as a Front-End Engineer!
 

Requirements:

— 4+ years of professional front-end experience, with production experience predating AI-assisted development – we require an engineering foundation built before coding agents, verified at interview through deep debugging and fundamentals questions;
— Strong React + TypeScript; production experience with Next.js (App Router, server components);
— Practical web3 experience: worked with wallet integrations (custodial or non-custodial), querying RPC nodes, and reading on-chain data, with a working grasp of blockchain fundamentals – transactions, gas, nonces, and EVM basics;
— Hands-on production experience with viem and wagmi (current major versions): wallet connection, contract reads/writes, transaction lifecycle handling (pending/confirmed/stuck/replaced);
— Experience building or integrating cross-chain bridge flows (deposit/withdrawal UX, multi-chain state, confirmation tracking);
— Experience working in a monorepo with shared packages: consuming and contributing to a shared component/utility library, semantic versioning, changelogs, avoiding breaking downstream apps;
— Strong practical AI-tooling expertise: running coding agents (e.g. Claude Code or similar) including parallel agent workflows, reviewing and correcting AI-generated code, building agentic pipelines; a forward-looking mindset toward AI-assisted engineering is a hard requirement;
— Ability to review someone else’s code critically – including AI output – and catch subtle correctness issues, especially in transaction/signing paths;

Would be a plus:

— React Native experience;
— OP-stack rollup experience or knowledge (sequencer, L1 data posting, deposits/withdrawals);
— DeFi protocol familiarity (AMMs/DEXes, token approvals, allowance UX);

— Accessibility and i18n experience;
 
 

Responsibilities:

— Maintain and extend the shared front-end packages (UI components, utilities, web3 helpers, configuration) consumed by all Whitechain applications: triage, fixes, releases, and non-breaking evolution;
— Stand up new user-facing applications quickly from the internal boilerplate and shared platform, taking them from scaffold to production;
— Build and maintain blockchain-facing features day-to-day: wallet connection, contract interaction, transaction submission and confirmation tracking, chain switching, error and edge-case handling;
— Implement and maintain cross-chain bridge user flows (deposits, withdrawals, status tracking);
— Work AI-first: execute with coding agents, run parallel agent workflows where appropriate, and apply rigorous human review to everything an agent produces – with extra scrutiny on signing/transaction code;
— Act as second reviewer on web3-sensitive code paths;
— Contribute to e2e/visual-regression test coverage and keep CI quality gates green;
— Follow and contribute to engineering conventions, ADRs, and documentation.

Work conditions:

Immerse yourself in Crypto & Web3:

— Shape the Future — Work on high-impact blockchain products at the forefront of Web3.
— Innovate & Create — Your ideas drive real-world solutions and technological breakthroughs.
— Global Reach — Build scalable solutions for businesses and users worldwide.
