Full Stack Developer (MVP / AI / Telegram Mini Apps)

Andersen is hiring a Product/Software Engineer (Node.js+React) for a project developing a SaaS testing platform and enhancing its scalable Public API capabilities.

The customer is a technology-driven software quality services provider that helps organizations improve the reliability, usability, and performance of their digital products. It combines quality engineering expertise, flexible delivery models, and technology-enabled services to support web, mobile, and other digital solutions across multiple industries. The company helps businesses accelerate software delivery, improve product quality, and enhance end-user experience through scalable testing and quality assurance services.

The project is focused on developing and enhancing a software testing SaaS platform that connects businesses with a global network of professional testers. It enables web and mobile application testing, issue tracking, tester management, and secure access to testing data through a Public API.

• Developing and evolving Node.js/TypeScript microservices (~40–50 services) on a mature SaaS platform for software testing.
• Owning features end to end: clarifying the business problem with stakeholders, proposing the most effective solution, writing the test plan before implementation, delivering to production and verifying the result.
• Building event-driven flows on Kafka: fan-out to multiple consumers, idempotent processing, ordering guarantees, failure handling (retries, DLQ, replay), transactional outbox.
• Designing cross-service data aggregation: GraphQL over REST microservices, BFF-style composition, cross-service sorting, filtering and pagination.
• Developing frontend features in React + TypeScript (GraphQL/Apollo).
• Testing own work (no dedicated QA; staging, regression suites, feature-flag rollouts) and reviewing teammates' PRs against requirements and functional correctness.
• Using Claude Code daily in design, planning, implementation and code review, with full ownership of the result.

• Backend development with Node.js and TypeScript, including production microservice architectures, for 6+ years.
• Experience with AWS (ECS, SQS, S3).
• Real production experience with Kafka, RabbitmQ and event-driven systems: delivery guarantees, idempotency, event ordering, failure handling and data consistency.
• Hands-on experience with concurrency control, including optimistic locking and conflict handling.
• Deep knowledge of distributed-systems patterns and hands-on experience applying them appropriately: transactional outbox, BFF/aggregation layer, DLQ.
• Familiarity with saga and CQRS.
• Strong code-review skills: verifying work against requirements and spotting functional, security and performance issues.
• Production experience with React and TypeScript: building user-facing features end to end, component architecture, state management, data fetching with GraphQL/Apollo, and frontend testing.
• Experience using GraphQL as an aggregation and composition layer across backend services.
• Experience using Claude Code in daily development workflows, including skills, hooks, MCP, and shared team conventions, with thorough testing and review of AI-generated changes.
• Level of English – from Upper-Intermediate and above.

• Experience in product companies or small teams without QA, owning features from idea to metrics.
• Experience with feature flags and phased rollouts (LaunchDarkly or similar).
• Experience with JWT-based authorization models and S3 pre-signed URLs.
• Experience migrating microservices to a modular monolith.
• Experience with Koa.
• Ability to read PHP (legacy monolith, <5% of work).

• Experience in teamwork with leaders in FinTech, Healthcare, Retail, Telecom, and others. Andersen cooperates with such businesses as Samsung, Siemens, Johnson & Johnson, BNP Paribas, Ryanair, Mercedes, TUI, Verivox, Allianz, T-Systems, etc..
• The opportunity to change the project and/or develop expertise in an interesting business domain.
• Job conditions – you can work both fully remotely and from the office or can choose a hybrid variant.
• Guarantee of professional, financial, and career growth! The company has introduced systems of mentoring and adaptation for each new employee.
• The opportunity to earn up to an additional 1,000 EUR per month, depending on the level of expertise, which will be included in the annual bonus, by participating in the company's activities.
• Access to the corporate training portal, where the entire knowledge base of the company is collected and which is constantly updated.
• Bright corporate life (parties / pizza days / PlayStation / fruits / coffee / snacks / movies).
• Certification compensation (AWS, PMP, etc).

THE ROLE

We are looking for an Engineering Team Lead to drive the technical vision, delivery, and culture of our B2B Integrations team at Farfetch. In this critical role, you will lead a multidisciplinary team of backend and integration engineers responsible for the nervous system of our B2B ecosystem. Your team will own the core pipelines that power our platform: ingesting complex global product catalogs at scale, and ensuring the seamless, real-time routing of outbound orders and returns with our B2B partners.

You will join a dynamic, inclusive, and highly collaborative environment where engineering excellence is paramount. If you are passionate about building fault-tolerant distributed systems, scaling high-performing teams, and shaping the architecture that connects Farfetch with its global partners, this is the opportunity for you.

What You'll Do
Lead & Empower: Manage, mentor, and grow a multidisciplinary team of backend and integration engineers. You will conduct regular 1:1s, set clear development goals, and foster a culture of continuous feedback, psychological safety, and technical curiosity.

Drive Technical Excellence: Own the lifecycle and health of our B2B integration domain. You will guide architectural decisions to ensure our product ingestion, order relay, and return pipelines are scalable, resilient, and observable.

Partner with Product: Collaborate closely with Product Managers to translate business requirements into a robust technical roadmap. You will help prioritize the backlog, balancing new feature delivery with crucial technical debt management and infrastructure scaling.

Champion Best Practices: Act as a standard-bearer for modern software development life cycle (SDLC) practices, advocating for CI/CD, test automation, site reliability, and agile methodologies across the engineering organization.

Scale the Team: Actively contribute to talent acquisition, interviewing, and building comprehensive onboarding plans to attract and retain top-tier engineering talent.

Who You Are
An Experienced Leader: You have a proven track record of managing and developing high-performing, multidisciplinary software engineering teams.

A Domain Expert in Integrations: You have deep technical experience building and scaling high-throughput integration pipelines, B2B data exchanges (APIs, Webhooks, EDI), and event-driven architectures.

Technically Grounded: While you may not code every day, you are a capable technical reference who can review architecture and guide teams using modern, cloud-native technology stacks. You have a strong background in distributed systems, asynchronous processing, and technologies relevant to our ecosystem (e.g., modern .NET, Node.js/TypeScript, Kafka/RabbitMQ, NoSQL databases like Cassandra or MongoDB, and Cloud infrastructure).

An Agile Practitioner: You have a solid understanding of agile product development and the DevOps mindset, taking ownership of software from inception through to production and continuous monitoring.

A Master Communicator: You possess the emotional intelligence and communication skills to build strong relationships with various stakeholders, bridging the gap between highly technical concepts and business outcomes.

Education: You hold a degree in Computer Science, Information Systems, or have equivalent real-world experience demonstrating a deep foundation in software engineering principles.
