## Description

Guru Pay is an EMI based in Lithuania, with a mission to deliver personalized, boutique financial services to B2B, B2C, and C2B customers. We are highly ambitious - focusing on speed, security, and top-tier quality in everything we do.

We are looking for a **Senior Full-Stack Engineer / Tech Lead** to take technical ownership of one of our core product areas, such as customer onboarding, Internet Bank, or mobile.

This is a **hands-on engineering role**. You will set the technical direction while spending most of your time designing, building, reviewing, and running production software across backend, web, and mobile.

You will work alongside an **Engineering Manager**, who owns the team, people, capacity, and delivery. You will own the **technical side of the area** - architecture, engineering quality, technical risk, and production readiness.

**What will you do?**

-   Own the **technical direction and architecture** of your product area, keeping it aligned with the product roadmap.
-   Write **production code across backend, frontend, and mobile** - hands-on engineering will make up most of the role.
-   Take on the hardest technical challenges, especially those crossing services, applications, or teams.
-   Make architecture decisions around **service boundaries, APIs, contracts, and data flows**, and clearly communicate the trade-offs behind them.
-   Set the standard for **code quality, reviews, automated testing, CI/CD, and engineering practices** across the team.
-   Identify technical risks early and make pragmatic trade-offs between **speed, maintainability, security, reliability, and regulatory requirements**.
-   Work with Product, Engineering, Platform/DevOps, Compliance, Risk, Security, and external partners to deliver solutions that are technically sound and production-ready.
-   Own **observability and production health**, participate in incidents, and ensure follow-up improvements are completed.
-   Reduce technical debt and knowledge silos, ensuring critical systems do not depend on a single person.
-   Help the team adopt **AI coding agents, automation, and shared engineering tooling** effectively.

**Our Stack**

**Backend:** PHP, Laravel, Go  
**Frontend:** React, TypeScript, Vite, Tailwind, Inertia, Storybook, Blade & Stimulus  
**Mobile:** React Native, Expo & EAS  
**Data & Messaging:** MySQL, Redis, RabbitMQ, S3  
**Platform:** Docker, Kubernetes, Azure DevOps  
**Testing & Observability:** PHPUnit, Datadog, Sentry, OpenTelemetry

**What we expect**

-   **7+ years** building and running production web systems, with experience as a Tech Lead, Lead Engineer, or senior technical owner within an engineering team.
-   Strong hands-on expertise with **PHP/Laravel and React/TypeScript**.
-   Genuine **full-stack experience** - comfortable owning backend services as well as customer-facing frontend applications.
-   Experience designing **APIs, distributed systems, service boundaries, and asynchronous architectures**.
-   Experience owning software end-to-end: from **architecture and implementation through testing, deployment, observability, and production support**.
-   Comfortable working with a **second backend language** - Go is the one that applies here.
-   Strong understanding of **automated testing, CI/CD, observability, security, and production reliability**.
-   Ability to make and clearly explain technical decisions and trade-offs to both technical and non-technical stakeholders.
-   Business-level communication fluency in English.

**Nice to have**

-   **React Native / Expo** experience, including shipping mobile apps through app stores.

-   **Extra vacation day** on your birthday
-   Flexible hybrid work from our Vilnius office or home
