JOB DESCRIPTION
Build great software:
Analyze requirements, translate them into technical specifications, and estimate their implementation cost.
Be a strong individual contributor, actively writing (or teaching AI how to write) high-quality, maintainable, and scalable code.
Contribute to the technical roadmap:
Identify and prioritise problems, gaps and technical debt in the product.
Research and evaluate new tools, technologies and frameworks to enhance the product and improve development efficiency.
Actively ensure the product is technically prepared for future challenges, especially considering security, maintainability, and scalability.
Co-own the product:
We emphasize the culture of ownership, so our engineers are empowered and encouraged to provide product development suggestions.
Provide technical input and insights to Product Managers regarding tradeoffs between scope, engineering capacity, and time constraints.
Raise the quality bar for the team:
Champion best practices and actively participate in code and design document reviews to ensure high quality.
Mentor and support other engineers, fostering their growth and development.
Cross-team collaboration
Maintain communication with other technical teams to avoid duplicate effort, incompatible solutions and solving problems other teams have already resolved.
JOB REQUIREMENT
Architecture & Modernization
Language Mastery & Transition: Possessing 5+ years of professional experience building complex enterprise web applications. You have deep expertise in PHP, but you are future-focused: you will play a key role in transforming our legacy PHP codebase into modern services powered by Golang.
Event-Driven & Async Communication: You have deep experience implementing Event-Driven Architecture to decouple systems. You are proficient with message brokers-specifically AWS SQS (our primary driver) and Kafka-to orchestrate complex workflows between services.
Legacy Transformation: You have a proven track record of modernizing legacy systems. You know how to strangle a monolith and migrate functionality without breaking the existing business logic.
Design Mastery: You hold a mastery of OOP and SOLID principles and apply Domain-Driven Design (DDD) to organize complex logic effectively.
Operational Excellence & Quality
Observability First: You understand that code isn't "done" until it's observable in production. You implement comprehensive logging, distributed tracing, and monitoring strategies to ensure system health and facilitate rapid debugging.
Quality & Root Cause Focused: You go beyond basic metrics to focus on deep structural issues. You are willing to dig deep in search of root causes to ensure long-term system health rather than applying quick patches.
SDLC Expert: You possess a high-level understanding of the entire software development lifecycle, from requirement gathering down to deployment pipelines and infrastructure.
Collaboration & Leadership
API & Interoperability Specialist: You have experience designing clear, backward-compatible, and future-proof APIs. You are comfortable using gRPC for high-performance inter-service communication, as well as standard $1ESTful API practices.
Technical Team Player: You are able to make sound technical decisions, resolve technical conflicts within your scope, and effectively mentor other engineers through the technology transition.
Clear, Concise Communicator: You possess a high signal-to-noise ratio. You can communicate and collaborate effectively with engineers and non-technical audiences alike.
Proactive Problem Solver: You identify and troubleshoot technical challenges, using architectural foresight to avoid them before they reach production.
Our Tech Stack
Core Backend & Transition: We are currently running PHP (Laravel 11.x) and actively migrating performance-critical components to Golang. We also utilize Python and TypeScript where appropriate.
Infrastructure & Cloud: AWS (focusing on SQS & EventBridge for async workflows, S3), Docker, Kubernetes, and ArgoCD for GitOps deployments.
Data & Search: MongoDB, Elasticsearch, and DataBricks.
Observability: Grafana and Prometheus for real-time monitoring and metrics.
Bonus Points
Experience with working with strongly structured languages (java, kotlin, C#)
Experience with cloud solutions (GCP, AWS)
Front-end experience (React, Typescript)
Experience or having domain knowledge in online payment, eCommerce, credit card processing, risk management, or fraud detection
