About

We are seeking a Senior Software Engineer (Backend) to join our Integrations domain. Our mission is to develop the industry's most robust and scalable integrations platform, ensuring seamless data flow between Lokalise and the hundreds of tools our customers utilize daily, including code repositories, design tools, and content management systems.

This role involves not only building integrations but also architecting a platform that simplifies customer workflows and enhances developer efficiency. As a senior team member, you will be a standard-setter and a force multiplier, leading by example, elevating our craft, shaping technical direction, and contributing to a world-class engineering environment.

You Will

• Architect and Own: Lead the design, development, and long-term ownership of our core integrations platform and services, balancing velocity with long-term maintainability.
• Think Holistically: Understand customer workflows and business impact beyond code, grounding technical decisions in clear value delivery.
• Build the System: Champion and implement practices to improve the entire development lifecycle, building automated pathways to production and using data (like DORA metrics) to enhance delivery performance.
• Elevate the Team: Act as a force multiplier through thoughtful code reviews, mentorship, and knowledge sharing, raising the skill level of engineers and fostering a culture of pride in our work.
• Lead in AI-Powered Development: Pioneer and evangelize AI development tools within the team, discovering and sharing workflows that accelerate the organization.

You Must Have

• Deep Technical Craft: 7+ years of experience building and running complex backend systems, with solid experience in Node.js and PHP, comfortable owning and evolving systems across a mixed stack of modern services and a PHP monolith.
• Integrations Domain Expertise: A proven track record in the integrations space, understanding patterns (e.g., webhooks, polling, message queues, event-driven architectures), API versioning challenges, and principles of building a scalable, multi-tenant integrations platform.
• Systems Thinking: Strong understanding of modern backend building blocks: API best practices; message queues (RabbitMQ, SNS/SQS or similar); relational data stores (PostgreSQL or similar); and cloud services (AWS or similar).
• High-Impact Judgment & Decision Quality: Demonstrated history of making sound technical judgments through research, prototyping (PoCs), and clear, written debate via technical design documents (like RFCs or ADRs), prioritizing getting it right.
• Pragmatism over Dogma: Belief that great engineering solves problems, viewing languages and frameworks as tools. Demonstrated ability to quickly learn and apply new technologies, comfortable context-switching between different parts of a complex system (PHP monolith to Node.js microservices), always focusing on the right tool for the job.
• A Commitment to Quality: Belief that testing, observability, and operational excellence are core to engineering craft.
• AI as a Core Competency: Demonstrated mastery of AI-powered development tools (e.g., GitHub Copilot, Cursor, Claude Code) and a passion for coaching others.
• Leadership and Influence: Excellent problem-solving, analytical, and communication skills, articulating complex technical ideas clearly and inspiring higher standards.

It's a Plus if You Have

• Experience building developer-facing APIs or SDKs.
• Experience contributing to or maintaining open-source projects.
• Familiarity with the localization domain and its unique technical challenges.

Our Benefits

• Competitive salary and employee stock options plan.
• Fully remote and flexible working hours.
• Co-working budget.
• Flexible vacation policy.
• Home office setup budget.
