Translation and Localization

Description

Who are we At Lokalise, we make it easy and profitable for businesses to expand into new markets. Founded in 2017, our AI-powered translation and localization platform automates workflows, integrates with over 60 tools, and helps product teams launch multilingual products 10x faster and at 80% lower cost. Trusted by thousands of businesses across over 100 countries, Lokalise is empowering more than 25 million people worldwide to use diverse services in their native languages. Backed by a customer-loved support team, our platform seamlessly fits into your design and development processes, helping you scale effortlessly. Location While our company operates exclusively on a remote basis, you must reside and have the legal right to work in one of the following countries: the United Kingdom, Latvia, or Spain. This is a full-time, remote position. Please note that we do not engage on a B2B or contractor basis. We do not partner with search firms. About We're looking for a Senior Software Engineer (Backend) to join our Integrations domain. Our mission is to build the industry's most robust and scalable integrations platform, enabling seamless data flow between Lokalise and the hundreds of tools our customers rely on every day—from code repositories and design tools to content management systems. This isn't just about building integrations; it's about architecting a platform that makes our customers' workflows effortless and our developers' lives easier. As a senior member of this team, you won't just be an individual contributor; you will be a standard-setter and a force multiplier. You will lead by example, elevating our craft, shaping our technical direction, and helping us build 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, making pragmatic trade-offs between velocity and long-term maintainability. Think Holistically: Go beyond the code to deeply understand customer workflows and business impact. Ground every technical decision in a clear "why" that connects your work to the value we deliver. Build the System: Champion and implement practices that improve our entire development lifecycle. You'll help us build frictionless, automated pathways to production and use data (like DORA metrics) to measurably improve our delivery performance. Elevate the Team: Act as a force multiplier. Through thoughtful code reviews, mentorship, and knowledge sharing, you will actively raise the skill level of the engineers around you. You'll contribute to a culture where we are all proud of how we build. Lead in AI-Powered Development: Pioneer and evangelize the use of AI development tools within the team. You won’t just use these tools; you will actively discover and share workflows that accelerate our entire organization. You Must Have Deep Technical Craft: 7+ years of experience building and running complex backend systems. You have solid experience with Node.js and PHP, and are comfortable owning and evolving systems across a mixed stack of modern services and a PHP monolith. Integrations Domain Expertise: A proven track record of working in the integrations space. You understand the patterns (e.g., webhooks, polling, message queues, event-driven architectures), the challenges of API versioning, and the 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: You see decision-making as a deliberate engineering practice, not an afterthought. You have a demonstrated history of making sound technical judgments by driving a process of research, prototyping (PoCs), and fostering clear, written debate via technical design documents (like RFCs or ADRs). You prioritize getting it right over being right. Pragmatism over Dogma: You believe great engineering is about solving problems, and you see languages and frameworks as tools to be selected, not identities to be defended. You have a demonstrated ability to quickly learn and apply new technologies, and you're comfortable context-switching between different parts of a complex system. From our PHP monolith to our modern Node.js microservices, always focusing on the right tool for the job. A Commitment to Quality: A belief that testing, observability, and operational excellence are not afterthoughts but core to the 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 in their use. Leadership and Influence: Excellent problem‑solving, analytical, and communication skills. You can articulate complex technical ideas with clarity and inspire others to adopt 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 — want a little escape from your home office? We’ve got you. Flexible vacation policy to recharge whenever you need. Home office setup budget — monitor, desk, ergonomics, whatever helps you do your best work. Learning and development budget to level up your skills and career. Health insurance to keep you covered. Wellness allowance to invest in your mental and physical well-being — gym, meditation, coaching, or whatever helps you thrive. Great startup culture — we’re remote but close-knit, with regular retreats and social events to stay connected. We are committed to a culture of inclusion and equal opportunities. Therefore, we welcome applications from people of all gender identities, sexual orientations, personal expressions, relationship, marital, or civil partnership statuses, racial identities, national or ethnic origins, religious beliefs, ages, and disability statuses.
