Senior Localisation Engineer

About the company

Heidi Health builds AI-powered medical scribe and care-partner software that removes administrative burdens from clinicians.

About this role

We’re Heidi. We're building the future of healthcare by giving every clinician the earth's finest AI Care Partner. In just 18 months, our clinical AI products have absorbed the administrative chaos of 73 million patient visits. Today, we support over 2.5 million patient sessions a week across 190+ countries. Healthcare systems are failing us; clinicians spend more time on documentation than on patients, and the human connection that makes medicine worth practicing is eroding. Our mission is simple: double the world’s healthcare capacity and strengthen the human connection at its heart. We found product-market fit with a freemium medical scribe that clinicians love. Now, we're expanding. Every task a clinician hands to Heidi is a patient who feels more attended to, a health system unclogged, and a clinician who gets to be a clinician again. If you don’t choose easy and you want to build something way bigger than yourself then, choose the challenge, choose Heidi. The role As a Localisation Engineer at Heidi, you will be responsible for building and maintaining the technical frameworks that enable our products to be seamlessly localised across multiple languages and regions.   You will partner with product managers, engineers, designers, and linguists to ensure our software is internationalisation-ready, localisation processes are efficient, and the final experience is high-quality in every market.   This role is highly collaborative and technical, you’ll be the bridge between engineering and localisation, automating workflows, troubleshooting issues, and driving improvements in how Heidi delivers global experiences.   What you’ll do - Build and improve Heidi’s localisation platform and workflows, enabling our products to scale globally. - Develop AI-assisted translation pipelines that combine automation with human-in-the-loop review. - Design systems that reliably deliver localised content across web and mobile applications. - Build tools that enable linguists and product teams to review, manage, and improve translations. - Build and contribute to developer tooling and open-source libraries that simplify localisation and internationalisation (i18n) workflows. - Integrate localisation platforms (e.g. Crowdin, Smartling, or similar) into development and release pipelines. - Work with structured content formats (JSON, XML, XLIFF, etc.) and maintain clean integration with source control systems. - Partner closely with engineering, product, design, and QA to deliver a high-quality experience across languages and regions. - Identify and resolve localisation issues across the stack, from pipelines to UI/UX.   What you'll need - 3-10 years' of professional software engineering experience. - Has experience working with cloud infrastructure (e.g. AWS, GCP). - Is proficient in Python or Go and comfortable building tools and automation. - Enjoys solving practical problems and debugging technical and linguistic issues. - Communicates clearly and collaborates effectively with cross-functional teams. - Cares about product quality and delivering great user experiences across languages and regions.   Nice to have:   - Has experience with localisation platforms such as Crowdin, Smartling, or similar tools. - Familiarity with localisation and internationalisation principles. - Experience or interest in NLP or language-related systems. - Familiarity with infrastructure-as-code tools (e.g. Terraform). - Experience building internal tools or developer platforms. - Appreciation for cultural and linguistic differences; multilingual experience is a plus.   How we show up - Build for the next decade, not next quarter. Our targets are outrageous on purpose. The world's health doesn't have the luxury of incrementalism. - Lead, don't wait. We treat tomorrow's problems today. Sometimes we build what's needed before it's wanted, and we're fine with that. - Follow the evidence. Trust the patient. We pursue truth relentlessly. But when the subjective and objective disagree, we treat the patient, not the numbers. Ego is a comorbidity we can't afford. - Own the outcome. Everyone here carries the company. Raise problems with solutions, solve them end-to-end, and never be a bystander. - Ship, measure, go again. A button today, a workflow tomorrow. More iterations beat better planning. We're precise at pace, not reckless. - Live in clinicians' reality. Not the ideal workflow, the twenty-patients-before-lunch actual one. We build for exhausted humans, and we'd better be decent ones while we do it. Why Heidi? You’ll join a team focused on real-world impact over imaginary valuations and glossy PR. We live and breathe the challenges of modern health systems, and are laser-focused on exacting the change we’d like to see. We’re medicos, engineers, builders, and designers who’ve felt the moral and practical toll of what non-care feels like. True A-players progress extremely fast here. The nature of the scale-up game is demanding, but we value sustainable performance and mental health. You're trusted to perform, and you set your schedule. We operate on outcomes > inputs, not process theatre. We all take the bins out, metaphorically and literally. Building what we’re building isn’t always easy. But we didn’t choose easy, we chose to build something that actually matters. We hold ourselves to a higher standard because healthcare demands it. If you join Heidi, you recognise that the deeper question isn’t whether AI can solve the global healthcare crisis, but whose hands will shape it. The work is hard, but you will trust and admire the people you work beside, and rest easy knowing you’re doing the defining work of your career. We take care of you. We offer a $1,000 annual learning and development budget, a $150/month health and wellness allowance, a $500 home office budget, 26 weeks paid primary parental leave and 18 weeks paid secondary parenta
