Role Description We’re looking for a Senior Software Engineer who wants to be part of building that, not watching it happen from the sidelines. - At Gecko, ownership is real. You won’t be handed a neat corner of the codebase and left to maintain it. - You’ll design complex systems, lead technical refinement, and take services through to production knowing the decisions you make will still matter months after launch. - You’ll help set and hold engineering standards, mentor engineers earlier in their careers, and write down the why behind technical decisions. - From time to time you’ll get close to the people actually using what we build. Qualifications - Solid senior engineering experience in a product environment that moves fast, makes pragmatic calls, and keeps shipping. - Strong backend fundamentals and ability to reason through complex systems. - Experience with PHP/Laravel is a plus, but instincts matter more than current language. - Curiosity about AI and practical application in workflow and problem-solving. - Ability to collaborate well with Product and challenge assumptions constructively. Requirements - Experience using AI in your workflow, not just a vague interest. - Comfortable with pace and shifting priorities. - Ability to communicate when something shouldn’t be built and back it up. Benefits - 33 days holiday, an optional compressed four-day week, and flexible working that means something in practice. - 34 hours work week, not 40. - Fully remote with a proper home office setup, MacBook Pro, and headphones of your choice included. - Workation policy: Take your work somewhere worth going. - Private healthcare, pension, death in service, and EAP. - Employee benefits via Perkbox. - A collaborative and fun virtual office environment.

Role Description Harness Software Engineering Insights (SEI) is where engineering meets engineering intelligence. As part of this team, you’ll work on a deeply technical product that connects to 40+ developer tools like Jira and GitHub, processes millions of events, and turns raw SDLC data into actionable metrics. This is a product that engineers build for engineers, where you’ll see your work directly impact how thousands of developers build software. Expect challenges in data modeling, systems design, developer UX, and secure cloud integrations — all to help engineers and leaders build faster, better, and smarter. - Design, develop, deploy and maintain critical software in a fast-paced quality conscious Java environment. - Author software functional specifications and design documents for features developed. - Quickly understand complex systems/code and own key pieces of the system, including the delivered quality. - Work in an agile environment, using iterative development cycles and a short customer feedback loop. - Design and implementation of scalable backend software solutions. - Diagnose and troubleshoot complex problems in a distributed computing environment. - Perform peer reviews of specifications, design, and code. - Work alongside Site Reliability Engineers/DevOps and cross functional teams to deploy software or diagnose/troubleshoot any production related issues. Qualifications - 8-10+ years of experience developing highly scalable, distributed applications, products, and backend services using Java. - A desire to build products that solve complex technical problems for end users. - Experience with relational databases like MySQL, PostgreSQL. - Experience with SQL query tuning, performance optimizations is a plus. - Experience with search frameworks like Elasticsearch, SOLR is a plus. - Experience with applications hosted on AWS/Azure/GCP is a plus. - Familiarity with Docker and CI/CD processes is a plus. - Deep understanding of how distributed resilient software is built and deployed. - Excellent problem solving and debugging skills. - Experience working in short release cycles. Requirements - Ready to Build Something Engineers Love. This is your chance to shape the systems that shape how software gets built. Benefits - Competitive salary. - Comprehensive healthcare benefits. - Flexible Spending Account (FSA). - Employee Assistance Program (EAP). - Flexible Time Off and Parental Leave. - Quarterly Harness TGIF-Off / 4 days. - Monthly, quarterly, and annual social and team-building events. - Recharge & Reset Program. - Monthly internet reimbursement. - Commuter benefits.
