Senior Software Engineer

Sophia is Isazi's next-generation intelligent document processing platform, built to help clients automate, scale, and optimize the way they work with unstructured data. The Sophia team combines software engineering, AI, and user-centered design to deliver powerful, production-ready solutions for enterprises that need accuracy, speed, and adaptability in their document-heavy workflows.

Joining the Sophia team means you'll be working at the intersection of AI, automation, and full-stack engineering. You'll collaborate with data scientists, product managers, and client teams to design, deploy, and evolve core components of Sophia — from AI-driven document classification to workflow orchestration — all with a focus on solving real business problems.

What you'll be doing

• Designs and delivers solutions with an AI-first mindset, leveraging data-driven and intelligent systems to solve complex problems.
• Leading the design, development, and deployment of AI-driven software solutions within the Sophia platform.
• Building and maintaining scalable, testable full-stack code (Golang, , PostgreSQL, cloud-based and containerised environments)
• Architecting and optimizing production systems, which incorporate AI at many levels e.g. a document enabled workflow automation platform.
• Familiarity with incorporating AI-driven automation or optimisation solutions (e.g., container packing, document-template matching) is a plus.
• Partnering with cross-functional teams (engineers, data scientists, product managers, and business stakeholders) to solve client challenges.
• Overseeing delivery for a small development team, while conducting code reviews, mentoring juniors, and guiding the technical direction of Sophia's engineering work.
• Ensuring adherence to SDLC best practices and agile methodologies, balancing speed with robustness.
• Contributing thought leadership on AI integration, model deployment, and scalable software design.

Who are you?

• Experienced: 6+ years of professional software engineering experience, with proven success building and deploying AI-based products and solutions.
• Educated: A strong academic background, ideally with a BSc Computer Science in or equivalent — distinction-level performance a plus.
• Leader: You've led projects or teams, showing initiative, ownership, and the ability to question assumptions rather than just execute tasks.
• Problem Solver: You thrive on designing elegant solutions to complex challenges and are comfortable working across the full stack.
• Agile Practitioner: Hands-on experience with agile methodologies (scrum/kanban), with a track record of delivering in iterative environments.
• AI Enthusiast: You're passionate about applying AI and machine learning to solve real-world business problems.
• Communicates complex systems and ideas with clarity across technical and non-technical teams.
• Collaborator: You value teamwork, open communication, and sharing knowledge to grow those around you.
