Works With: Engineering Leadership, Product Managers, Designers, Software Engineers Hours: 37.5 pw (9.30-6pm Monday to Friday, 1 hour lunch) Term: Permanent Location: Hybrid - London office based in Oval (2 days / week) About us Artlogic is a leading technology platform for the art world. Founded in 1989, Artlogic empowers over 6,000 galleries, dealers, and art professionals worldwide to streamline their operations and grow their businesses. The company's integrated platform combines inventory management, CRM, websites, sales, marketing, and payment tools, everything needed to run a modern and successful art business. In 2021, Artlogic was acquired by tech investors Cove Hill Partners to accelerate innovation and expand its global reach. Since then, the company has doubled in size, with employees across London, New York, Atlanta, and Cape Town. Today, Artlogic is entering an exciting new chapter through its merger with ArtCloud, another industry leader in art technology. Together, the two companies are uniting complementary platforms to build the most comprehensive, forward-thinking solution for the art world. This collaboration brings together deep expertise across CRM, sales, marketing, inventory, payments, and AI-powered tools, empowering galleries, artists, and collectors worldwide. Joining Artlogic means becoming part of a growing global team that is shaping the future of how art is bought, sold, and managed, both online and in person. Our technology team comprises over 50 people across Product, UX and Engineering working in cross-functional teams geographically distributed principally between the UK and Brazil with a technical operations team in the UK and South Africa. At present, our technology stack comprises a combination of Python, Typescript, C# in Azure, GCP and AWS cloud environments. About the role We are seeking a pragmatic, impact-driven AI-Native Senior Software Engineer to help evolve and extend our platform while guiding technical direction and supporting team development. This role centres on solving real-world problems for art professionals, making thoughtful technical decisions that balance business impact with engineering trade-offs. You will work closely with Product Managers, Designers, and engineers to take ideas from inception through to production, ensuring we build the right solutions for our customers. You will act as both a senior technical contributor and a product minded engineer, someone who doesn't just implement requirements but actively shapes them. You will challenge assumptions, ask the right questions, and help ensure we are solving meaningful problems in the most effective way. You will contribute to technical strategy by identifying opportunities to improve system reliability, performance, and user experience within our current architecture, while also supporting the evolution of our strategic platform. This role will play a key part in driving the adoption of AI across engineering, leveraging emerging technologies and embedding AI-native workflows to improve how we design, build, and deliver software. This role is predominantly hands on, with around 20-30% of time on technical leadership: architecture, mentoring, and shaping how the team works. Key Responsibilities Help the team move faster by adopting AI-native workflows and the shift to an agentic development lifecycle, without compromising the architectural qualities that make our platform reliable, scalable, and maintainable over the long term. Define guardrails, review practices, and validation gates that hold AI-generated code to our standards for security, reliability, and cost-efficiency (FinOps). These are first-class concerns in agentic pipelines, not afterthoughts. Design, build, and operate software across our platform, applying the same rigor to AI-augmented work as to anything else you ship. Embed deeply with Product and Design from the earliest stages of discovery, using rapid prototyping and iteration to compress the gap between idea and validated solution. Own complex features and ambiguous technical problems end-to-end, leveraging AI tooling to increase throughput without sacrificing engineering rigor. Serve as a critical technical voice, stress testing AI-generated solutions, surfacing second order risks, and ensuring the team builds the right thing, not just the fast thing. Shape platform architecture with an architectural lens, contributing to long term decisions about how AI tooling, LLM integrations, and human in the loop controls evolve across the stack. Continuously identify and exploit opportunities to improve performance, reliability, and user experience, using observability and analysis to find signals in noisy systems. Navigate confidently across legacy and greenfield contexts, applying AI tooling pragmatically to modernize where it matters most. Set the engineering standard, demonstrating through your own work what excellent looks like when much of the code is AI-generated. Grow the team's capability and confidence with AI-native practices, coaching more junior engineers to think critically about model outputs, prompt design, and the boundaries of automation. Define and evolve best practices for code quality, testing, documentation, and delivery in a world where much of the first draft is AI-generated. Evolve CI/CD pipelines to incorporate agentic workflows, automated testing, AI-assisted code review, and intelligent deployment gates. Champion secure by design principles across both human-written and AI-generated code, embedding security validation into the development pipeline rather than treating it as an afterthought. Own system observability and reliability, moving from reactive alerting to proactive, model-assisted incident prevention. Participate in on call rotation, bringing the same rigor to incident response that you bring to day to day development. About you You're a hands on senior engineer with a product mindset and the judgement to know which trade offs matter. You care about business impact as much as engineering quality, and you've been building with AI tools long enough to know how to use them effectively. You'll likely bring: Deep experience building scalable, secure, cloud-based systems, giving you the foundation to confidently guide and validate agentic workflow outputs. Proven ability to work across both legacy and greenfield codebases, using modern tooling to improve reliability and evolve architecture pragmatically. Strong system design fundamentals across scalability, performance, and distributed systems, including API design (REST, GraphQL). Hands on experience with observability tooling (Datadog, Grafana, or similar) and a data informed approach to system health and reliability. Solid SQL and data management skills, with an appreciation for AI enabled, data driven systems. Familiarity with CI/CD, containerisation (GitHub Actions, GitLab CI, Docker), and DevSecOps practices in modern AI development environments. A pragmatic approach to testing, knowing what to cover, what to skip, and how to use AI to improve efficiency. Experience mentoring engineers and supporting the adoption of modern tools and AI-native workflows. Strong communication skills and the ability to articulate technical decisions and trade offs clearly. You'll stand out if you: Ask "what problem are we solving and why?" before reaching for a solution. Act as a genuine partner to Product and Design, shaping the problem, not just delivering against a spec. Balance technical debt and feature delivery with long term business value in mind. Make confident decisions with incomplete information and thrive in fast moving, evolving environments. Bring curiosity and hands on experience with agentic workflows, using them to raise the bar for engineering. Performance Indicators Delivery of high quality, reliable solutions that drive measurable customer and business value. Meaningful contribution to the evolution of the strategic platform and overall technical direction. Improved technical decision making, engineering standards, and team capability. Effective mentorship and development of engineers within the team. Strong partnership with Product and Design, resulting in well shaped, high impact solutions. Improvements in system performance, reliability, and maintainability. Consistent adoption of engineering best practices and processes.
