Application Support Engineer

ROLE OVERVIEW We are looking for a sharp, resourceful Application Support Engineer to own our portfolio of business applications — and grow well beyond it. You will start by becoming the internal expert on critical legacy systems, then use that deep knowledge as a launchpad: modernising infrastructure, shaping our tooling strategy, and building the technical foundations that replace what you inherit. This is a role for someone who enjoys detective work today, but wants to be an architect tomorrow. KEY RESPONSIBILITIES Application stewardship: Own a portfolio of legacy business applications — managing access, system health, and continuity for mission-critical tools. Proactive maintenance: Lead SSL renewals, server migrations, and patch management with a zero-downtime mindset. Root-cause troubleshooting: Diagnose application failures using logs, database queries, and systematic analysis — especially where documentation is absent. Modernisation input: As you master each legacy system, identify migration opportunities and contribute to the roadmap for replacing or upgrading aging infrastructure. Knowledge creation: Build the internal knowledge base from scratch — turning undocumented "black-box" systems into clear, maintainable documentation. Vendor & stakeholder coordination: Act as the technical point of contact for vendors, holding them to SLAs and translating complex issues into clear business language. Tooling & automation: Once stable, look for opportunities to automate repetitive support tasks using scripting, APIs, or AI tooling — freeing yourself for higher-value work. THE IDEAL CANDIDATE The "figure-it-out" factor: You enjoy opening a black box to see how the gears turn — and then documenting what you found so no one has to figure it out again. Tech versatile: Comfortable across different stacks, UI styles, database types, and hosting environments. You adapt fast. Growth-oriented: You see legacy support as a starting point, not a ceiling. You're drawn to roles where deep expertise becomes leverage for something bigger. Independent & communicative: You operate well with thin in-house knowledge, but know when to bring others in and can translate technical complexity for any audience. TECHNICAL SKILLS & QUALIFICATIONS Deep understanding of how web applications, servers, and databases interact Experience with logs, browser dev tools, and SQL queries for troubleshooting Knowledge of SSL/TLS certificate management and Identity & Access Management (IAM) Comfort using AI tools, OSINT, and developer forums for obscure problem-solving 3+ years in Application Support, Systems Administration, or a generalist technical role WHY JOIN US Real ownership from day one: You won't be a small cog. You will be the resident expert on systems that keep the business running — with the autonomy to match. A genuine growth path: Mastering our legacy stack gives you rare institutional leverage. The natural next step is shaping what replaces it — and we want you in that conversation. Intelligence over scripts: No ticket queues. No script-following. This role rewards curiosity, creative problem-solving, and the kind of thinking that finds answers when none exist. Work with modern tools on old problems: Bring AI, automation, and modern observability practices to a space that desperately needs them. Your methods will be current even when the systems aren't.
