We didn't pivot to innovation; it's how we've always operated. What that means for the people who work here is real: genuinely complex problems to solve, the technology and resources to tackle them properly, and the kind of scope that's rare in established businesses.\nThe bar is high - bring a curious and forward-thinking mindset and we'll give you the platform to define what comes next.\nJoin us at IG - the future gets built here.\nYour team\nWe’re looking for a Staff Engineer to push hard on AI across Brokerage Services engineering: AI-assisted coding, testing and deployments, defect triage and observability, and the internal tooling that connects our AI tools safely to Jira, GitLab, and our CI/CD pipeline. This is a hands-on, cross-team role. You’ll build tooling yourself, and you’ll raise the bar for how aggressively every team in the group adopts it.\nYour role in the Team’s Success\nThis role suits experienced engineers with a deep grounding in software engineering practice: test-driven development, pair programming, and full ownership of systems from design through to production support, in a mature Java or a comparable backend service ecosystem at scale. You should be someone other engineers already come to for technical judgement. We want people who write their own tests, review their own designs, and catch their own defects, and who use AI to extend that excellent practice further and faster.\nOur ambition: engineering that runs itself\nThe long-term goal is a pipeline where AI agents handle the bulk of coding support, testing, and triage end-to-end, largely unattended, with engineers stepping in for genuine judgement calls and exceptions. We’re early on that path today, and we want someone in this role who treats the destination as real and pushes the group toward it deliberately.\nWhat you’ll do\nDesign, build, and maintain internal tooling that embeds AI into day-to-day engineering work: coding assistants, AI-assisted test generation, deployments, and defect triage.\nBuild observability into the AI-assisted pipeline itself, so every stage shows what the tooling is doing, catching, and missing.\nIdentify the manual steps in coding, testing, and release that can run largely unattended, and build the automation to get there.\nSplit work into small, releasable pieces that ship continuously.\nWork closely with a product person on one of our product domains, so what you build is grounded in real delivery.\nTreat improving ways of working and driving AI adoption as a fundamental, ongoing part of delivering value.\nPartner with the test and PM function to bring AI into the testing pipeline: exploratory test generation, defect clustering, flaky-test detection, and smarter prioritisation of what to test.\nEvaluate, pilot, and roll out LLM-based developer tools, for example Claude Code and similar, integrating them safely with our Jira, Confluence, and GitLab environments.\nSet standards for responsible AI use in the SDLC: data handling, prompt hygiene, and guardrails around production and customer data.\nMentor engineers across Brokerage Services on effective use of AI tooling, and act as the go-to technical authority on AI-assisted engineering practice.\nWork with security and compliance to make sure AI tooling meets IG’s regulatory and data-handling requirements.\nDefine and track the metrics that show whether AI tooling is helping: cycle time, defect escape rate, test coverage, delivery turnaround. Iterate based on what the data shows.\nWhat you’ll need for this role\nSignificant experience as a senior or staff-level engineer, with a track record other engineers can vouch for.\nDeep, hands-on expertise across our backend service ecosystem, at the level of designing and owning shared service architecture.\nDeep fluency in test-driven development and pair programming as working disciplines.\nFull-lifecycle ownership: you’ve designed systems, built them, deployed them, and carried the pager for them in production.\nA genuine appetite for aggressive automation. You are energised by removing manual steps entirely.\nExperience evaluating or building with LLM-based developer tools in a real engineering environment.\n\nPreferred\nExperience with MCP, agentic tooling, or Spec Driven Development.\nFamiliarity with the Atlassian ecosystem (Jira, Confluence) and its APIs.\nPrior experience in financial services, trading platforms, or another regulated, high-reliability environment.\nThe Perks\nIt really is more than a job. We think like a start-up, but we deliver like a FTSE 100 - so the bar is high, and we won't pretend otherwise. We work hybrid, which means three days in the office. We’ll recognise your talent and make sure that you can still have a life - at work, and outside of it. Networks, committees, awards, sports and social clubs, mentorships, volunteering opportunities, extra time off… the list goes on.\nCompetitive salary\nFlexible Benefits Package on top of your salary (12%)\nPrivate medical cover for you and your family\nLife insurance\nContribution to gym memberships\n25 Days holiday, with 1 additional day off to celebrate your Birthday & 2 additional days off a year for voluntary work (28 in total)\nThe option to buy or sell holiday days\nA comprehensive global and local onboarding process\nEnhanced primary (maternity), secondary (paternity), and shared parental pay and leave, as well as a range of support and benefits for parents\nLearn more about the Perks here!\nNumber of openings\n1","description_format":"text","description_chars":5707,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Gym membership","Life insurance"],"hiring_locations":[{"name":"United Kingdom","iso":"GB","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Customs Brokerage","Online Brokerage & Trading Platforms","Forex & CFD Brokers"],"lifecycle":[{"event":"open","at":"2026-10-20T11:10:07Z"}],"visa":[],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":0,"expected_fill_days":12,"reasons":["conf:3","win:early"],"computed_at":"2026-10-20T19:57:41Z"},"pay":null,"html_url":"https://alion.io/job/ig-staff-engineer-brokerage-services","json_url":"https://alion.io/job/ig-staff-engineer-brokerage-services.json","meta":{"generated_at":"2026-10-20T19:57:41Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":23065,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-21T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":38407},"rest":"https://alion.io/mcp/rest/get_company?id=38407"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fig-staff-engineer-brokerage-services"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fig-staff-engineer-brokerage-services"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fig-staff-engineer-brokerage-services"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/ig-staff-engineer-brokerage-services\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fig-staff-engineer-brokerage-services"}]}
