To achieve this, we have developed the foundations of modern banking through core and payments technology which run natively in the cloud. What we are attempting is hard and means we need great people working together to build great technology.\nWe have grown rapidly in the past few years - growing our team to more than 550 individuals across offices in London, New York, Singapore, Sydney and our newly established Engineering Hub in Lisbon. We have raised more than £500m in funding and our investors include Molten Ventures, Eurazeo, Intesa Sanpaolo, Temasek, Nyca Partners, JPMorgan Chase Strategic Investments, Standard Chartered Ventures, and more.\nWe have created a culture that enables our team to produce the best work in the industry while ensuring we have fun along the way. We're regularly cited as having a fantastic workplace culture and have been recognised by Sifted magazine as having one of the highest Glassdoor ratings for a UK fintech company and the industry's most generous employee share package. Named one of the world's most innovative fintechs by Global Finance Magazine, we were also recognised by the Financial Times as one of Europe's fastest-growing companies for two consecutive years-and a UK Best Employer for 2026.\nAs a Senior Software Engineer II, you operate with a wide sphere of influence. You will own complex, highly ambiguous technical challenges end-to-end, handling unexpected hurdles independently and gracefully.\nYour role goes beyond individual team delivery; you will drive systemic, organizational change and shape the long-term technical direction of our platforms. You will actively drive our engineering and company principles by aligning with our broader codebase, architecture, objectives, and goals, while acting as a crucial link between senior leadership, external stakeholders, and engineering teams.\nWhat You’ll Do\nTechnical Leadership\nDesign & Build: Create solutions to highly complex problems, utilising a deep understanding of the codebase and architecture, and lead the direction for future technical change.\n\nArchitecture & Standards: Utilise expertise to enable solutions to meet security, performance, cost, reliability, maintainability, and scalability requirements in a repeatable way and beyond existing capabilities, shaping the overall technical direction. Take part in defining standards and engineering practices for the entire company. Drive adoption of latest technologies, such as AI-tools, to scale developer velocity and code quality, keeping Thought Machine always ahead of the curve.\n\nTechnical Direction: Keep a pulse on industry-leading software trends and best practices, introducing new tools and processes that shape Thought Machine's technical roadmap.\n\nCode Quality & Peer Review: Provide technical leadership and guidance to support others, ensuring their work items consider broader impact, long-term outcomes, and strategic direction end-to-end.\n\nOperational Excellence: Investigate complex issues spanning across services in non-local or production environments (including across environments, clusters, and products), and possess a deep understanding to drive improvements to operational and production support processes.\n\nHiring: Lead technical interviews to actively evaluate the capability of Subject Matter Experts (SMEs) and leadership roles..\n\nProduct & Delivery\nEnd-to-End Ownership: Own the solution to work items of undefined scope and high complexity end-to-end, handling unexpected complexity gracefully and independently. Drive delivery requiring effective and timely stakeholder management across larger milestones, which can potentially span multiple units or departments.\n\nProduct Vision: Utilise a deep understanding of the product to envision and contribute to future solutions, plans, and approaches. Drive the direction and actively contribute to the product strategy, vision, and long-term roadmap.\n\nCollaboration & Mentorship\nStrategic Communication: Communicate seamlessly with stakeholders at all levels, managing leadership expectations while preserving the agility and focus of engineering teams. Build consensus, and enable solutions to complex, changing requirements\n\nTeam Growth: Inspire and empower others by example and through your guidance, knowledge sharing, and idea creation. Understand the capabilities and expertise of others to enable effective delegation and personal growth. Empower, inspire, and delegate effectively to senior engineers, fostering an environment of technical excellence and continuous growth.\n\nWhat We’re Looking For\nTechnical Expertise and Leadership: Deep expertise in modern backend languages (ideally Go/Python) and large-scale, cloud-native systems. A proven technical leader who champions industry best practices, mentors peers, and drives the delivery of solutions to highly complex problems.\n\nProblem Solving: A proven ability to solve highly complex problems of undefined scope, utilising your expertise for decision-making that actively influences the strategic direction of the department.\n\nProduction Operations: Extensive experience investigating complex issues across multiple environments, clusters, and products, with a demonstrated ability to drive systemic improvements to operational and production support processes.\n\nEgoless Collaboration: A visionary mindset that does not accept the status quo. You are receptive to new ideas, able to see how different approaches can be combined advantageously, and focused on finding solutions that improve company and client outcomes.\n\nCommunication: Exceptional communication skills with the capability to provide leadership across a variety of stakeholders, drive organisational change, and set the direction for how engineers operate with technical excellence.\n\nBenefits\nHighly competitive salary\n\nPension plan (match up to 5%)\n\nLife insurance - three times annual salary\n\nCompetitive maternity (six months fully paid) and paternity leave (four weeks fully paid)\n\nShared parental leave (matched to our maternity leave for the same point in time)\n\n25 days holiday and bank holidays\n\nFlexible working hours\n\nCycle-to-work scheme\n\nElectric car scheme\n\nSeason ticket loan\n\nAccess to outstanding learning materials and courses\n\nSports and hobby clubs, subsidised by Thought Machine\n\nAll the latest tech you need\n\nStart the day properly with fresh fruit and cereals\n\nHuge range of healthy (and not-so-healthy) snacks, smoothies and drinks\n\nA talented and experienced team as your colleagues\n\nAn environment where we encourage learning and progress\n\nTwo charity days a year\n\nWeekly food pop-up\n\nWe actively hire candidates who demonstrate technical excellence in their field and welcome people of all ages and backgrounds, providing everyone with equal access to professional development. You are encouraged to apply even if your experience doesn't accurately match the job description. We also encourage applications from those with different abilities, including candidates with ADHD, autism, dyslexia or dyspraxia.","description_format":"text","description_chars":7132,"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":["Flexible schedule","Life insurance","Parental leave","Professional development"],"hiring_locations":[{"name":"United Kingdom","iso":"GB","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Financial Software & Embedded Finance"],"lifecycle":[{"event":"open","at":"2026-07-16T16:40:03Z"}],"visa":[{"country":"GB","licensed_sponsor":true,"evidence":"Licensed UK visa sponsor (Skilled Worker)","filings_12m":null,"filings_prev_12m":null,"green_card_filings_12m":null,"median_offered_wage_usd":null,"route":"Skilled Worker","cap_exempt":false,"checked_at":"2026-10-31T06:23:40+00:00","sources":["UK Home Office: register of licensed sponsors (workers)"],"filings_for_role_12m":0}],"liveness":{"score":31,"band":"fade","label":"Fading","p_open":1,"p_active":0.714,"p_room":0.44,"age_days":107,"expected_fill_days":75,"reasons":["conf:1","win:tail","crowd:"],"computed_at":"2026-11-01T06:10:25Z"},"pay":null,"html_url":"https://alion.io/job/thought-machine-senior-software-engineer-ii-2","json_url":"https://alion.io/job/thought-machine-senior-software-engineer-ii-2.json","meta":{"generated_at":"2026-11-02T03:30:05Z","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":5229,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-03T00:00:00Z"}},"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":7206},"rest":"https://alion.io/mcp/rest/get_company?id=7206"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fthought-machine-senior-software-engineer-ii-2"},{"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%2Fthought-machine-senior-software-engineer-ii-2"},{"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%2Fthought-machine-senior-software-engineer-ii-2"},{"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/thought-machine-senior-software-engineer-ii-2\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fthought-machine-senior-software-engineer-ii-2"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":71376}},{"tool":"search_jobs","arguments":{"company":"thoughtmachine.net","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":71376},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
