Thought Machine

Thought Machine runs a single internship programme rather than a separate graduate scheme: a 10-week placement each July to September, based in its London office, open to students in the penultimate or final year of study. Most places are in software engineering, but the firm has also placed interns in Finance, Client Delivery, Business Analyst, Partnerships, Communications, Business Development and the COO Office. Each intern is paired with both a manager and a separate buddy, and takes ownership of a scoped project intended to continue after the internship ends. Thought Machine does not guarantee a graduate offer a year ahead of the internship; interns who want to convert instead go through a review of internship feedback and an informal meeting with a manager, with no further formal interview.

With one annual intake concentrated into a single ten-week window in one city, a candidate gets a single shot per year rather than a rolling or multi-city pipeline, and the non-engineering tracks compete for a small minority of a class dominated by software engineering places.

Thought Machine passed $100m in annual revenue for the financial year ending December 2025, up 57% year-on-year, and its most recent revenue announcement states the company now holds more tier-1 bank core-banking contracts than all other next-generation vendors combined, across 68 banks and 18 of the world's largest banking institutions. Several of those tier-1 clients, including JPMorgan Chase, Lloyds Banking Group and Standard Chartered, are also equity investors in the company. To support this growth, Thought Machine has committed to hiring more than 100 additional engineers in 2026 across its London headquarters and a new Lisbon engineering office.

For an engineering-track applicant, that hiring commitment sits alongside genuine production scale: the codebase a new hire joins already runs live workloads for some of the largest banks in the world, and headcount is expanding rather than holding flat, unlike at a smaller or pre-revenue vendor.

Not right now. Thought Machine has no internship or graduate roles listed today; new postings appear here as the firm opens them.

Applications to Thought Machine go through the firm's own careers site, one application per posting, each expecting a CV and cover letter written for that role.
