Full job description

Arctic Lake, a small London company that builds trading technology for tier-one banks, offers a 3 to 6 month on-site software engineering internship for current computer science students. Interns are likely to work on one of four areas: its low-latency trading engine, FPGA hardware acceleration, distributed-ledger products, or internal developer tooling, with exposure ranging from bare-metal optimisation to application logic. Pay is stated as 50,000 pounds a year pro rata, with 25 days of holiday, weekly team lunches, snacks and an annual retreat abroad, and the firm points to a route to a permanent job after graduation. The application starts with a form and CV, then a two-hour technical challenge written in Java, a 45-minute first round, a one-hour pair-programming session, a one-hour cultural interview, and an offer. The advert explicitly states that visa sponsorship is available for this role and that it is seeking talent from anywhere in the world. No closing date or intake year is given, so the role is treated as rolling.
