The Newcastle-based firm is looking to fill 30 new roles - taking its workforce beyond 90 - and will host an open event this evening to meet potential new employees.
The news comes ahead of a busy 2017 in which the company’s annual turnover is likely to grow by £2m to £5.5m following a string of global contract wins.
Recent months have seen the company win contracts with two global banks, one headquartered in New York and the other in London, as well as a UK-wide insurance firm, HMRC and the NHS.
Opencast specialises in developing enterprise software for global businesses and on the digitisation of government data and services.
The company was founded in 2012 by entrepreneur Mike O’Brien, who has since been joined at the helm of the firm by MD Carl Shovlin, head of client services Steven Lumley and Fiona McDonald, head of technology.
O’Brien said: "Demand has been highest for software for government departments and also financial services firms," he said. "The calibre of our staff and the cutting-edge development processes we use have been instrumental in our success."
Carl Shovlin added: "Over recent years, our clients and the larger consultancies have realised that collaboration with smaller, more agile software businesses is a key part of the hugely complex process of delivering enterprise technology projects and change.
"Opencast uses a model which is an ideal fit for clients in the ever-changing, fast-moving enterprise technology environment."
The company is now recruiting for a number of positions, including software developers, scrum and agile experts, testers and project managers.
