Malan said he would look back at his time in Irish cricket with “great affection” and he believes it is the right time to leave the role.
“It has been an absolute privilege to work with these players, staff and the wider Irish cricket community,” said Malan.
“Thank you to the players, coaches and staff for believing in our shared vision – it has been a very special journey.”
West said Malan had made an “outstanding contribution” throughout his tenure.
“Over recent months, we have been discussing the upcoming World Cup Qualifier cycle and what would best support the squad’s preparation,” he said.
“In those conversations, Heinrich expressed a desire to step back at this point, which aligned with our focus on ensuring continuity heading into that campaign.”
West added that Malan has shown “great dedication” in his time with Ireland, and leaves good foundations to build off in the future.
“He joined us at a challenging period and has played a key role in progressing the Ireland Men’s set-up – from World Cup qualifications to historic Test wins, and in developing the depth of our playing group.”
“Through his leadership, he has worked hard to increase the depth of playing talent within the Irish system, which will benefit the squad immensely over the coming months and years.”
