Hi there! I have a few characters who could work as possible connections 
Freddie Prewett works in the Apparition Testing Centre, so they're not quite coworkers but work in the same department. He's a bit younger than Aidan, but not so young that they couldn't be friendly.
Edric Umbridge is about five years older than Aidan, another MCPB, and heads the Department of Magical Accidents & Catastrophes in addition to being a member of the Wizengamot. He's not a social butterfly sort and prefers the company of his close friends and his wife, but he's a hardworking employee. He was formerly head auror, but transferred out when he and his wife started their family.
Simeon Shafiq is around Aidan's age, is an UCPB, and is the assistant head of the Investigation department. He's a very no-nonsense boss to his employees, but is much warmer with people he considers his friends.
Delight Urquart works in the Department of Magical Accidents & Catastrophes, is the daughter of the former Minister for Magic, and prefers the company of the women in her department to any of the men she works with. She's a sunny soul, but after scandals her family has faced in recent years she's begun to put up an emotional wall.
I also love stamps, but I don't have any magical creatures or ghosts D:
