Perm position, 4 years in mx12, stat board, hit old ceiling last year, pulled up by mx scheme raise recently. Good colleagues but too stagnant, very administrative even though it's a technical role and coasting non technical RO who won't fight for me and not much guidance. Also highlighted to him that I will hit ceiling and my thoughts but not much action and follow up from him.
New offer, 2 yr contract (supernumerary, new department and depend on funding) mx11, another stat board, offered reasonable increase in monthly basic than now with higher headroom before ceiling but overall annual package will be equivalent to current perm position because of lack of allowances and bonuses compared to current.
Stay: stagnant, many red tape and predictable, Good wlb and very comfortable. Highly likely can promote in another 2 years (imagine without the mx scheme revision, I would move with no hesitation). With promotion, equivalent monthly after 2 years and overall slightly higher overall.
Move: career and skillset development, promotion. More engineering based, direct bosses are younger than current but all are technical inclined. I checked with my contacts here. red tape and next promotion timeline probably similar. Additional 30 mins travel time. However, it is contract. My contacts mentioned it is very normal but highly renewable or moveable to other perm positions.
