Try to work with headhunters, not ideal and a lot of shady things in this space but if you find a good one go with her/him... I work for a competitor and I just hired a guy in his early 60s. A good headhunter will help you adjust your resume and may pitch you to companies/gigs that are more open to hiring folks closer to retirement. I have a hard time placing older folks in growth roles as it often takes many years to develop resources, yet there are many roles that do not require growth and extensive training and you may be a match...
I am in my mid 40s and have been managing people for a while now - 55+ folks are more reliable, less expensive, less choosy/picky and in general much easier to manage - so do not assume that you are in a difficult situation due to your age in all situations. Where I sometimes see challenges has to do with lack of technical skills and lack of energy - if you are decent in those two areas in you are in good shape, something somewhere will click.
