Use your finance skills to support Feba’s mission and growth strategy to inspire more of the world’s least reached people to follow Jesus.
About us
At Feba, we are passionate about God’s mission and the creative use of radio and audio media to inspire people to follow Jesus. We have a particular heart for people in contexts considered closed, where people might not hear the gospel by any other means or where it’s difficult to be a Christian. These people probably won’t be reached without us, and radio and audio media provide a way of reaching them at scale.
About our development
Since we were established 65 years ago as a shortwave radio ministry much has changed with big shifts in technology, missiology and geopolitics.
We no longer operate radio infrastructure or ‘send’ missionaries from the UK. Instead, we support local people with training, expertise and funding to produce culturally appropriate programmes in a listener’s ‘heart language’ - and to follow up in-person wherever possible.
Our locally-led approach, in line with best-practice in Christian mission, is having greater and more enduring impact, and has enabled our work to expand far beyond our original focus on South Asia to countries across Africa, Asia and the Middle East.
About the role
Feba now seeks a Head of Finance and Financial Strategy to provide financial leadership and forward-thinking strategic input at a time of stability, financial strength and planned growth. This role will lead on reviewing and modernising financial processes and systems, developing and delivering strategic initiatives for good financial stewardship, planning new income-generation projects and helping to strengthen long-term financial sustainability beyond the next 10 years.
About you
We are seeking a strategically minded finance leader to bring new skills, rigour and energy to the management and oversight of our finances. You will bring knowledge of investment principles, strong technical accounting expertise, and a clear understanding of modern, effective financial systems and processes. You will be a committed follower of Christ and passionate about global mission.
If this sounds like you we would love to hear from you. For more details including how to apply please see the appointment details attached.
Closing date 3rd December.
Thank you!
