No, but if the OP's goal is to contribute to dmd, learning SSA wouldn't be very helpful beyond a general acclimation to compiler arcana. (Unless they wish to add SSA to dmd--a worthy goal, but perhaps not the best thing to start out with.) The backend is not where our efforts should be going. There is way too much work that needs doing above it to motivate working on the backend. The backend's design for the most part is extremely simple just buried under 40 years of code. Besides, there's more to life than dmd, everything else is SSA at least some point in compilation (i.e. GCC isn't SSA all the way down but GIMPLE is).

In addition to what others have said: there are many ways you can contribute to D without needing to know anything about compiler internals. For example, you could fix one of the many [known bugs in the standard library][1], or improve the documentation. In general, there are more things that need to be done in D than there are people with the time to do them, so any contribution is valuable.

The classic book on compilers that Walter recommends is the dragon book. https://smile.amazon.com/Compilers-Principles-Techniques-Tools-2nd-dp-0321486811/dp/0321486811 (D Language Foundation is a charity Amazon Smile recognizes). The dragon book is really really showing it's age these days so I would highly recommend getting a copy but not reading it fully. "Engineering a compiler" is much better pedagogically. The dragon book barely mentions SSA for example, although the sections they did properly bother to update towards the end are quite interesting. "Crafting interpreters" is quite good, I recommend it for learning how to actually write a parser without getting bogged down in totally useless theory. Stephen Muchnick's "Advanced Compiler Design and Implementation" is *the* bible for optimizations, but uses a very weird unimplemented language so be careful for bugs. "Optimizing Compilers for Modern Architectures: A Dependence-based Approach" is the only book I'm aware of that actually covers even the beginnings of modern loop optimizations thoroughly. Even this however is still somewhat set back by it being written 20 years ago, the principles are the same but the instinct is not i.e. memory latency is worse, ILP is much better. What all of these books have in common, by the way, is that they were all written at a time when it was assumed that x86 would go the way of the dodo. So there is a somewhat significant deviation from "theory" and practice in some parts as (say) x86 SIMD is quite different from how the authors of the aforementioned book expected the world to go.
