What skills should I teach to the existing ones?

Question

IT education

Hello!
Dear engineers and programmers, please give feedback - what to improve and add to your existing skills so that there is a chance to get a job as a roboticist?
What I can do:
- programming on Wiring (C4Arduino), Python4Embedded (that is, "low-level" procedural Python on Linux on single-board microcomputers for "jerking" the microcomputer's legs),
- designing, assembling, debugging, changing circuits on ready-made components - Arduino, any modules and shields for them,
- microelectronics / circuitry - not very good, I can solder a circuit from a book, but no more,
- engineering graphics - I can't draw beautifully, only draft designs, some nodes without size proportions, I model in TinkerCAD (quickly, for prototypes and simple 3D models), OpenSCAD (long, for thorough 3D models),
- mechanics - I know how to work on a wood lathe (my father taught me when I was a child, I partially earned money on it for my first computer), I learned how to print on a 3D printer (from buying a whale, assembling, setting up, 3D modeling, adhesion, PLA temperature and speed modes /ABS, sanding, polishing and painting with acrylic brushes).
All this is not at a high level, because. more like a hobby and nostalgia for childhood dreams, when I read books by Lem, Clark and magazines TM, YUT to holes. My "ceiling" is a remote-controlled robot based on Arduino with ultrasonic sensors, able to slow down in front of obstacles, assembled from scratch on designed and printed plastic parts, Arduino, modules and a little "loose" microelectronics.
The prose of life is such that he dreamed of conquering space and robots, but began to work as a not very qualified copywriter and layout designer. But it is completely my fault that I could not realize my dreams, because. interest is quickly lost without "feeding", I did not really study at the university (formally - a systems engineer), there are no permanent interests and hobbies. But the hobby somehow slowly developed. Now, creating this topic, I myself understand that I have learned many things that are interesting to me "on the sly".
What is the question - I understand that with such sketchy "self-taught" skills, I am not interested in any company or startup in the field of robotics. Therefore, I ask you to tell me what I need to learn, add and bring up to a good level in order to become interesting for a potential employer?
Target- creative work in the field of robotics, better universal than specialized, with a wide range of tasks to make it interesting.
I understand that, most likely, I will not find such vacancies here, so I need to prepare to relocate to another country where high-tech manufacturing and robotics are actively developing (USA, Germany, China). That is - add English to the tasks for learning skills, as well as play the Green Cart lottery :)
Thanks for the answers everyone!

Answer 1

If "microelectronics / circuitry is not very good, I can solder a circuit from a book, but no more", then, obviously, you need to master circuitry. Arduino in robotics is used only in children's circles, study stm32 right away. You also need to know higher mathematics, TAU, electric, hydraulic, pneumatic drive (the most popular is electric), theoretical mechanics. A wide front of tasks is a project manager, and in order to become one, you need not only to know, but to understand everything that I have listed, plus each project needs its own specific knowledge.
There are vacancies in our country. For example, rtc.ru/ru (not advertising). And English is a must.
