Casual: He's the second from the top at my company.
Business: He's the second most senior person at my company.
いろんな言い方はありますが、友達にカジュアルに言うなら①He's the second from the top at my company.
もう少し、かしこまった感じでいうならば②He's the second most senior person at my company.
ちなみに、私の母国のアメリカでは、上下関係は日本見たいにありません。
例えば、仕事が終わったら、帰ります。自分より偉い方が帰るまで待つ習慣はありません。
会議では下のランクの方は自由に意見をのべるのも一般的です。逆に下の人が手を上げて積極的に自分の意見を言うのが上に上がるチャンスと思って、積極的に偉い人にも提案したりしています。
異文化の例も入れましたけれども、英語と同時に少しでも仕事場の異文化比較もできたら嬉しいですね。
英語頑張って下さい！応援しています。ジャニカ
社内で他のメンバーに紹介する時は：① He is the vice president.
シンプルに。副社長です。
もし副社長でなく、別のポジションで二番目に偉い人ならば：
He's the second most senior person here. ＝ 意訳：（ここでは２番目に偉い人）を使いましょう。
追伸：誰に話しているかによって英語が微妙に異なってくるので、社内ではhere, our, us, this, weなどを使い、社外の人物に話す時はmy, ourに限定されます。

As in politics the 2nd in command in a company, is refered to as the Vice President.
He is almost at the top of the company...Just one more step to go;-D
The Vice president" is to all intents and purposes "the number 2" in a corporate structure scenario...
彼はもう少しで会社のトップですが、だたもう一歩です;-D
"The Vice president"(副社長）とは企業での"the number 2"（ナンバー2）と言う事を意味します。
'Chief Officer' is a naval term applied to the first officer, who is deputy to the Captain. He is someone who would replace the Captain if necessary. He is second in command, so this naval analogy could be applied but may require explanation. Being second in anything is not usually something anyone wants to advertise! Best to use his established job title and maybe explain later about him being second in command? A title such as SENIOR DIRECTOR, VICE C.E.O, SENIOR PARTNER, SENIOR EXECUTIVE, for example.
He or she works directly under (name of the top person).
The top person in a company is called the President, so the person can be called a "Vice President"
Second in command means they are bellow the top person.
"works directly under" means works bellow the top person and is next in charge.
"企業のトップはthe Presidentと呼ばれ、企業のNO2は""Vice President""
と呼ばれます。
Second in commandはトップの次のポジションの人という意味です。
works directly under""はトップの人の下で働いていてNo2だという意味です。"
This means that they come after the President in terms of hierarchy.
Hierarchy means a system in which members of an organization or society are ranked according to relative status or authority.
There are various ways in which you may refer to a person who is the number 2 of a company. Generally, you may refer to him/her as the 'Second in Command' or 'Second in Charge'. However, if you want to use titles, in countries such as the UK and South Africa, the top person in a company is referred to as the Chief Executive Officer (CEO), and, his second in command is referred to as the 'Deputy CEO'. In the USA, the top man in the company is known as the 'President', and, his/her second in command is referred to as the 'Vice President'.
So, you may say:
This is (name), our Deputy CEO. (UK/South Africa)
or
Our Deputy CEO will be chairing the meeting.
or
This is (name), our company's Vice President. (USA)
or
Our company's Vice President will be chairing the meeting.
会社のナンバー2を表す言い方はいろいろあります。「Second in Command」や「Second in Charge」が一般的です。『肩書』ということなら、イギリスや南アフリカなどでは、会社のトップは「Chief Executive Officer (CEO)」、ナンバー2は「Deputy CEO」、アメリカでは、トップが「President」、ナンバー2は「Vice President」と呼ばれます。
例：
This is (name), our Deputy CEO. (イギリス／南アフリカ)
〈こちらは副CEOの(name)です〉
Our Deputy CEO will be chairing the meeting.
〈私たちの会社の副CEOが議長を務めます〉
This is (name), our company's Vice President. (アメリカ)
〈こちら副社長の(name)です〉
Our company's Vice President will be chairing the meeting.
〈私たちの会社の副社長が議長を務めます〉
