If the job is under Part 135, a SIC is required under IFR, regardless of the whether the aircraft is certificated for more than one crew member. Even if the company is certified for single pilot operations, assuming training program exists for SICs and you meet the 135 requirements, you can log SIC when so designated.
If you are category/rated for the aircraft (airplane, multi engine land), you can log sole manipulator time as PIC. You may not want to do that, however, as there are few employers that will consider your PIC time if you weren't actually PIC.
If Part 91 only, then it doesn't matter if the company designates you as a SIC. If one isn't required by the type certification of the aircraft or the regulations under which the aircraft is operated, then you won't be able to log SIC.
