Early career In 1981, Kaiser debuted in the
Second Division with Kamal Sporting Club. In the same year, he represented Dhaka in the U-18 National Junior Football Tournament, after which he was named the tournament's Best Emerging Defender. In 1982, he joined
Rahmatganj MFS in the First Division, playing as a right-back under coach,
Abdur Rahim. He spent the following season at
Team BJMC before returning to Rahmatganj in 1984 after BJMC's relegation from the
First Division. His performance with Rahmatganj in the 1984 season earned him his first call-up to the
Bangladesh national team.
Mohammedan SC Following his international debut, Kaiser joined
Dhaka Mohammedan in 1985. He went on to spend the rest of his career with the Black and Whites, winning the First Division title in 1986, 1987, 1988–89, 1993, 1996, playing as a center-back. He played an ever-present role as Mohammedan were unbeaten in the First Division from 8 September 1985 to 15 March 1990, during which the club won 63 games from the 76 played, and also completed hat-trick league triumphs from 1986 to 1988–89. In 1986, he marshalled Mohammedan's defense alongside
Ranjit Saha, and finished the season with his first league title, playing a crucial role in victories over rivals,
Dhaka Abahani and
Dhaka Wanderers, in the final two games of the Super League round. He began the 1987 season by lifting the
Federation Cup, and in the Super League round of the First Division, Kaiser starred as Mohammedan defeated Abahani 3–2, keeping their domestic double hopes alive, however, with both clubs on equal points, and the return play-off game ending as a stalemate, the players alongside the club officials agreed upon being crowned joint-champions. Nevertheless, the
Bangladesh Football Federation (BFF) opted for a second play-off match at the
Army Stadium, which saw Mohammedan win 2–0. In the same year, Kaiser also represented the club at the
1987 Asian Club Championship, under the coaching of
Nasser Hejazi. Due to his performances at both club and international level, Kaiser eventually received the Sports Writers Association's
Best Footballer Award in 1986 and the
Best Sportsperson Award in 1988. In the 1989–90 season, Kaiser was appointed as club captain by coach Hejazi. Although the club won the Federation Cup under his captaincy, Mohammedan also ended their five-year unbeaten run in the First Division, and finished runners-up to arch-rivals Dhaka Abahani. In the
1989–90 Asian Club Championship, under Kaiser's captaincy, the Black and Whites crashed out of the qualifying group-stages held in
Ahvaz, Iran, finishing runners-up to hosts
Shahin Ahvaz. He remained club captain until the
1991 BTC Club Cup, in which Mohammedan lost the final to Abahani. In the same year, with the First Division not being held in Dhaka, Kaiser represented
Kolkata Mohammedan in the
Calcutta First Division League. He remained a regular member of the team, helping Mohammedan win the league title in both 1993 and 1996. He was also renowned for his goal-scoring abilities, with one of his most notable goals coming during the
DMFA Cup final against Dhaka Abahani in 1993, where he scored from a 30-yard free kick as Mohammedan won 3–2. In 1995, he was an irregular face in the team due to injury problems. He eventually lost his place in the team following the club's appointment of
Kang Man-young, who preferred the younger
Monwar Hossain Munna and
Rajani Kanta Barman at central-defence, and would mainly use Kaiser as a substitute striker during Mohammedan's 1996 league triumph. On 17 December 1996, Kaiser played his final competitive match by coming on as a substitute as Mohammedan defeated Abahani 1–0 at the
Sher-e-Bangla National Stadium in what was the
1996 Premier Division season finale. ==International career==
