Abdul Mu'iz bin Sisa (born 20 April 1991) is a professional footballer from Brunei who occupies the left full-back position for Kasuka FC in the Brunei Super League. He achieved two Brunei Super League championships early in his career with Indera SC during the 2012–13 and 2014 seasons, and later added the Singapore Premier League title to his accolades with DPMM FC in 2019.

Indera

Rising through the ranks of Indera SC's youth academy, Abdul Mu'iz established himself as a consistent left-back starting from the 2007-08 campaign. During his tenure, he contributed to securing two league titles along with one Piala Sumbangsih triumph.

DPMM

In 2016, Abdul Mu'iz signed with Brunei's only professional football outfit, DPMM FC, stepping in after Sairol Sahari sustained a season-ending injury that left the team in need of a local left-back. Having already earned recognition as a Brunei international, he joined the club following a successful trial in June of that year.

He made his first appearance on 26 September 2016 during a high-scoring 5–3 victory over Young Lions, primarily serving as a secondary option behind Najib Tarif. On 4 December 2022, Abdul Mu'iz featured in the final of the 2022 Brunei FA Cup, collecting his inaugural FA Cup winner’s accolade as DPMM edged out Kasuka FC 2–1, despite being substituted due to injury. After dedicating nine years to this royal-backed club, he was released after the conclusion of the 2024–25 season.

Youth

Abdul Mu'iz's international journey commenced with the under-21 side. Although he did not play at the 2007 Hassanal Bolkiah Trophy, he played a key role in Brunei’s victorious campaign at the same tournament in 2012, which was hosted on home ground.

He advanced to represent the under-23 squad at the 27th SEA Games held in Myanmar, where Brunei ended at the bottom of their group after suffering defeats in all matches.

Senior

In March 2015, Abdul Mu'iz was selected for Brunei’s senior squad during the AFC first round qualifiers for the 2018 World Cup against Chinese Taipei. He started both legs, though Brunei was eliminated with a 1-2 aggregate scoreline. Later that year, he participated in friendly matches against Singapore and Cambodia, notably scoring a memorable chipped goal versus Singapore.

In September 2018, he was called up for the 2018 AFF Suzuki Cup qualification fixtures against Timor-Leste. He entered as a substitute during the first leg (a 3–1 loss) and started at left-back for the second leg, which Brunei won 1–0; however, this was insufficient for progression.

Abdul Mu'iz declined a recall by coach Robbie Servais for the 2022 World Cup qualifiers in June 2019 due to undisclosed reasons.

He returned to international duty for the 2022 AFF Mitsubishi Electric Cup qualifiers against Timor-Leste, starting in the second leg that ended in a narrow 1–0 defeat but allowed Brunei to advance on a 6–3 aggregate. Throughout the tournament proper, he featured twice as Brunei suffered heavy 5–1 losses to both the Philippines and Cambodia.

On 11 September 2023, he started in an overwhelming 10–0 loss to Hong Kong. Subsequently, he was selected for Brunei’s squad in the first round of AFC qualifiers for the 2026 World Cup against Indonesia, starting in a crushing 6–0 defeat. The team was eliminated following a comprehensive 0–12 aggregate loss.

In September 2024, Abdul Mu'iz was named in Brunei’s lineup for their play-off round in qualification for the 2027 AFC Asian Cup against Macau. He started both matches and played an integral role as Brunei secured a convincing 4–0 aggregate win. The following month saw him make two substitute appearances during qualification for the 2024 ASEAN Championship; however, Brunei was narrowly eliminated on a 0–1 aggregate scoreline. In November, he featured in an international friendly where Brunei suffered an emphatic 11–0 defeat to Russia.

Following a one-year suspension linked to disciplinary issues within the national team during 2024, Abdul Mu'iz made his comeback on 18 November 2025 as a substitute during Brunei’s home fixture against Lebanon in the 2027 Asian Cup qualifiers, which ended in a 0–3 loss.
