K sh 170,000 – 260,000 gross / month

Openings: 1 Location: Nairobi – Koma Rock (Eastern bypass industrial pocket) Overview: This Materials Engineer role is built for someone who thrives where precision meets pressure. You’ll be the guardian of concrete and asphalt quality across multiple active sites mixes, temperatures, moisture, gradation, all the invisible details that decide whether a pavement lasts twenty years or five. Your day swings between lab benches, batching plants, and live pours where decisions need to be crisp and data-backed. On the concrete side, you’ll design mixes, supervise trial batches, and run cube tests that keep strength, workability, and cost in balance. Asphalt brings its own rhythm: density checks, bitumen content verification, and keeping plant QC tight enough that a single bad truck doesn’t compromise an entire stretch of road. Documentation must stay sharp temperature logs, calibration records, sampling chains, and test sheets that auditors won’t challenge. You’ll also act as the trouble-shooter when things go sideways: early cracks, segregation, compaction issues, or failed tests. Investigations need to be calm, methodical, and grounded in standards (ASTM/BS), followed by fixes that the client and contractors can actually implement on the next shift. Your success is measured not just in pass rates but in how little rework, waste, and dispute you allow onto the project. Candidates with 4–6 years in concrete/asphalt QC, plus a solid grip on lab methods, SPC, and specs, will fit well. The growth path is clear and technical: Senior Materials Engineer → QA/QC Manager → Technical Director (Materials). Key Responsibilities: - Design/validate mixes; run trials and cube tests. - Oversee batching, delivery, temperature logs, and slump control. - Manage asphalt plant QC; density, gradation, bitumen content. - Coordinate labs; ensure equipment calibration and traceability. - Investigate failures; propose fixes and specs updates. Education & Experience: - BSc Civil/Materials Eng; 4–6 yrs concrete/asphalt QA/QC. Skills & Tools: - Lab methods, statistics/SPC, specs (ASTM/BS), site coordination. KPIs: - Test pass rate, NCRs closed, waste/rework %, supplier quality. Compensation (Kenya): KES 170,000–260,000 + project bonus. Client estimates vary with portfolio & accreditation. Benefits Medical, PPE, per diems, training. Growth Path Senior Materials Eng → QA/QC Manager → Technical Director (Materials). Ideal promotion cycle.
