ABOUT CENTRAX DIGITAL
Centrax Digital is an AI-first consulting and digital engineering firm operating from Bryanston, Sandton and Grand Prairie, Texas. We are a Level 1 B-BBEE, black woman-owned Advanced Zoho Partner. Our work spans AI and advisory, platforms, cloud and security, and digital engineering, delivered on our own published methodology. Because Innovation Matters.
THE ROLE
To convert qualified opportunities into commercially defensible proposals. You are accountable for the quality of effort estimation, the rigour of opportunity qualification, and the writability of the proposal documents.
WHAT YOU WILL DO
- Run discovery sessions with prospects alongside the Account Executive.
- Apply qualification methodology such as MEDDIC and document the opportunity scoring.
- Estimate effort across practices using the Centrax estimator tooling and the relevant practice libraries.
- Score opportunity complexity using the Centrax complexity rubric and flag deals outside the standard risk envelope.
- Write proposal documents covering executive summary, solution approach, scope, deliverables, assumptions, and commercials.
- Coordinate input from practice leads and Solution Architects into the proposal.
- Coach Account Executives on opportunity progression, qualification gaps, and commercial structuring.
- Maintain the proposal library and reusable scope clauses.
- Support negotiation by translating client pushback into commercial alternatives, and contribute to win-loss reviews.
WHAT YOU NEED
- Bachelor's degree in Business, Information Systems, Engineering, or a related field.
- Minimum 5 years' experience in consulting, professional services, or technology delivery, with at least 2 years in a pre-sales or solution scoping role.
- Experience writing client-facing proposals at executive level.
- Experience working across multiple technical practices in a single proposal.
- Experience with consulting estimator tools and effort calibration.
- Comfortable with margin modelling, rate-cost analysis, and sensitivity testing in Excel or Zoho Sheet.
- Sales methodology certification such as MEDDIC, SPIN, or Challenger preferred. Project management certification is an advantage.
WHERE THE BOUNDARIES SIT
Deal ownership and negotiation sit with the Account Executive. Architecture sign-off sits with the Solution Architect.
HOW THIS ROLE EVOLVES
Centrax is concurrently advertising a Solutions and Pre-Sales Lead (JH01), a composite role that holds architecture authority and major pursuit pre-sales in one seat until dedicated appointments are made. Candidates for this position may also be considered for that one.
WORKING ARRANGEMENTS
Standard working hours of 08:00 to 17:00, Monday to Friday, with flexibility around proposal deadlines and major pursuits. Hybrid working in line with company policy. Occasional travel for client discovery and pitch presentations. Standard 21 days annual leave and BCEA leave entitlements apply.
REMUNERATION
Market related, commensurate with experience.
