Contact Centre Engineer

We are looking for an experienced Senior Contact Center Solutions & Implementation Engineer to independently lead the technical delivery of an enterprise contact-center implementation and integration engagement.

This is a hands-on contract opportunity for a senior engineer who is comfortable taking ownership of a project from technical discovery and solution architecture through configuration, integration, testing, deployment, stabilization, and handoff.

The ideal candidate combines strong software and systems engineering skills with practical experience in contact-center technologies, voice/telephony environments, enterprise integrations, APIs, CRM systems, databases, and cloud-based solutions.

This is not a narrowly scoped development assignment. We are looking for someone capable of understanding business requirements, making sound architectural decisions, solving technical problems independently, and driving the implementation to successful completion.

Key Responsibilities

Take end-to-end technical ownership of contact-center solution implementation and deployment.

Participate in technical discovery and translate business requirements into scalable technical solutions.

Design solution architecture covering contact-center applications, voice/telephony services, CRM platforms, databases, APIs, analytics, and other integrated systems.

Configure and customize contact-center solutions based on functional requirements and implementation best practices.

Design, build, test, and troubleshoot integrations between enterprise applications.

Develop and consume REST APIs, web services, webhooks, and other integration interfaces.

Perform data mapping, transformation, synchronization, and migration where required.

Design and optimize relational database structures, queries, and supporting data workflows.

Troubleshoot complex issues involving applications, APIs, databases, networked services, configuration, and system integrations.

Coordinate technical dependencies between multiple applications and services.

Create technical implementation, testing, deployment, and rollback plans.

Support system integration testing and user acceptance testing.

Diagnose and resolve defects identified during implementation and testing.

Lead production deployment and post-deployment stabilization activities.

Communicate implementation progress, risks, blockers, and technical recommendations clearly to stakeholders.

Maintain accurate technical and operational documentation.

Provide knowledge transfer and a structured technical handoff at the completion of the engagement.

Provide technical guidance to other engineers when required.

Consulting & Project Delivery Skills

Because this is a customer-facing technical engagement, the successful contractor must also be comfortable with:

Technical discovery sessions

Requirements gathering

Business and technical analysis

Stakeholder communication

Technical presentations

Project planning

Risk and dependency identification

Issue management

Implementation status reporting

Managing technical expectations

Working with both technical and non-technical stakeholders

You should be able to work with limited supervision and proactively identify what needs to be done to keep the implementation moving forward.

Expected Deliverables

The contractor will be expected to produce and/or maintain deliverables including:

Technical requirements documentation

Solution architecture

Integration architecture and data-flow documentation

System configuration

API and external-system integrations

Database queries, schemas, and mappings where required

The engagement will be considered successful when the delivered solution:

Meets agreed functional and technical requirements.

Operates reliably in the target production environment.

Successfully integrates with required enterprise systems.

Has completed the required technical and business testing.

Has major defects and integration issues resolved.

Includes clear documentation for ongoing support and maintenance.

Engagement Structure

Type: Freelance / Independent Contractor

The contractor is expected to operate with a high degree of independence and take meaningful ownership of technical delivery.

Rather than simply receiving individual development tickets, the selected engineer should be able to:

Understand requirements → design the solution → configure/build integrations → test → troubleshoot → deploy → stabilize → document → hand off.
