Jobs at Djinni

PwC is a global network of more than 370,000 professionals in 149 countries that turns challenges into opportunities. We create innovative solutions in audit, consulting, tax and technology, combining knowledge from all over the world.

Join PwC’s pioneering data & AI team and help build the data foundations behind impactful AI solutions. We’re growing quickly due to a strong pipeline of client work, and we’re hiring across multiple seniority levels — from junior to senior Data Engineers and Data Scientists.

Across our projects, Python is the core skill we expect. Depending on your strengths, you may focus more on data engineering (pipelines, platforms, SQL) or data architecture (designing scalable data solutions). Many roles also include “full-solver” flexibility — contributing where needed, including automation, integration work, or enabling AI/GenAI use cases on modern platforms (including Microsoft technologies where relevant).

Key responsibilities:

• Data Pipeline Design & Development: Design, implement, and maintain scalable data pipelines and ETL/ELT processes, primarily using Python and Spark (PySpark), to ingest, transform, and deliver data from various sources into analytics and ML platforms.
• Data Modelling & Warehousing: Design and optimize data models (e.g. star/snowflake schemas), build and manage data warehouses and data lakes, and ensure data structures support reporting, analytics, and ML use cases.​
• Data Preparation for ML: Collaborate closely with data scientists and ML engineers to understand data requirements, implement robust preprocessing and feature engineering steps, and ensure datasets are clean, consistent, and suitable for machine learning models.
• Performance & Reliability: Optimize data processing jobs and SQL queries for performance and cost efficiency, monitor data pipelines in production, and ensure reliability, scalability, and adherence to SLAs.
• Client Collaboration: Work directly with clients across Western Europe and the USA to understand their data landscape and requirements, translate business needs into technical designs, and provide expert guidance on data architecture and best practices.
• Governance, Quality & Security: Implement data quality checks, validation frameworks, and governance standards; ensure data security, privacy, and compliance in line with PwC and client requirements.
• Learning & Development: Stay at the forefront of data engineering, big data, and cloud technologies, continuously improving existing solutions, tools, and processes.
• Mentorship: Support the growth of junior team members by sharing knowledge, reviewing code, and guiding them in data engineering best practices and project work.

Who We're Looking For:

• Programming Skills (Key Requirement)
  Strong programming skills in Python (e.g. pandas, PySpark, SQLAlchemy, airflow-like tools). Ability to write clean, maintainable, and testable code is essential. Experience with other programming languages is a plus.
• Demonstrated hands-on experience with building data pipelines, ideally using Spark (PySpark) or similar distributed processing frameworks.
• Designing and implementing ETL/ELT workflows.
• Working with large datasets and complex data transformations.
• Database Expertise: Proficiency in SQL databases (designing schemas, writing complex queries, optimization). 
• Cloud & Big Data (Nice to Have / Advantage): Experience with cloud data platforms (preferably Azure: Synapse, Databricks, Data Factory, Azure SQL, Data Lake) or similar services on AWS/GCP.
• Professional Background: At least 2 years of relevant professional experience in data engineering, BI engineering, or similar data-focused roles.
• Analytical Thinking: Strong analytical mindset with the ability to understand complex data landscapes, debug data issues, and design logical, efficient data flows.
• Language Skills: English at B2 level or higher.

We are looking for an Email Compliance Manager to own all communication, ticket management, and compliance coordination with ESPs across a large client portfolio.

You will be responsible for writing, submitting, and managing all interactions with ESP support, compliance, abuse, and deliverability teams. You will act as the strategic communication layer between internal teams and ESPs, ensuring every issue is resolved efficiently and professionally.

You must understand how ESP compliance teams think, how deliverability systems operate, and how to frame communication to achieve optimal outcomes while protecting client accounts.

WHAT WE ARE LOOKING FOR

Must-have

• 3+ years in ESP-side, compliance, deliverability, or direct ESP communications roles
• Strong understanding of ESP compliance systems, abuse handling, and deliverability mechanics
• Exceptional written English (near-native or native level) — writing is your core tool
• Proven ability to manage 30+ clients across different niches simultaneously
• Strong risk identification and problem anticipation skills
• High attention to detail (errors in ESP communication have real consequences)
• Comfortable working flexible hours and across US time zones when required
• Able to operate across all niches without personal or moral restrictions

Nice to have

• Direct experience working inside an ESP (support, compliance, deliverability)
• Familiarity with major ESP internal processes and decision-making systems
• Experience coordinating cross-functional technical or compliance resolutions
• Background in email marketing or marketing operations

WHAT YOU WILL OWN

ESP & Compliance Ticket Management

• Own all ESP ticket submissions and lifecycle management across 30+ clients
• Track, prioritize, and manage all active tickets from open to resolution
• Ensure nothing is lost, delayed, or left without follow-up
• Maintain structured logs of all communications, statuses, and outcomes
• Prioritize tickets based on urgency, compliance risk, and business impact

ESP Communications & Written Strategy

• Write and send all communications to ESP support, compliance, and deliverability teams
• Handle responses to abuse complaints, compliance flags, warnings, and suspensions
• Adapt tone, framing, and strategy based on ESP, issue type, and client context
• Know when to escalate, push back, or concede to protect client accounts
• Ensure all communication is precise, professional, and strategically optimized

Risk & Compliance Management

• Identify deliverability and compliance risks before they escalate
• Understand downstream consequences of every ESP interaction
• Propose mitigation strategies to the Head of Project for high-risk situations
• Stay updated on ESP policy changes, compliance rules, and deliverability trends
• Anticipate issues before they become account-threatening problems

Internal Coordination

• Work closely with email marketers, project managers, and production teams
• Translate ESP requirements into clear internal action items
• Ensure required changes are implemented before responding back to ESPs
• Maintain clear stakeholder communication on all ticket statuses and outcomes
• Follow through until every issue is fully resolved

WHO FITS THIS ROLE

The ideal candidate has worked on the ESP side and understands exactly how compliance and support teams evaluate risk, requests, and sender behavior.

They are a strategic writer who understands that every word sent to an ESP affects outcomes. They can manage a large portfolio of clients without losing track of detail, risk, or urgency.

They are fast, precise, and highly detail-oriented. They think several steps ahead, identifying risks before they become incidents.

They are comfortable working across all niches and understand that this is a behind-the-scenes operational role, not a client-facing or visibility-driven position.

WHO WE ARE

We are a fast-growing operation managing email marketing and deliverability across 30+ clients in multiple niches. We handle all ESP communications and compliance processes on behalf of our clients entirely behind the scenes. The role acts as the final point of contact with email service providers (ESPs), where precision, strategy, and speed directly impact client deliverability and account safety.

This is a high-volume, high-stakes environment. A missed ticket or poorly framed response can result in account restrictions or permanent suspension.

You will report directly to the Head of Project and work closely with internal teams to ensure all ESP issues are resolved end-to-end.

Flexible availability is required. ESP compliance issues do not follow business hours.
