Senior Manager, Software Engineer
- Greece-Thessaloniki Chortiatis
ROLE SUMMARY
As Senior Manager, Software Engineer (Individual Contributor), you will be a senior technical authority within the Enterprise AI Capability Design Team, responsible for designing and implementing modular, reusable AI capabilities in the form of SDKs and associated components. Your mission is to build developer-first, extensible SDKs that enable internal teams and the broader community to integrate AI capabilities seamlessly into applications, while maintaining consistency, quality, and performance.
You will design and implement core modules for RAG pipelines, agent and tool cookiecutters, MCP adaptors, and standardized interfaces that allow community-driven extensions. You will also collaborate on automated pipelines for code quality checks, benchmarking, and integration tests, ensuring every capability meets enterprise-grade standards for reliability, security, and observability.
This role requires close collaboration with:
Embedded AI Architecture Team and Solution Design Team to prioritize capabilities and define SDK interfaces aligned to real-world solution patterns.
AI Engineering Team, which actively develops PI increments of the SDK and integrates external technologies.
Digital Creation Centers and Forward Impact Teams (FITs), who will consume these capabilities in product delivery and provide feedback for continuous improvement.
Why this Role Matters
This role is the engineering backbone of our AI capability strategy. By delivering high-quality SDKs and reusable modules, you enable rapid adoption, reduce bespoke engineering, and ensure parity between SDK and service implementations. Your work directly impacts developer experience, scalability, and the ability to operationalize AI capabilities across the enterprise.
ROLE RESPONSIBILITIES
1) SDK & Module Development
Design and implement modular SDK components for AI capabilities, including:
RAG pipeline modules (parsers, chunkers, enrichers, retrievers, rankers, connectors)
Cookiecutters for agents and tools with MCP adaptors
Standardized interfaces for community-driven extensions
Ensure SDKs are extensible, composable, and versioned with clear upgrade paths.
2) Collaboration & Interface Definition
Work closely with Embedded AI Architects and Solution Designers to define SDK interfaces and design patterns based on prioritized use cases.
Partner with AI Engineering Team to integrate external technologies, validate new components, and align on PI increments for SDK evolution.
Engage with Digital Creation Centers and FITs to capture feedback on usability, performance, and integration experience.
3) Code Quality & Testing Automation
Collaborate with Evaluation & QA Engineers to integrate unit, integration, and performance tests into CI/CD pipelines.
Implement automated code quality checks, linting, and security scans for SDK components.
Contribute to benchmarking frameworks for new modules and features.
4) Developer Experience & Enablement
Work closely with Developer Experience Engineers to deliver clear APIs, ergonomic SDK design, and developer-friendly documentation.
Provide quickstarts, code samples, and integration guides to accelerate adoption.
Participate in community enablement efforts, ensuring SDK interfaces are intuitive and extensible.
5) Architecture & Standards Alignment
Align SDK design with enterprise architecture principles, ensuring parity with service implementations.
Collaborate with AI Capability Architecture Lead on interface contracts, observability hooks, and security-by-design patterns.
Maintain semantic versioning and backward compatibility policies for SDK releases.
MEASURES OF SUCCESS
SDK quality and adoption: High developer satisfaction; increased reuse across products; minimal bespoke implementations.
Release health: Predictable release cadence; automated quality gates; successful integration tests.
Performance and reliability: SDK modules meet latency, throughput, and cost targets; observability hooks implemented.
Community engagement: Positive feedback on extensibility and contribution workflows; active feature branch participation.
Documentation completeness: Clear quickstarts, code samples, and integration guides delivered with each release.
QUALIFICATIONS
Basic Qualifications
7+ years in software engineering roles with strong experience in API/SDK design and modular architecture.
Proficiency in modern programming languages (Python required).
Hands-on experience with cloud-native development (Azure, AWS, or GCP) and containerized environments.
Strong understanding of CI/CD pipelines, automated testing, and code quality practices.
Ability to produce developer-friendly SDKs with clear documentation and ergonomic interfaces.
Proficiency in Git-based workflows (feature branches, PR reviews, semantic versioning)
Preferred Qualifications
Experience with AI/ML frameworks (PyTorch, TensorFlow) and GenAI/LLM ecosystems (prompt tooling, RAG, vector databases, agent frameworks).
Contribution to open-source projects and/or community-driven extensions.
Exposure to observability tooling (metrics, tracing, logging) and security-by-design principles.
Background in performance engineering and benchmarking for AI workloads.
Experience in regulated environments with audit-ready documentation and compliance standards.

Breakthroughs that change patients’ lives
Research confirms what intuition tells us: that purpose-driven companies perform better, are more innovative, attract and retain the best people, and know how to unleash the power of those people. Pfizer’s purpose—Breakthroughs that change patients' lives—fuels everything we do and reflects our passion for building on our legacy as one of the greatest contributors of good to the world.
Each word in our purpose has meaning and reflects the value we strive to bring to patients and society:
“Breakthroughs” - These are the innovations, scientific and commercial, that we seek to deliver every day. All colleagues, regardless of role, level or location, strive for breakthroughs every day.
“Change” - We want to do more than simply improve patients’ medical conditions; we want to dramatically change their lives for the better.
“Patients’ lives” - We consider not only patients, but everyone they touch—including their families, caregivers, and friends—and everything they love to do. It’s an intentionally holistic view.
Our purpose ensures that patients remain at the center of all we do. We live our purpose by sourcing the best science in the world; partnering with others in the healthcare system to improve access to our medicines; using digital technologies to enhance our drug discovery and development, as well as patient outcomes; and leading the conversation to advocate for pro-innovation/pro-patient policies.
Every decision we make and every action we take is done with the patient in mind—and to nurture an environment where breakthroughs can thrive.
Our Values
To fully realize Pfizer’s purpose, we have established a clear set of expectations regarding “what” we need to achieve for patients and “how” we will go about achieving those goals.
The “how” is represented by four simple, powerful values—courage, excellence, equity, and joy—that define our company and our culture.
Courage: Breakthroughs start by challenging convention, especially in the face of uncertainty or adversity. This happens when we think big, speak up, and are decisive.
Excellence: We can only change patients’ lives when we perform at our best together. This happens when we focus on what matters, agree who does what, and measure our outcomes.
Equity: We believe that every person deserves to be seen, heard, and cared for. This happens when we are inclusive, act with integrity, and reduce healthcare disparities.
Joy: We give ourselves to our work, but it also gives to us. We find joy when we take pride, recognize one another, and have fun.
Pfizer Digital
Pfizer Digital takes immense pride in being at the forefront of innovation, harnessing cutting-edge smart technology that profoundly impacts the lives of our patients.
With the transformative potential of digital solutions, we revolutionize how we discover, develop, and deliver medicines, enabling us to achieve breakthroughs faster and more efficiently.
