Product Delivery & Execution

• Own the development from Softwar Engineering of end‑to‑end product capabilities for Nova, from backend integration through to user‑facing experiences.
• Partner with the UX/Product and engineering leadership to refine requirements, shape scope, define delivery sequencing with clear trade‑offs, iterate quickly using prototypes, feedback loops, and measurable outcomes
• Provide accurate estimates, identify dependencies early, and proactively manage risks to keep delivery predictable.
• Balance near‑term feature delivery with longer‑term maintainability by proposing and implementing pragmatic architectural improvements.

Full‑Stack Development (Backend + Frontend)

• Design and implement robust backend services, APIs, and integrations with enterprise systems and platform services (identity, events, APIs, data access)..
• Build workflow-driven experiences (actions, recommendations, tasks) beyond dashboards.
• Build high-quality frontend applications with strong attention to usability, performance, accessibility, and developer experience.
• Define and enforce API contracts, data models, and integration patterns to ensure reliable cross‑component collaboration.

Technical Leadership (as a Senior IC)

• Serve as a technical anchor for the squad: influence design decisions, align implementation with architecture standards, and mentor others through reviews and pairing.
• Raise the technical bar through strong engineering judgement, clear recommendations, and a bias for simple, resilient solutions.
• Collaborate closely with Solutions/Data Architects to ensure the product aligns with broader PepsiCo capabilities and integration standards.

Engineering Excellence & Quality

• Set a high standard for code quality: clean architecture, maintainable structure, consistent patterns, and strong test coverage.
• Establish and improve automated testing strategies.
• Contribute to CI/CD pipelines, observability (logging/metrics/tracing), and reliable release practices (progressive rollouts, rollback plans).
• Proactively identify and reduce technical debt, addressing root causes and preventing recurring issues.
• Build for scalability and performance, including profiling, optimisation, and capacity-minded design.

Collaboration & Stakeholder Engagement

• Work effectively across disciplines (data engineering, BI engineering, data science) to deliver integrated solutions end‑to‑end.
• Communicate clearly with stakeholders: explain technical constraints, propose options, and support demos and feedback loops.
• Coordinate with US DTX product/engineering counterparts when beneficial, sharing knowledge and aligning on reusable patterns while respecting independent operating models.

• Stay current with relevant full‑stack and platform technologies, and bring pragmatic innovation to the product.

• 5+ years of experience in software engineering
• Background collaborating with data engineers, BI engineers, data scientists, and product managers in data‑driven products.
• Strong software engineering foundation and able to evaluate architecture, review code, and guide technical decisions across frontend and backend
• Experience with Elixir is mandatory. Experience with comparable functional programming languages (e.g. Scala, Erlang, Clojure), or strong willingness to learn, is a plus.
• Familiarity with modern data stack (Snowflake, dbt, Airflow, Azure, AWS, etc)
• Understanding of BI tools and their limitations, as well as exposure to data science and ML integrations within products
• Experience establishing or significantly improving engineering best practices in a growing or maturing environment
• Exposure to data science or ML‑enabled features within products, including consuming models via APIs or production pipelines.
• Experience applying and contributing to engineering best practices such as clean architecture, testing, CI/CD, documentation, and code reviews
• Comfortable with ambiguity and evolving scope
• Strong prioritization skills balancing long-term scalability with short-term delivery needs
