Senior Back End Engineer
PrizePicks
Role Description We are seeking an experienced Senior Software Engineer with deep expertise in Ruby on Rails to join our Checkout & Gameplay team. In this role, you will design, build, and own critical Rails-based backend services that power PrizePicks’ core platform, including our checkout, game types, and validation services. You will tackle high-scope, complex technical problems, define the technical path from product idea to production, and mentor engineers across your team and the organization. This is a role for someone who thrives on solving hard backend problems and wants to have a direct impact on a product used by millions. What You’ll Do - Design and build backend services: Architect and implement Rails-based services that are performant, scalable, and reliable, supporting high-throughput workloads and complex business logic. - Own technical delivery: Lead the technical design and implementation of complex features end-to-end — from product requirements through deployment and monitoring. - Drive system reliability: Diagnose and resolve performance bottlenecks, optimize database queries, and improve the resilience of backend systems under load. - Define technical direction: Propose and drive architectural decisions for your team’s services, evaluating tradeoffs and communicating recommendations clearly. - Mentor and elevate: Provide hands-on mentorship to Software Engineers I, II, and III on your team and in the organization through code reviews, pairing, and technical guidance. - Improve engineering practices: Define, advocate for, and improve best practices around code quality, testing, observability, and deployment for your team. - Collaborate cross-functionally: Work closely with Product Managers, Designers, QA, and other engineering teams to translate product goals into well-scoped technical solutions. - Participate in on-call rotation: Share responsibility for production incidents, contributing to root cause analysis and long-term reliability improvements. Qualifications - 5–8 years of professional software engineering experience, with significant time building production Ruby on Rails applications. - Proven track record of owning and delivering complex, multi-component features in a team environment. - Experience designing and operating backend systems that handle significant scale and complexity. Requirements - Expert-level Ruby on Rails proficiency — you understand the framework deeply, write idiomatic Ruby, and know when to leverage or work around Rails conventions. - Strong proficiency with PostgreSQL, including schema design, query optimization, and performance tuning at scale. - Solid understanding of API design — RESTful services, serialization strategies, and versioning. - Experience with background job processing (Sidekiq or similar) and asynchronous workflows. - Experience with containerization (Docker) and orchestration (Kubernetes). - Familiarity with CI/CD pipelines and deployment automation. - Understanding of observability practices — logging, metrics, tracing. - Working knowledge of Go — our backend includes significant Go services, and cross-stack capability is valued at this level. Working Style - Comfortable working autonomously with minimal direction on ambiguous problems. - Effective communicator who can articulate technical decisions to both engineers and non-technical stakeholders. - Experience working in a fully remote engineering organization. - Able to context-switch between deep technical work and collaborative planning. What Makes You Stand Out - Experience leveraging AI-assisted development tools across the development lifecycle — coding, planning, scoping, and code review. - Experience integrating AI tooling into engineering workflows to accelerate team productivity. Benefits - Company-subsidized medical, dental, & vision plans. - 401(k) plan with company match. - Annual bonus. - Flexible PTO to encourage a healthy work/life balance (2 weeks STRONGLY encouraged!). - Generous paid leave programs, including 16-week paid parental leave and disability benefits. - Workplace flexibility and modern work schedules focused on getting the job done, not hours clocked. - Company-wide in-person events and team outings. - Lifestyle enhancement program. - Company equipment provided (Windows & Mac options). - Annual performance reviews with opportunities for growth and career development.

Job Description The Director of Journey Orchestration Operations turns Integrated Marketing campaigns into executable, scalable orchestration activations across the marketing technology stack.  This role owns journey architecture patterns, reusable templates, and the trigger and suppression standards that prevent channel conflicts and audience overlap across buying group members.  - Sits at the intersection of strategy and execution, translating stage definitions and journey intent into dependable, repeatable orchestration patterns used across Education, Acquisition, and Progression campaign types.  - Partners with Integrated Marketing, Marketing Automation, Identity/CDP, DX, and Measurement to activate reliable signals, align lifecycle programs, and improve buying group progression outcomes across owned and paid channels.  Responsibilities  - Convert Integrated's stage definitions and journey intent into executable configurations and reusable templates across lifecycle platforms, including entry criteria, trigger logic, suppression, prioritization, exits, and measurement hooks.   - Build and maintain a library of modular templates and standard decision patterns across buying group role profiles (Champions, Decision Makers, and Influencers) to reduce reinvention and speed deployment.   - Partner with media teams on how journey strategy translates into buy-side activation platforms in social, programmatic, and SEM.  - Define trigger and suppression standards to prevent channel conflicts, duplicate outreach, and segmentation collisions across buying group members, including frequency and eligibility guardrails when multiple programs compete for the same audience.   - Align orchestration logic with Marketo/AJO program structure and lifecycle rules, including suppression coordination across tools and channels.   - Partner with DX to ensure site behaviors, landing page events, and variant instrumentation meet minimum standards for event taxonomy, latency, completeness, and governance needed as journey signals.   - Define integration requirements across the orchestration stack: audience entry and membership logic (CDP/CRM), event ingestion and behavioral signals, suppression and frequency coordination, and measurement hooks tied to stage progression.   - Partner with Identity/CDP teams on audience availability, refresh cadence, and event signal mapping needed for orchestration decisions.   - Provide journey performance insights and recommended iterations to Integrated and Media teams:  drop-offs, stage friction, signal gaps, sequencing issues.   - Partner with Measurement to align progression metrics, scoring outputs, and reporting views to the journey logic.   - Set governance for template adoption, exception handling, and change management, reducing manual orchestration through increased reuse and standardized decision patterns.
