Senior Software Engineer - Boston

• Shape the bigger picture. You won’t just build features, you’ll refine the what to build and why. At Perk, senior engineers are expected to go beyond the technical solution and focus on the problem itself. You’ll contribute to your squad’s quarterly goals and long-term vision alongside your Product Manager and Engineering Manager.
• Architect for today and tomorrow. When a big change is needed in how our platform works, you’ll be the one writing the design documents that lay the foundation. You’ll become a guardian of your team’s technical quality; spotting areas of investment, proactively managing technical debt, and making sure we don’t let “busy work” crowd out the work that truly matters. At Perk, we believe in impact over effort: our customers see results, not the hours behind them. Your job is to make sure we’re always investing our energy where it counts most.
• Lead across boundaries. Your influence won’t stop at your own squad. You’ll communicate complex ideas across multiple teams, proactively identify who needs to be involved, and drive alignment across the broader organisation. Whether it’s coordinating a cross-squad initiative, contributing to one of our engineering guilds (where engineers from different teams align on shared technical topics), or pairing with architects on solution discovery, you’ll operate comfortably beyond your immediate team.
• Raise the bar for everyone around you. Senior engineers at Perk are mentors, coaches, and bar raisers. You’ll support less experienced colleagues through direct mentorship, thoughtful feedback during reviews, and by modelling what great engineering looks like in practice. You’ll help Engineering Managers understand where the team needs to grow technically, and you’ll use spaces like guild meetings, design doc reviews, and pairing sessions to lift the overall standard. At Perk, we are a team, the team’s success is your success., * Product Leadership: Translates complex business goals into technical roadmaps; de-risks ambiguous projects through spikes and prototyping.
• System Architecture: Architects scalable, evolvable systems and data models that account for performance, failure isolation, and long-term maintenance.
• Technical Standards: Defines and upholds engineering excellence, including CI/CD optimizations, testing strategies, and coding standards across the stack.
• Frontend Strategy: Establishes frontend architecture patterns, including state management, performance budgets, and comprehensive testing (e.g., E2E/Cypress).
• Backend Excellence: Engineers sophisticated backend solutions involving API versioning, caching strategies, and complex data migration plans.
• Operational Maturity: Leads observability and SRE practices; defines SLOs, manages incident responses, and conducts blameless post-mortems.
• Security & Risk: Oversees operational security, including secrets hygiene and dependency risk management, to ensure a hardened production environment.
• Mentorship & Influence: Levels up the engineering organization through active mentorship, leading design reviews, and influencing the product roadmap with technical data.
• Cross-Functional Impact: Coordinates multi-team deliverables and aligns stakeholders to resolve technical blockers across the organization.

AI at Perk:

• AI is embedded in how we work and what we build. It spans the whole workflow: our Notion, Jira, GitHub and Slack are AI-connected so you get up to speed fast, and day-to-day it helps with specifying features, writing and reviewing code, and automated AI PR review on every pull request. When something goes wrong in production, AI surfaces context across systems quickly. We also embrace agentic coding, using AI as an active collaborator, not just a prompt-by-prompt co-pilot.
• We expect candidates to use AI tools in our coding interviews. The bar is understanding your code and owning what you produce. That reflects how we work every day.
