About the right team member

You love to design robust and easy to use APIs and services taking ownership of technical decisions. You’re capable of leading complex technical projects with high levels of uncertainty, scale, and interdependencies—creating timelines, delegating tasks, and ensuring smooth launches. You learn quickly and ramp up on new systems, languages, or frameworks with minimal guidance. You’re not afraid to ask questions early and often in unfamiliar territory. You are a sought-after contributor in code reviews, helping elevate code quality through timely and constructive feedback. You are an expert in one or more technical areas and are recognized within your team as a trusted source of insights and mentorship.

At Playlist we value people who are intellectually curious, who are pragmatic not dogmatic, and people who care about our product, their teammates, and their own personal growth. We are faced with an interesting set of technical challenges, and we believe in giving our engineers the autonomy to go and solve them. Much of our team comes from non-traditional computing backgrounds; we know that by bringing together a diverse set of voices we’ll be able to build a better product, and a better company. We care less about what languages or frameworks you know, and care more that you are excited to produce high-quality code and be constantly learning. Our engineers work in cross-functional teams that are focused on impact, and movement between teams is encouraged. We work very closely with our brilliant product team to deliver a world class user experience, and ultimately to empower our users to live their fullest, healthiest lives.

You’ll thrive in this role with experience in

• 8+ years' experience in programming large-scale SaaS products.

• Experience building backend services with an object-oriented language such as C# or Java.

• Experience designing and architecting backend services.

• Experience Designing and working with Microservice architecture.

• Experience with monitoring systems such as New Relic or Kibana.

• Familiarity with SDLC and programming design patterns, and Agile methodology.

• Experience reviewing new feature impact on an application and recognizing potential risks.

• Detail-oriented, professional and possesses a positive work attitude.

• Ability to communicate professionally both verbally and in writing.

Nice to have

• Experience building or operating payment flows end to end — authorization, capture, settlement, refunds, and reconciliation.

• Hands-on integration with a payment gateway or PSP, including webhook-driven state handling.

• Experience making payment operations safe to retry — idempotency, retries, and eventual consistency — so a request that fails partway through doesn't double-charge a customer.

• Working knowledge of PCI DSS scope, tokenization, and handling sensitive payment data safely.

Technologies you’ll be working with

~ You don’t need experience with every item below—what matters is strong fundamentals and the ability to learn quickly ~

• Experience building high-performing, high-quality backend systems. Our codebase is diverse and includes .NET, C#, Java, JavaScript, Kotlin, Python, React, and Ruby, but we’re less focused on experience with a specific language and more interested in your ability to build reliable, well-designed systems.

• Data: PostgreSQL/MongoDB/DynamoDB, Redis, schema migrations, indexing, partitioning/sharding

• Strong understanding of SQL and relational databases.

• AWS Cloud

• AI tooling: Claude Code/ Cursor/ Codex-style coding assistants; MCPs; agent/orchestration frameworks; safety harnesses

• Engineering Practices: automated testing, code reviews, CI/CD, observability, on-call, incident management — with AI-accelerated workflows where appropriate
