Onboarding & Activation owns the users journey from first run to paying customer: the onboarding and activation experience that proves the products value and the client-side surfaces that convert it. This spans guided setup trial initiation upgrade paywalls and plan selection and the user-facing subscription plan payment-method and invoice experiences. As the Senior Engineer on this team youll own the back-end logic that sits behind those surfaces: trial state and eligibility activation/onboarding progress tracking and paywall/entitlement gating working in close coordination with the Billing team who own the core subscription payment-provider and licensing systems this teams flows ultimately depend on. This is revenue-critical externally coupled work: a mistake here can let a user through a paywall they shouldnt pass or lock out one who should have access. You will work on a globally distributed asynchronous team that relies on written clarity and a bias to action.

WHAT YOU WILL DO

• Build and maintain the back-end logic for trial initiation and lifecycle (start expiration conversion extension) and the eligibility rules that decide when a user can start or re-start one.
• Build and maintain the entitlement/gating logic behind upgrade paywalls ensuring what a user is shown and permitted to do stays correctly in sync with their actual plan and trial state.
• Design and maintain the back-end services and data model tracking a users onboarding and activation progress in coordination with the client-side guided-setup experience.
• Coordinate closely with the Billing team on the API contract for subscription plan and licensing data this teams flows consume and flag any change that could affect correctness on either side.
• Design clean testable services with explicit success/input-error/conflict/unhandled outcomes avoiding silent failures anywhere a decision affects what a user can access or pay for.
• Author safe backwards-compatible data access and schema changes as this teams own data model (trial state onboarding progress) evolves.
• Uphold the same payment-security and privacy standards as the rest of the org: no raw card data secrets or PII in this teams systems or logs.
• Review pull requests and raise back-end quality; partner with front-end Product and AppSec.

WHAT YOU BRING TO BITWARDEN

• Experience Level: 6-10 years in back-end software engineering with the ability to own services and event/state-transition logic with minimal guidance. C#/.NET ( Core) strongly preferred; strong experience in Java Kotlin Go or a similar statically-typed stack with willingness to ramp is acceptable.
• Correctness and Security Rigor: Experience with correctness-critical state and event handling (e.g. idempotent processing explicit success/error/conflict handling no silent failures) in systems where a mistake affects what a user can access or pay for plus sound judgment around not exposing payment data secrets or PII.
• Relational Data Modeling: Strong SQL skill and the judgment to make safe additive backwards-compatible schema changes.
• Self-Direction and Collaboration: Drives work forward with minimal oversight and collaborates effectively across time zones on a distributed asynchronous team defaulting to written clarity.
• Domain and Integration Experience: Experience with subscription trial or entitlement/feature-gating systems; comfort integrating with or consuming an API contract owned by another team.
• Engineering Practices and Tooling: Feature-flagged rollouts (LaunchDarkly or similar) for staged/gated features; comfort in a large high-traffic monorepo with shared ownership.
