[Remote] Sr. Backend Engineer

Remote · Nigeria Full-time

Note: The job is a remote job and is open to candidates in USA. Clinical Ink is the global life science company that brings data, technology, and patient science together to unlock clinical discovery. They are seeking a Senior Backend Engineer to own a service or domain end-to-end, focusing on design, implementation, and reliability of backend services while mentoring less-senior engineers.

Responsibilities

  • Design and build backend services in our Python stack: APIs, data models, migrations, async/eventing, and the integrations that feed the platform
  • Own a domain end-to-end — from design through tested, observable, production-ready code, with the quality controls that back it up
  • Build and harden third-party integrations (wearables, clinical data): OAuth, webhooks, retries, idempotency, token refresh
  • Own your domain’s reliability: instrument it (metrics, traces, logs), define and defend its SLOs, write actionable alarms, and take a turn on-call. Contribute to the infrastructure that runs it (Terraform / AWS)
  • Raise the quality bar: meaningful tests, good reviews, and safety/privacy treated as design inputs (encryption, least-privilege, PHI handling)
  • Mentor mid-level engineers and lift the team’s standards
  • Use AI coding agents to move fast — and verify and own what they produce

Skills

  • Strong backend experience (Python / FastAPI / SQLAlchemy / Postgres or equivalent) and a record of owning features/services end-to-end
  • Solid grasp of API design, data modeling, testing, and integration patterns
  • Experience running services in production — observability (metrics/logs/ traces), SLOs, and enough infra/IaC familiarity to operate what you build (Terraform / AWS a plus)
  • A bias to ship and a sense of ownership beyond your own commits
  • Comfort using AI coding agents day-to-day, with the judgment to check them
  • Clear communication — code, reviews, and writing others can follow
  • AWS / Terraform, Snowflake / dbt, or Flutter exposure
  • Health / regulated software (SaMD, IEC 62304, HIPAA) or other safety-critical domains
  • Healthcare data / interoperability (FHIR, wearables: Withings / Polar / Whoop / Fitbit, Apple Health / Health Connect)

Company Overview

  • Clinical Ink develops electronic documents recording software for recording source data on mobile devices during clinical trials. It was founded in 2006, and is headquartered in Winston Salem, North Carolina, USA, with a workforce of 201-500 employees. Its website is http://www.clinicalink.com.
  • Company H1B Sponsorship

  • Clinical ink has a track record of offering H1B sponsorships, with 1 in 2026, 5 in 2025, 5 in 2024, 4 in 2022, 1 in 2020. Please note that this does not guarantee sponsorship for this specific role.
