This is a high-impact role for a senior engineer who wants real ownership from day one. As a Senior Software Engineer (Contractor) at Thrive Global, you will own and evolve our enterprise platform end-to-end — responsible for both sustaining engineering (reliability, scalability, technical debt) and net-new feature development that directly supports our B2B customers and commercial growth.
You will start by working on our Coaching application, with the flexibility to move to other parts of the platform as priorities evolve. This is a fast-moving, lean environment, so we are looking for someone who brings the pragmatism of a startup — a bias to ship and iterate quickly — paired with the craft of an engineer who has seen the long-term cost of shortcuts. You will take ambiguous problems, break them into well-sized workstreams, and drive them to completion with minimal hand-holding.
How You’ll Contribute
- Own and evolve the enterprise platform end-to-end — responsible for both sustaining engineering (reliability, scalability, technical debt) and net-new feature development that directly supports B2B customers and commercial growth. You will start on our Coaching app and may shift to other areas of the platform as needs arise.
- Independently scope and deliver medium-to-large projects — take an ambiguous problem, break it into well-sized workstreams, sequence the work, and drive it to completion with minimal hand-holding.
- Partner closely with Product and stakeholders — translate business requirements into technical plans, surface trade-offs early, and keep cross-functional partners informed throughout delivery.
- Set a high bar for quality without sacrificing pace — bring a bias to ship and iterate fast, balanced with the craft and judgment to avoid costly shortcuts.
- Support reliability and incident response — provide on-call and incident support during US working hours to keep the platform healthy and customers supported.
Qualifications & Skills
- Senior-level software engineering experience, with a track record of owning systems or products end-to-end in a production environment.
- Demonstrated ability to scope and deliver medium-to-large projects independently, from ambiguous problem to shipped solution.
- Strong full-stack in TypeScript, with experience balancing sustaining engineering (reliability, scalability, technical debt) and net-new feature development.
- Experience building and supporting B2B / enterprise-facing software.
- Comfort partnering directly with Product and non-technical stakeholders to translate requirements into technical plans.
- Experience with on-call rotations and incident response.
- Pragmatic, startup-minded approach — able to move fast and iterate while maintaining a high quality bar.
- Requires meaningful daily overlap with the U.S. Eastern Time business hours, as well as sufficient overlap with the Ireland-based team to support collaboration and communication.
- Available to start immediately and engage as a contractor.
Who You Are
A self-directed senior engineer who thrives with ownership and minimal oversight, and knows which decisions warrant a stakeholder check-in.
A pragmatic builder who blends startup speed with engineering craft — you ship and iterate, but you don't accumulate avoidable debt.
A clear communicator who surfaces trade-offs and risks early and keeps cross-functional partners aligned.
Energized by ambiguity — you can take a loosely defined problem and turn it into a sequenced, deliverable plan.
Reliable under pressure, with the judgment to keep systems stable and respond effectively when incidents arise.
Quality-obsessed without being precious — you set a high bar and still move the work forward.
