What are the responsibilities and job description for the Sr. Backend/Platform Engineering Roles position at The Phoenix Group?
Senior Backend / Platform Engineering Roles
Location: New York City (Hybrid or Flexible)
We are working with a range of NYC-based, product-driven organizations across fintech, asset management, and enterprise SaaS that are building and scaling backend platforms supporting high-volume, data-intensive systems.
This posting reflects the types of senior backend and platform engineering roles we consistently see across these teams, rather than a single isolated opening. These environments tend to prioritize system reliability, clear ownership, and thoughtful technical decision-making as the business grows.
What These Roles Typically Involve
Across these teams, senior backend and platform engineers are responsible for:
- Designing, building, and maintaining backend services that support core business workflows
- Contributing to platform and system architecture decisions alongside senior engineers and technical leadership
- Improving reliability, performance, and observability in production environments
- Partnering closely with product, data, and infrastructure teams to deliver scalable solutions
- Owning services end to end, from design through deployment and ongoing support
Experience That Tends to Translate Well
Engineers who do well in these environments often have:
- Strong experience building backend systems using Python, Java, Go, or similar languages
- Experience working with distributed systems or service-oriented architectures
- Comfort operating in data-heavy or high-throughput environments
- Hands-on experience with cloud platforms such as AWS, GCP, or Azure
- A pragmatic engineering mindset focused on clarity, reliability, and long-term maintainability
Backgrounds We Commonly See
Many of the engineers placed into these types of roles come from:
- Fintech, financial services, SaaS, or other data-driven organizations
- Teams where correctness, resilience, and scale are critical
- Environments where senior engineers collaborate directly with technical leadership rather than working from narrowly scoped tickets
What Differentiates These Environments
Across these teams, backend and platform engineering tends to sit close to the core of the business. Engineers are expected to have ownership over meaningful systems, contribute to architectural direction, and understand how their work impacts the organization as it evolves.
Compensation
Compensation varies by organization and scope, but typically reflects senior-level responsibility and impact.
