Principal Software Engineer

Client is a VC-backed, cloud-native B2B platform transforming how hotels connect with global demand. Founded by serial travel-tech entrepreneurs and backed by Highgate Technology Ventures (HTV), we're building the next generation of hotel distributionautomated, scalable, and integrated directly with CRS/PMS systems.

Scale that speaks for itself:

1B+ search requests per day

40ms average response time

200M+ inbound messages daily

We're a remote-first, high-growth company with a strong engineering culture. Over

the past 18 months, we've tripled our team, achieved 100% year-over-year revenue

growth, and continue to scale rapidlywith real revenue traction and a growing

global footprint. Our focus remains on automation and low-latency infrastructure to

power real-time connectivity at scale.

Role : Staff / Principal Engineer (Java / Microservices / Distributed Systems)

Location: Remote (Work from Home)

We're looking for hands-on technical leaders to join as Staff or Principal

Engineersbuilders who can lead by doing. You'll be the backbone of architectural

decisions, drive scalability across domains, and solve complex distributed systems

problems while mentoring teams through execution.

Each Staff/Principal Engineer is expected to own multiple initiatives or projects

end-to-end, from design to rollout, working collaboratively across teams to drive business and

technical outcomes.

Responsibilities

Drive system design, platform architecture, and self-serve engineering capabilities

across high-scale microservices and real-time data pipelines.

Own end-to-end delivery of critical initiatives, from scoping and design to deployment

and scaling.

Own and lead multiple projects simultaneouslybe accountable for quality,

performance, and timelines.

Lead by example as a hands-on developer, picking up the most complex pieces and

turning ambiguity into working software.

Build scalable and resilient systems using Java (Spring Boot), Event-Driven

Architectures, and NoSQL (ScyllaDB/MongoDB).

Solve real-time, high-throughput challenges across search, pricing, availability, and

booking workflows.

Embrace AI-powered development methodology (Claude, Cursor) to increase product

release velocity and build accuracy.

Collaborate across teams (Product, Infra, Data, Architects) with a mindset of

ownership and partnership.

Conduct rigorous design and code reviews with attention to clean code, performance,

and maintainability.

Requirements

1013 years of backend development experience, with deep focus on Java (Spring

Boot, Hibernate)

Proven track record in owning systems, influencing architecture, and delivering

critical projects independently or in small teams

Strong experience with:

Distributed systems, event-driven architectures, SQS/Kinesis, backpressure, and

fault tolerance

ScyllaDB, MongoDB, or other NoSQL databases

Performance profiling, memory management, and latency optimizations

Deep systems thinking around consistency models, circuit breakers, low-latency

design, and platform reliability

Experience driving an automation-first culture, building tools, frameworks, or

internal platforms

Familiar with observability tools: Grafana, Prometheus, CloudWatch

Must be a goal-driven professional who focuses on driving measurable results and

can effectively prioritize activities that directly contribute to business objectives.

Self-starter, go-getter, and problem solver with a growth mindset

Comfortable in remote-first, async, and ownership-heavy environments

Nice to Have

Experience with LLM pipelines, RAG, or agentic AI workflows

Exposure to Databricks, Spark, or other large-scale data processing frameworks

Experience building internal platforms or golden paths to accelerate engineering

teams.

Knowledge of React or full-stack systems

Prior experience in B2B marketplaces or travel-tech is a plus
