Senior Software Engineer, Platform Observability Remote - Ireland

Overview

At Twilio, we're shaping the future of communications with a remote-first culture.

We deliver innovative solutions to hundreds of thousands of businesses and empower millions of developers to craft personalized customer experiences.

This role is for a Software Engineer on Twilio's Platform Observability team, focused on rebuilding and unifying our observability stack to enable faster incident response, deeper insights, and more cost-effective platform operations.

You'll help re-architect how telemetry flows and is utilized at Twilio-making it structured, accessible, affordable, and actionable.

Over the next 3 years, Twilio is rebuilding nearly every component of our observability platform, from data collection to real-time analytics.

You will drive core initiatives that move Twilio from fragmented tooling to a unified, OpenTelemetry-first observability stack built for scale.

You'll lead technically and strategically-designing platform components, influencing architectural decisions, mentoring engineers, and engaging with teams across Platform Engineering and R&D.

Responsibilities

Lead the end-to-end architecture and delivery of key observability platform components, with a focus on reliability, scalability, and usability.

Drive consistency and quality across all observability signals-logs, metrics, traces, and continuous profiling-building intuitive workflows for engineers.

Serve as a technical advisor and mentor across the platform org, guiding design decisions and aligning cross-team efforts with long-term architectural goals.

Deeply explore one or more problem areas (e.g., high-cardinality telemetry, distributed tracing correlation, compute cost insights), while ensuring the platform scales horizontally.

Collaborate with product teams, SREs, and developer experience groups to understand telemetry needs and integrate observability into core engineering workflows.

Design and build developer-friendly tooling and APIs to support incident response, performance analysis, and platform debugging at scale.

Leverage (and optionally contribute to) open-source standards like OpenTelemetry to ensure interoperability and extensibility.

Champion a pragmatic approach to observability-balancing performance, cost, and user value across diverse engineering teams.

Qualifications

Twilio values diverse experiences from all kinds of industries, and we encourage everyone who meets the required qualifications to apply.

If your career is just starting or hasn't followed a traditional path, don't let that stop you from considering Twilio.

We are always looking for people who will bring something new to the table!

Required :

Proven expertise in building and scaling observability systems (e.g., logging platforms, metrics pipelines, tracing infrastructure, or profiling tools).

Lead technical execution for major components of Twilio's observability overhaul, including shift to centralized S3-based data lakes, OpenTelemetry instrumentation, and ClickHouse-backed query engines.

Deep proficiency in at least one modern programming language (e.g., Go, Python, Java).

Familiarity with high-cardinality data challenges and telemetry correlation techniques.

Solid understanding of distributed systems and the challenges of observability in complex, microservice-based environments.

Experience with AWS, Kubernetes, and infrastructure-as-code tools.

Provide architectural guidance and thought leadership across teams, helping to establish telemetry standards, efficient usage patterns, and scalable platform abstractions.

Ability to make forward-looking technical decisions and lead others through ambiguity.

Familiarity with ClickHouse, Grafana Loki, Athena, or equivalent systems for log and metrics querying.

Contributions to open-source observability tools or communities.

Experience building cost visibility or FinOps tooling for cloud compute and telemetry pipelines.
