Scientist, Computational Biology

Flagship Pioneering, Inc.•Cambridge, MA

3h•$115,000 - $165,000

About The Position

This role is with FL103, an early-stage biotech company founded by Flagship Pioneering, focused on developing breakthrough technologies for disease detection, monitoring, and treatment using liquid biopsies. The company aims to capture more comprehensive biological data from minimally invasive biospecimens to enable earlier disease detection and more effective interventions. The successful candidate will play a foundational role in building FL103's core platform and translating complex biological data into actionable insights. FL103 is seeking a highly motivated and experienced computational biologist to join their team. The candidate will be a driven scientist enthusiastic about developing state-of-the-art techniques to pioneer the detection of cellular dynamics from minimally invasive biospecimens. This position offers a unique opportunity to contribute significantly to the development of FL103's core platform.

Requirements

PhD in computational biology, systems biology, bioinformatics, computer science or related fields with 2-4 years of industry experience
Experienced in standard and advanced computational support of wet-lab experimental design
Understanding of NGS approaches and demonstrated ability to collaborate with experimental biologists to conduct quality control, design experiments, and optimize protocols
Experience analyzing -omics data (e.g., single-cell and bulk RNA-seq, mass spec) using a scientific programming language such as R or Python.
Strong hands-on experience analyzing mass spectrometry-based proteomics data is required; direct experience with raw mass spec data processing, QC, normalization, and feature extraction is strongly preferred.
Experience with both statistical inference and machine learning (e.g random forests, SVMs, neural networks, transformers, etc.).
Ability to manage multiple projects, working both independently and collaboratively within a dynamic team
Excellent written and verbal communication skills to present results and scientific data to the internal team and/or collaborators
Highly attentive to detail, flexible, and curious
Enthusiastic about playing a pivotal role in building the foundation of a new biotech company

Responsibilities

Develop, maintain, and scale computational pipelines for proteomics, transcriptomics, and internal proprietary assay data.
Integrate multi-modal biological datasets to identify disease-relevant molecular patterns, candidate biomarkers, and assay features.
Design and apply statistical, machine learning, and bioinformatics methods to improve assay sensitivity, specificity, reproducibility, and biological interpretability.
Partner with biologists, assay developers, and leadership to design experiments, define success criteria, analyze results, and validate key biological and computational hypotheses.
Collaborate with software and data engineers to build internal tools, dashboards, and user interfaces that enable scientists to explore, interpret, and pressure-test FL103 data.
Build literature- and knowledge-based contextualization workflows, including responsible use of LLMs, to connect internal findings with external scientific evidence and disease biology.
Develop rigorous analytical frameworks for comparing candidate markers, assay conditions, biological cohorts, and disease states.
Ensure analyses are reproducible, well-documented, and version-controlled, with clear standards for data provenance, code quality, and interpretation.
Translate complex computational analyses into clear biological and strategic recommendations for cross-functional teams.
Maintain deep scientific and technical expertise by staying current with advances in computational biology, liquid biopsy technologies, biomarker discovery, multi-omics analysis, and disease biology.
Communicate results clearly through presentations, written reports, technical documentation, and cross-functional discussions with the FL103 team.
